Legendary housemate Brian left the house on Tuesday night by scaling the walls of the sky room in the garden following an argument with Helen Wood.
Brian and Helen got into a row during a group task, and the pair were embroiled in a heated war of words, with Helen launching a vicious verbal attack.
"You need to argue with us so you make money sweetheart, so you make money out of being a scumbag," Brian shouted at her. "You act like you just walked out of a dustbin."
Helen hit back: "Straight jacket is in the store room, psycho... Brian you look like a rapist, you look like a murderer, murderer slash rapist. The man in the white coat is waiting for you Brian."
After going into the store room with Nikki Grahame and expressing his anger in the Diary Room, an emotional Brian planned his escape in the garden, with the housemates unable to stop him.
Helen was given a formal warning by Big Brother, where she apologised for her actions.
Speaking on Big Brother's Bit On The Side, Brian told host Rylan Clark that Helen and Marc O'Neill were "antagonising" him.
"She tries to manipulate things and turn things around," he said. "I'm a 6ft 4 lad so it's easy for her to say, 'Oh no, he's done that to me'.
"I just thought, 'I don't need to be around people not being nice to me.' I've got more self-respect. I'm not even going to say anything bad about them because I want to hold my head up high with dignity in this situation. Everyone has seen what they're like."
Appearing to be in an upbeat mood, Brian said he felt "embarrassed" to have cried in the house. "It's embarrassing," he told Rylan. "You know what it's like in Essex, I'm going to get absolutely rinsed when I go out for a run."
Brian won Big Brother in 2007. He re-entered the house two weeks ago as a legendary housemate as part of Big Brother's Time Warp twist.
