I also think that may have been the point.
He was asking "Why won't I be your friend?" like he was slightly hurt that he wasn't included. Even though Perez said that they'd be friendly acquaintances Then laughed it off in his 'Cheggers' way.
Which suggests to me that he did like Perez up until at least that point.
Don't forget all the laughs they had together at times.
He was actually encouraging Perez to dance in the garden as the others in the bedroom were going mental. Keith was practically wetting himself laughing.
He can't really pretend that he wasn't very pally with Perez and didn't have laughs with him. Because we saw it.
In fact if Perez wasn't having a laugh with him the 'other lot' certainly wouldn't give him much in the way of the time of the day.
If Perez wasn't there I'd hazard a guess that he would be the main target of their venom at a very early stage. Just as it started to happen once Perez left.
I also think he's playing the part of a people pleaser. It wasn't until he heard a few boos for himself that he decided to vocally distance himself from Perez.
Now out of the house I think he's recognised that he will be seen as 'nice' in the eyes of the public if he disassociates himself from Perez.
