I am so looking forward to this, like you don't even know! The 13th of October cannot get here fast enough for me B].
As for who I think will die first, I really don't know at this point. It can really be anyone(other than Daryl and Michonne ofc ;D). I am kind of thinking Sasha will get axed early, but I am still skeptical about that because she was promoted to main cast. I think we will see a few Woodbury survivors go first though.
