The fifth episode of Tough Enough spells the end for Ryan Howe (Skidmarks).
It was just a matter of time before they knocked Ryan out. Stone Cold said it best - the third strike means he's out.
I WOULD say that I'd expect Eric to be voted out, but it seems like every time I say that, he seems to last another week. So by default, I have to assume that Ivelisse gets knocked out next week, and if for some reason they knock out TWO people, then that other person is either Eric or Christina. This probably means that AJ gets knocked out instead, the way my predictions have been going, ha ha.
