Charleston White enters as a guest visitor and is given the run of the house. The audience floods Charleston with TTS messages; he repeatedly walks down to production basement in disbelief and walks back up. Sam tells the cast Charleston will pick the next person eliminated.
Octavius is walked into the house the night before Charleston White's full visit, giving the cast a guest stretch that runs continuously across Days 17 and 18. Octavius (no canonical entity) is mentioned in body only.
Cube of prop money + Taylor returns as poker dealer "Carrie"
Sam comes up with Cowboy carrying a transparent cube of prop money meant to represent the $50,000 prize, placed on a poker table in the lounge. Production then brings Taylor back as the dealer under the fake name "Carrie." The audience floods TJ with TTS messages cheering him on to "take initiative" and rejoin Taylor at the table — a deliberate re-test of his Day-15 decision.
Brian eliminated by audience vote; Charleston picks Delaney; Octavius leaves
Charleston returns Day 18 and explains he won't reward the prize to anyone he can't justify it to. He picks Delaney to be eliminated. Sam announces Brian is also out via audience vote. Octavius leaves the same night. Jimmy is dragged down to production basement in a "you're eliminated" fakeout, painted in clown makeup, and brought back at the last minute.
Charleston picks Delaney for elimination; she leaves
Charleston White, having spent the day touring the house, walks back in and tells the cast that production didn't want to give $50,000 to anyone who'd squander it. He picks Delaney to leave the show. Delaney says her goodbyes and exits.
Brian eliminated by audience vote after the producer-word rule is enforced
Sam announces a rule that anyone using the words "producer" or "production" loses their slot in the next elimination challenge. After the next group session — where Jimmy slips and uses the word — Brian is then revealed to be the one eliminated by audience vote. Sam tells him outright that it came down to a vote.
Jimmy's "kicked off → painted as a clown → reinstated" reversal
When Jimmy slips up on the producer-word rule, Sam announces that Jimmy is being kicked off and pulls him to the basement. At the last minute production decides to keep him on, paints his face in clown makeup, and walks him back into the group session. Jimmy sits down in clown makeup and tells the room ominously, "we all have to make sacrifices to survive, don't we?"
Exit
Octavius is dropped from the show as part of the same cluster
Production also decides to drop Octavius from the show in the same cluster of decisions, ending his short visit-turned-stay. (Octavius has no canonical entity slug; his name is mentioned in body only.)
