In Friday night's live show we saw a switch between this year's two houses as two of the housemates were 'evicted' into the Other house and two of The Others moved into the main house.
During an explosive evening in the house afterwards, which played out in last night's episode, twin sisters Victoria and Emma broke out of the Big Brother compound.
The pair were still absent at the end of the episode but tonight's show reveals what happened next.
Emma returns to the house alone, continuing the show in her own right.
In the Diary Room, Emma explains to Big Brother why her sister chose to leave the house last night.
She says: “Victoria thought she was prepared but didn’t expect that level of intensity.”
Channel 5 confirmed in a statement this weekend: "Victoria has this morning decided to leave the Big Brother house, her twin sister Emma will continue as a housemate in Big Brother."
It's been a hectic week for BBUK and we're not even a full seven days into the series.
In what could be another blow to the show, Andy West admits to Big Brother in tonight's episode he's also thinking about leaving.
He confides in the Diary Room: “They think I look down on their conversations, I probably would… it’s a conversational (sic) yoghurt of s***e. Me and Georgina had a conversation about World War II, for five minutes, then it was back to fake tan.”
Big Brother airs tonight at 9PM on Channel 5.
