Well Rick is out of question, Carl and Megie too. I don't believe he would chose Sasha as wictim of choice either. I mean, hitting a women with baseball bat? Nahhhhh...
Daril was wounded already, maybe him, but I dubt.
I'd put my bets on Abraham too. Anyone tried to check camera angle? Or find some info which actor is missing in season 7?
Most people fail in life not because they aim too high and miss, but because they aim too low and hit.
