Big Brother 6 winner Anthony revealed that he found Nick and Victor funny during his date with Makosi, prompting her to become suspicious of their friendship.
After she had started asking questions, Victor complained that Anthony is a "moron" and told Nick: "It's supposed to be a secret show."
Later, the pair told Makosi that they had a task from the Tree Of Temptation and promised to reveal everything.
"We'll all talk at midnight," Victor said. "You want to know what's going on. Well, all will be revealed, but it's a secret. You got to keep shut or I will feel the wrath of the Tree Of Temptation."
Victor and Nick also urged Makosi to convince the other housemates to go to bed early and reassured her that they won't do anything bad to her.
"There's nothing to be concerned about," Victor said. "No-one's going to drown in the pool... We're going to be in the nest."
"It's nothing horrible," Nick agreed. "You'll laugh like a drain."
