It'll be do you chop Pete's foot or does he do it himself. He knows it works in some conditions so he won't leave it no matter what you do.
One of the options will probably be to kill a character, there's been one of those in every episode so far (Ep1 had Carley/Doug, ep2 had Larry, Danny, Andy, ep3 had Duck, ep4 had Ben, ep5 had Lee and ep6 had Sam and Nick/Pete)
It looks like Troy is in the Amid The Ruins slide, so a choice might be to let him come with you (he does look sort of sad in that alleged leaked image and he's sent to give a message to the cabin so I guess he's Carver's reluctant bitch or something. Maybe he betrays Carver's group because he didn't realise Rebecca was pregnant (by him probably). This would probably have a knock on effect to Alvin, letting Troy come would make Alvin dislike you.
