I'm thinking Sam. He doesn't have much support, as far as I've seen. He also got the invisible edit today, with the eviction tomorrow, and straight after a whole weekend of no Big Brother (and only 30 mins - 2 mins excluding ads - on Friday).
Probably Sam, don't really want him to go but I don't want the others that are nominated to go either. Also, I hate those "OH NO I'M NOMINATED" faces they always make them do.
