Ah, Sash... I don't think they can trust him as far as they can throw him. I think he meant what he said. I also think that if he's going to lie, he needs to get better at it. When Jeff asked if he would hand the idol over, he should have immediately responded in the affirmative (and then he could have thrown in the caveat that there was no reason to at that point). And I'm still convinced that he is gay. Not that means anything other than he was a liar from the start.
At Nay's behavior on the preview. Not that I expected less, but I hope it backfires big time.
