From what I've just seen, he seriously likes her big style. Remember the issue with Jay and Ness, all that '
kissing with eyes open means there's no love', well Stu has been kissing Michelle with eyes closed. So if you believe in all that, I'd say he has strong feelings for her, and will want to be with her after BB5 is over.
Also, Jay and Vic are hoping for another double eviction.
