Christopher Hall's fellow BBUK housemates fear he's losing the plot on tonight's show.
At the top of the show and in the Diary Room, Christopher talks to Big Brother about the fact that Mark seems to be distancing himself after the comments from the focus group.
Christopher explains that they have made a decision to put the brakes on things till they leave the house. He says: ‘I’m no-one’s mug.’
Later on, Christopher does impressions of Mark into the mirror and ends up shouting ‘lies’ repeatedly.
The other Housemates are listening to him in the garden and Ash says that Christopher is ‘cracking up.’ He adds to Mark that Christopher is obsessed with him and copies his sayings.
In the evening and Mark clears the air with Christopher and admits that he does pick at him and has been cagey and blown hot and cold.
He tells him that one of the reasons for this is that he hasn’t come out to some members of his family.
Christopher admits he has been confused and that he’s fine with the decision they have made to wait until they leave the house before fully exploring the possibility of a relationship but wants to know that there is ‘something to wait for.’
Big Brother 2014 airs at 9PM on Channel 5 tonight.
