Negan will only kill one. Just like his lackeys have said repeatedly throughout the season, they kill one straight off as an example to the rest. More only die if they fail to fall in line like the pegged suckers they are or if they stiff Negan of his half of their shit.

Second, naturally Trevor from GTA V is a natural fit for this show! Hopefully we see more of him, he's a perfect secondary bad guy to Negan's primary bad guy.

Third, I'm putting my guess in spoilers, just because I've read the comics and with such a powerful scene it was in the comics, no way in hell do they change it in the show, especially since his death has multiple ramifications for the group as a whole going forward.

Spoiler: show
