Michie begins planning on who he should banish from the house. Michie chooses to banish Cliff, Kemi, Jessica and David from the game. The banished HouseGuests are escorted to the backyard where they begin their competition.

• Banishment Competition ("The Search for Camp B.B."): In the dark, the competing HouseGuests must find their way through the forest back to Camp B.B. Along the way there are fake camps such as "Camp Bee Bee" or "Camp B-Ball." The first three HouseGuests to arrive back at the House are allowed re-entry to the game while the fourth will remained banished from the game. Cliff was the first to return to Camp B.B., followed by Kemi and Jessica and were allowed re-entry to the game. David, remained banished from the game. The HouseGuests participated in the first Head of Household competition.
• Head of Household ("Color Wars"): The competition was played in pairs. As Camp Director, Michie did not participate and was allowed to choose the pairs. Each pair had to hang onto a log suspended in the sky. If someone falls off their log, they were eliminated. The HouseGuest who remained on their log the longest became the HoH. Christie won.^[24]

Speculation begins on who Christie will put up on the block. Meanwhile, alliances begin to form making other HouseGuests suspicious.

• Whacktivity Competition ("Nightmare Comp: This Stinks"): HouseGuests are informed that over the next three weeks everyone will compete in a Whacktivity. Only five people will compete each week. The winner of each week will receive a power. The competing HouseGuests must smell the three trashcans in front of them as well as other items and try to match the smell in their trashcans. Once they think they've identified the smell they must hang the identifier from the can and must buzz in once all three cans are labeled. The first HouseGuest to correctly identify all three items will win. Cliff, Isabella, Kathryn, Nicole and Ovi competed in the first week. At the end of the third round, Ovi correctly identified all three smells and won the competition. The power Ovi received allows Ovi to make the current HoH rename their nominees for the week in the middle of the night once all others are asleep. The original nominees for the week are safe and cannot be nominated again. On Day 8, Cliff and Kathryn were nominated for eviction by Christie.^[26]

Ahead of the Power of Veto, the HouseGuests picked players for the competition. Christie, Cliff and Kathryn, along with Sam, Jack and Nicole, participated, with Big Brother 20 winner Kaycee Clark returning to host.

• Power of Veto ("Food Fight"): This competition was played by HouseGuests one at a time, inside the Camp B.B. Mess Hall, where the competing HouseGuest must attempt to catch as much food as they can as it falls from the sky. The more food caught, the more points HouseGuests received. The HouseGuest with the most points at the end of the competition won the PoV. Sam won with 21 points, then began debating on whether he should use the PoV, meanwhile, Christie begins thinking of a potential replacement nominee if the veto is used. Sam used the Power of Veto to remove Cliff from the block, forcing Christie to nominate Ovi as a replacement.^[28]

HouseGuests begin discussing final nominations and deciding who they want to evict. They then participated in the live vote and eviction by voting on who they wished to evict from the house. On Day 15, by a unanimous 12–0 vote, Ovi was the first to be evicted. Julie informed the HouseGuests that Ovi had been evicted from the house and the "Camp Comeback" twist was unleashed. The twist allows the evicted HouseGuests to remain inside the house where they live upstairs in a special room. They will continue to live inside but not participate in competitions or evictions. Once four HouseGuests are in Camp Comeback, they will compete against each other for a chance to re-enter the game. David then re-entered the house.

• Head of Household ("BB Fireworks Quiztacular"): The HouseGuests watched a fireworks display. Julie then asked a question to which the correct answer is either red, white or blue. If a HouseGuest answers correctly they move on, if a question is answered incorrectly, they will be eliminated from the competition. The last HouseGuest in the competition will become the next HoH. Jack won and became the second Head of Household of the season.^[30]

The HouseGuests begin to make new plans with the Camp Comeback twist unleashed into the house.

