You didn't say, but it is easy to figure it out.
It is if you remember that certain scene from the first episode, and remember who couldn't get picked because another tribe had already claimed him/her.
I'm loving this season. Tom and Ian aren't the run-of-the-mill Survivors, and it seems - at least, so far - that Burnett will let the game play out with no switches or regroupings to benefit the losing tribe.
