Lisa tells Mario to think positive

Lisa told boyfriend Mario to "stop being negative" this morning, after he expressed his doubts about tonight's eviction.

When talking about some ear drops that Big Brother had given him, he told Lisa that he would give them to her when he leaves tonight.

Lisa said: "Stop talking like that, you don't know yet."

Mario agreed reluctantly, adding: "There could be a twist."

The couple were then reminded by Sylvia that Big Brother reserves the right to change the rules at any time, "even if it's not fair".

"That's true," Lisa said. "Some people have been put back in."