• Whacktivity Competition ("Chaos Comp: For Goodness Snakes"): In this competition the competing HouseGuests are placed in a room full of snakes. On a table there are tanks with three other snakes. The HouseGuest must find a match in the room for the snakes in the tanks. Once they think they have found a match for each of the snakes they must buzz in. If correct, they are finished; if incorrect, they must continue trying. The HouseGuest who matches all three snakes in the shortest time wins. Jack won with a time of 40 seconds. Jack received the power which allows him to force a re-draw on players for the Power of Veto competition. The HouseGuests then saw a promotion for the new CBS series Love Island hosted by former Big Brother 20 HouseGuests Swaggy C, Bayleigh Dayton, Winston Hines and Brett Robinson. They were told that the winner of the next PoV competition would receive a trip to Fiji. Jack begins pondering nominations and has trouble deciding whom to put up. On Day 17, Jack nominated Jessica and Kemi for eviction.^[32]

Ahead of the Power of Veto, the HouseGuests picked players for the competition. The Head of Household, Jack, Kemi and Jessica, along with Isabella, Michie and Sam, participated, with Big Brother 20 runner-up Tyler Crispen returning to host.

• Power of Veto ("Froggy Style"): HouseGuests had to stack plastic frogs on a stand, but they could only do so if there was still water in their "aqua clock." If their water was running low, they had to refill it to have more time. After 30 minutes, they could not fill their aqua clocks anymore. After their aqua clock ran out, their score was the number of frogs that they stacked. The HouseGuest with the highest score won the Power of Veto and a five-day trip to Fiji. Sam won with 18 frogs and, on Day 20, decided to not use the Power of Veto, keeping Jack's nominations the same.^[34]

Christie overheard Cliff talking about his new alliance, "The Fellowship of the Zing," with Ovi and Nicole and the four pairs in the house. She relayed this information to the dominant alliance, made up of the four pairs. The HouseGuests had decided to evict Kemi for the entire week, but after the Veto Ceremony, the HouseGuests became undecided after Kemi told Michie that Isabella was playing both sides of the house. On Day 23, by a 10–1 vote, with Michie casting the only vote for Jessica, Kemi was the second to be evicted and joined David and Ovi in Camp Comeback.

• Head of Household ("Power Shot"): HouseGuests take turn throwing arrows underhand at a target with points. The HouseGuest whose arrow lands on the highest point ring wins the Head of Household; however, if someone does not want to be the HoH, then they could aim at two red dots at the top of the board, one earning them $5,000 and the other one earning them safety for the week. These dots could only be hit once and neither prize was claimed. Nick won with a score of 90.^[36]

The House begins to suspect who cast the rouge vote during the eviction process. Meanwhile, Nick begins debating on who to put up. Nick mentions that he's considering putting up Cliff and Jessica. Michie attempts to pin the rouge vote on Nicole but confides in Michie admitting who he actually voted for. Nick suspects Michie is up to something as he continues to bring up the vote with Nicole's name and suspects the vote could've been him.

• Whacktivity Competition ("Panic Comp: Madagascar Mayhem"): HouseGuests had to search through Madagascar hissing cockroaches for rebus puzzles to solve a message: Don't meet Julie on eviction night. After figuring out a word, they had to grab letters off a board of letter combinations and spell the message. The HouseGuest to complete the message in the fastest time wins the Panic Power. Christie won with a time of 7:41. Nicole told Isabella and Nick that the Gr8ful alliance is targeting them; however, on Day 24, Cliff and Jessica were nominated for eviction by Nick.^[38]

The dominant alliance, Gr8ful, along with Sam, met in the Head of Household room. Isabella told them the story Nicole told them about how the Gr8ful alliance, minus Isabella and Nick, were targeting her and Nick, as well as calling them bullies. The others, getting caught in the lie, started getting furious and made Isabella and Nick change their minds and completely gun after Nicole to get her out this week. The eight, along with Sam, start a new alliance called Unde9able.

• Power of Veto ("The Haunting of Kaitlyn Herman"): Former Big Brother 20 Kaitlyn Herman returned to host the competition. HouseGuests had to enter Kaitlyn's Nightmare World where they would find pieces of Kaitlyn's body. The first HouseGuest to put all the pieces together and complete the puzzle wins the Power of Veto. Kathryn finished first and won the Power of Veto. Before the Power of Veto Ceremony, Christie had a meltdown after her intuition told her that she's going up on the block. Christie starts contemplating using her Panic Power to make sure she is safe. Christie ends up not using her power; on Day 27, Kathryn took Jessica off the block, forcing Nick to nominate Nicole as the replacement nominee.^[40]

The Gr8ful alliance formed a new alliance that excludes Nick and Isabella called the Six Shooters. The Six Shooters contemplate saving Nicole over Cliff. Nick and Isabella believe they secured the votes to evict Nicole while the Six Shooters progressively become more committed on the plan to blindside Cliff and send him home. On Day 30, by a vote of 6–4, with Isabella, Jessica, Kathryn and Sam voting to evict Nicole, Cliff became the third person to be evicted and entered Camp Comeback.

