Was looking around some of the message boards and I came across this one - I haven’t seen this series btw but anyway...
Mark Henderson from BB12 didn’t walk, apparently he was actually ejected but they covered it up as a withdrawal. Supposedly after Jay shat in the freezer, as a revenge, Mark wanked into a sandwich and gave it to Jay
But supposedly, since BB were trying to cover up the freezer incident up, they couldn’t really show this as it linked to it, so they got him to pretend he wanted to walk.
