[Rob!]

There's been quite a few moments of people wanting to walk so far - and we're only at day 21! But who will it be?

Shabby - Shabby's performance tonight showed us that she clearly has no control over herself when she gets angry and upset, and she is more than aware of this. Will she carry out her plan to leave if/when Caoimhe leaves, or will it cause another big row to make her realise enough is enough?

Ben - Ben has hinted quite a few times that he finds life in the house difficult, and he often finds himself at odds with the rest of the housemates. Moments like the stick the housemate task and his various arguments with the others have shown us that he isn't altogether comfortable with some of the house activities and a lot of the housemate conversations. Will it get too much for him?

Sunshine - Despite the fact that she has some fun moments in the house, there have certainly been moments when Sunshine appears to be one of the most isolated housemates in the house. She is one of those housemates who the others find quite easy to gang up on, not dissimilar to Ben, so could it get to the point where tiny issues start to get the better of her?

John James - In a similar way to Shabby, JJ is quite good at losing his temper and letting his mouth fight his battles for him. He gets angry quite quickly, and it could get to the stage where he could end up falling out with someone like Josie quite quickly, someone who he already stated that he would feel gutted to lose. Could his temper get the better of him to the point where he needs to leave?

Or could it be some of the others? Could Dave lose sight of the lord? Does Nathan have a point where cooking isn't enough? Or is it possible that Steve could think he is above all the dramas that keep kicking off in the house?

What are your thoughts? Don't leave me hanging guys!