• Camp Comeback Competition ("Path to Redemption"): Cliff, along with David, Ovi and Kemi, competed to re-enter the game. The "Camp Comebackers" had to roll balls down a platform that they could tilt and into their receptacle. The camper who sinks six balls in their receptacle within three minutes wins their way back into the game. Cliff won with 51 seconds left on the clock and re-entered the game and joined Big Brother 18 HouseGuest Victor Arroyo as the only HouseGuests in Big Brother history to re-enter the game twice in the same season, while David, Ovi and Kemi were forced to immediately leave the house for good.^[42]

After the vote, the Unde9able alliance blew up at each other and disbanded, leaving Nick and Isabella on the outs.

• Head of Household ("Patch Perfect"): In each round, they were given a question about a board of Big Brother merit patches. If two people answer incorrectly, they are both out of the game, but it everyone answers correctly, the two people who buzzed in the slowest would be eliminated. It came down to Jack and Cliff. The HouseGuest to answer the question correctly first won the Head of Household. Cliff became the fourth Head of Household of the season.

The Have-Nots this week were Christie, Michie, Kathryn, and Tommy. Cliff tells Nick and Isabella that he is targeting the Six Shooters, the six people who voted to evict him. Michie comes up with a plan to be put up as a pawn. On Day 31, Jack and Michie were nominated for eviction by Cliff.^[44]

A Have-Not ceremony took place, in which Cliff (as Head of Household) had to name the first four Have-Nots for the summer. He chose Christie, Michie, Kathryn and Tommy, who had to eat slop for the week, take cold showers and sleep in the same room as the Camp Comeback room. After picking players for the Power of Veto competition, Jack used his Chaos Power to force a re-draw on the three additional players.

• Power of Veto ("Take It Off"): Similar to the first Roadkill competition in Big Brother 18, each houseguest had to strip down to their swimsuits while holding down all three buttons. This time, it was on a jet ski and any buttons released will speed up the timer: 10 times for one button, 30 times for two buttons and 60 times for all three buttons. Michie won the Power of Veto and, on Day 34, saved himself off the block, forcing Cliff to nominate Isabella as the replacement nominee, while Christie elected not to use the Panic ability for the second Veto Meeting in a row with only two more opportunities remaining to use it.^[46]

Now on the Nomination Block as the replacement for Michie, Isabella begins campaigning to stay in the House and makes compelling arguments. The production team shows a segment featuring Cliff's family as they discuss how he's doing on the game. The two nominees, Jack and Isabella, are given a final chance to try and convince the HouseGuests not to evict them. The HouseGuests then participated in the live vote and eviction by voting on who they wished to evict from the Big Brother house. On Day 37, by a vote of 8–2, with Nick and Sam voting to evict Jack, Isabella was evicted from the House.

• Head of Household ("Pose in Ivy"):^{[lower-alpha 1]} HouseGuests had to stand and hold on to ropes in the air. If a HouseGuest were to fall off, they were eliminated and had to draw a chip from a bag. In the bag were two punishment chips that gave the drawers a punishment. The HouseGuest who outlasted all the others would become the next Head of Household.^[48]

• Head of Household ("Pose in Ivy"):^{[lower-alpha 1]} Holly outlasted all the others and became the Head of Household. Christie and Tommy picked the punishment chips and were given a punishment for the week.

