Hmmmmmmmmmmmm - he obviously never intended to be there for the long haul. I remember in the first day or two (when he was first nominated) he kept saying something along the lines of - do you think it's gonna be that easy, will we still get the money after only a couple of days - he was pretty excited at the prospect of an early exit. He'd obviously discussed these pre booked gigs and been reassured that he'd get paid just for being there.

Not sure if I'm making sense but I know what I mean

Watching what Perez does in this clip before Alexander called him the f word. It starts around 13 minutes in. The gang all decided once again to try to isolate him so he went over and sat where they were and smiled. They all laughed at him. He was wearing dark sunglasses so why did Alexander jump on him for smiling at him? He was looking for a fight.
He was also scaring the others with his fuming temper and remarks in the kitchen. Who wouldn't be scared .Oh and 14 minutes in Nadia once again saying her piece to Perez for his behaviour, you know Nadia constantly wrongly accused of never saying a word to him?
5 minutes in KH trying to make Keith join in the bullying isolation with the juveniles and failing.
