Glenn & Abraham
As seen in: Season 7
The show reached an all-too familiar moment for comic readers at the end of Season 6, when Negan made his debut and chose a victim to bludgeon to death with his trusty baseball bat. At first, it seemed like the show would defy expectations by having Abraham be Negan's chosen target instead of Glenn. But that's what we get for thinking we can have nice things on this show, because then the sadistic villain decided to kill Glenn, too, just to hammer home his message.