The Have-Nots this week were Jessica, Nicole, and Sam. On Day 38, Nick and Sam were nominated for eviction by Holly.^[50]

• Power of Veto ("Counting Sheep on BB Farm"): In head-to-head rounds, HouseGuests were given a target number and had to herd sheep, identified with a number, into a sheep pen. The sum of the numbers the sheep represented had to equal the target number. The HouseGuest to get to the target number first won the round and another round would start. Nick won and, on Day 41, saved himself off the block, forcing Holly to nominate Kathryn as the replacement nominee after Christie did not use her Panic Power for the third week in a row.^[52]

A plan was set in motion to flip the vote to evict Kathryn and use Sam to go after the Six Shooters; however, after a very hectic lead up to eviction, including the breakup of the dominant Six Shooters alliance shown on Sunday's episode, the plan crumbled and flipped back to a unanimous vote by the time Chen Moonves announced it was time to vote. On Day 44, by a unanimous vote of 9–0, Sam was evicted.

• Head of Household ("Camp Expo"):^{[lower-alpha 2]} The HouseGuests started studying pictures that they would later be asked questions about.^[54]

Shown in a flashback, the full story of the chaotic, yet unsuccessful effort to flip the vote to evict Kathryn was explained. The fight ultimately ended up with Christie and Michie yelling at each other over a "secret trio" of Kathryn, Holly and Michie. As a result, the Six Shooters alliance fractured into smaller alliances of duos and trios. Kathryn, who had been affiliated with the Six Shooters alliance, was cast out. Cliff, Nick, Nicole and Jessica overheard the fight; Kathryn joined them after being outcast.

• Head of Household ("Camp Expo"):^{[lower-alpha 2]} Holly gave the HouseGuests true or false questions about the pictures that they had just studied. If they got it right, they moved on to the next round, but if they got it wrong, they were eliminated from the competition. In the end, Jessica beat out Kathryn to become the Head of Household and, on Day 45, nominated Jack and Michie for eviction.^[56]

• Power of Veto ("Tossed in Space"): HouseGuests took turn catapulting an object into an area with a certain number of points. The HouseGuest who received the fewest points would receive the prize or punishment associated with their placement. The next person who was knocked out could either trade their current prize for their prize, or keep their prize. The HouseGuest to finish with the most points in the final round was able to pick whichever prize they wanted. In the end, Jack and Michie won a punishment, Tommy won a costume, Kathryn won a trip to Hawaii, Nick won $5,000 and Jessica won the Golden Power of Veto. Talks began to erupt about where Nick's vote lies after Jessica overheard Nick tell Christie that he is voting out Michie. Jessica made sure Nick was voting out Jack. Jessica talks with Holly, Kathryn, Nicole and Michie about potentially removing Michie off the block and putting Nick up after they talked about how he was playing both sides. However, on Day 48, Jessica decided not to use the Power of Veto, keeping her own nominations the same.^[58]

Michie said he wouldn't campaign against Jack. The former Six Shooters had a meeting in the Have-Not room, but nothing was decided upon except for the fact that the "Six Shooters" alliance is done. Jack talked with Nick and Cliff to try to get their votes. On Day 51, by a vote of 6–2, with Analyse and Christie casting the only votes for Michie, Jack was evicted and became the first jury member. In his eviction interview, Jack was shown clips of controversial comments he'd made during the season.

• Head of Household ("Time Me a River"): Inspired by Big Brother 20's "Perfect Timing," HouseGuests had to get to the other side of the yard in a canoe as close to nine seconds as possible. The HouseGuest with their time closest to nine seconds won the Head of Household. Tommy won with a time of 8.9 seconds.^[60]

Tommy plans on targeting Kathryn; he talks with Christie about plans where she would be guaranteed to go home. Tommy also talks about getting the Six Shooters (minus Jack) back together for the week.

• America's Field Trip Competition ("Eggscape the Coop"): After America voted, Analyse, Christie and Michie competed in the competition. The HouseGuests had to transfer eggs through walls made of chicken wire. At the end of the wall, they had to roll the egg and knock down four pieces of wood spelling out the word SAFE. After all four boards were knocked down, they finished the competition. Michie finished first and received immunity. Analyse finished second and received a punishment. This meant Christie did not finish and thus lost the competition, becoming a special third nominee.

Nick promises to Tommy and Christie that if he wins the Power of Veto, he would remove Christie off the block. Analyse receives her punishment: she has to wear a chicken costume. On Day 52, Cliff and Kathryn were nominated for eviction by Tommy, alongside Christie.^[62]

• Power of Veto ("OTEV the Paranoid Pigeon"): At the beginning of each round, the HouseGuests were given a clue about a past competition by OTEV. They then had to slide down, find the item with the correct competition name on it and climb back up. The last HouseGuest to make it to the top (or if a HouseGuest got the answer wrong) would be eliminated from the competition. The last HouseGuest standing would win the Power of Veto. After it came down to Nick and Tommy, Tommy beat Nick up the slide and won the Veto and, on Day 55, took Christie off the block; however, since Christie was a special third nominee, no replacement nomination was made. Therefore, Cliff and Kathryn became the final nominees.^[64]

Nick gives Cliff an offer to form a six with him, Christie, Tommy, Nicole and Analyse to which he said he would "do in a heartbeat." Nick gives the same offer to Nicole, but she doesn't trust Nick. Nicole becomes the swing vote between evicting Cliff and Kathryn and both nominees campaign to Nicole to keep them. After Nicole tells Jessica about the new six-person alliance, Jessica tells Kathryn about the alliance they were left out of, throwing Nick and Cliff under the bus. This news spreads to Michie and Holly, who plan on targeting Christie, Tommy, Nicole and Analyse. On Day 58, by a vote of 6–1, with Jessica casting the only vote for Cliff, Kathryn was evicted and became the second jury member.

• Head of Household ("Aug-toberfest"):^{[lower-alpha 3]} HouseGuests had to slide across a slippery path and deposit "beer" in their beer stein. The first HouseGuest to retrieve a ball from inside their stein won the Head of Household.^[66]

• Head of Household ("Aug-toberfest"):^{[lower-alpha 3]} Michie won the Head of Household.

On Day 59, Michie nominated Analyse and Christie for eviction.^[68]

Christie starts thinking about Nick playing both sides. She tells both Analyse and Tommy about her thoughts, but blabbermouth Tommy goes to Nick and asks if he was working with the other side. He denied making a deal with them and he gets upset after he feels like no one trusts him.

• Power of Veto ("Coral Grief"): HouseGuests had to balance different sea creatures of different weights on a moving structure. The first HouseGuest that hung all ten creatures and hit their button won. Michie beat all of the other HouseGuests and rang it, winning the Power of Veto, but on Day 62, chose not to use it, keeping his nominations the same.^[70]

The vote starts flipping to evict Analyse after Christie talks with Michie about targeting Nick for future weeks. Nick overhears Christie talking about instigating a fight on Day 63 to paint a bigger target on Nick, dubbed as "Taco Tuesday." On Taco Tuesday, Christie calls out Nick for playing both sides of the house and throwing competitions, which Nick denies. On Day 65, by a vote of 5–1, with Nick casting the only vote to evict Christie, Analyse was evicted and became the third jury member. As a part of Prank Week, on Day 64, HouseGuests had to stay up during the night to listen to an exorbitant number of bird names and sounds as a joke to make the HouseGuests think that was for the Head of Household competition, but before the comp, they were informed about Prank Week and that the competition had nothing to do with bird sounds and names.

• Head of Household ("Prank Shot"): HouseGuests had to roll a ball on a plank extending over number slots from 1–50. As the numbers get bigger, the plank got narrower. The two HouseGuests to receive the lowest scores will receive a special punishment. Holly became the ninth Head of Household with a perfect score of 50. Jessica had the lowest score with 3, while Cliff and Nicole tied for the second lowest with 18. They all received the punishment.^[72]

In a flashback prior to the eviction explaining how Christie saved herself and evicted Analyse.

Michie and Holly talk about how the pranks from Prank Week will affect her Head of Household powers. Cliff, Jessica, and Nicole receive their punishment: they must make pies and then smash them in the face of the person the announcer tells them to. Cliff, Holly, Michie, and Nicole make an alliance aiming to reach the final four together.

Zingbot 9000 appeared this episode and delivered "zings" to the HouseGuests.

• Power of Veto ("Free the Zing"): HouseGuests had to use a lever and pulley system to get balls up a wall and knock out twenty-seven cameras to help Zingbot escape the "Zing-itentiary". Michie ended up completing it first, winning the Power of Veto.

The House starts realizing that Nick is America's Prankster. Nick starts telling people he is the Prankster, and by the Power of Veto Ceremony, the whole house knows that Nick was the Prankster. On Day 69, Michie decided to not use the Power of Veto, leaving Christie and Nick on the block and vulnerable to eviction.^[76]

Note: At the beginning of this episode, the starting sequence showed videos and images from last season as a prank to the viewers.^[76]

Nick starts campaigning for votes, knowing that he was likely getting evicted. On Day 72, by a vote of 5–0, Nick was evicted and became the fourth jury member.

• Head of Household ("Hold on Fright"):^{[lower-alpha 4]} HouseGuests had to hang on to a wall and stay on the longest. Once a HouseGuest fell off the wall, they were out of the running for HoH. The HouseGuests who outlasts all the others became the Head of Household.^[78]

• Head of Household ("Hold on Fright"):^{[lower-alpha 4]} It came down to Michie and Tommy, and when Michie coerced Tommy down with the agreement of safety for the week, Michie became the new Head of Household.

Michie tells Christie he plans to nominate her and Jessica, but explains that Christie would only be a pawn. The new final four alliance of Cliff, Holly, Michie, and Nicole agree that if the Veto is used on either Christie or Jessica, Cliff would be the replacement. On Day 73, Michie nominated Christie and Jessica for eviction.^[80]

Michie and Holly start fighting.

• Power of Veto ("Hide and Go Veto"): HouseGuests had to hide a life preserver inside the House. After they were hid, HouseGuests had to search for other life preservers. After the fifth life preserver has been retrieved, their names will be announced. The HouseGuest whose life preserver who wasn't found would win. Tommy's life preserver was not found, meaning he won the Power of Veto.

On Day 76, Tommy decided to use the Power of Veto on Christie. Michie nominated Cliff as her replacement, making the final nominations Cliff and Jessica.^[82]

On Day 79, by a vote of 4–0, Jessica was evicted and became the fifth jury member.

• Power of Veto ("What the Bleep?"): In this competition, Julie showed the competing HouseGuests clips of the show from throughout the summer that included conversations or speeches from evicted HouseGuests. However, one word or phrase was "bleeped" out and the HouseGuests must choose the correct word or phrase from two answers. The HouseGuests were then shown the rest of the clip. Answering correctly earned the competitors a point. The HouseGuest with the most points at the end became the winner. Cliff had the most points and won the Power of Veto.

Cliff decided to not use the Power of Veto, leaving Christie and Tommy vulnerable for eviction. By a vote of 3–0, Christie was evicted and became the sixth jury member.^[84]

• Head of Household ("BBFlix & Chill"): Three fake movie poster were shown to the HouseGuests. A group of friends talked about what movie they wanted to watch, giving the HouseGuests clues on which movie they wanted to watch.

The first HouseGuest to earn five points would win the Head of Household. Michie won.

On Day 80, Michie nominated Cliff and Tommy for eviction.^[86]

Tommy tells Michie and Holly that he knew Christie before entering the House.

• Power of Veto ("BB Comics"): HouseGuests had to memorize comics of the HouseGuests while flying on a zip line. Then, players had to choose which of the given comics was the correct comic. The HouseGuest with the lowest time after giving the sixteen correct comics would win. Nicole won the Power of Veto with a time of 10:58.

Very soon after Nicole wins the Veto, Michie and Holly discuss the situation where if Nicole uses the Veto on Cliff, then Holly would automatically have to be nominated as she would be the only option. They also discuss how Cliff and Nicole would be the only votes to evict, meaning that whoever they decided to evict would go home. However, Nicole tells them that she is using it but promises that Holly will not be going home. Nicole then goes to Tommy and tells him that the decision isn't final and either one of them could be going home. On Day 83, Nicole decided to use the Power of Veto on Cliff. Michie had to automatically nominate Holly as his replacement, making the final nominations Holly and Tommy.^[88]

  • Part 3: ("The Jury is Out") Holly and Michie had to watch a series of videos featuring jury members. The jury members made three statements about their time in the Big Brother House.
