So to those of who have been watching The Walking Dead, obviously the season finale was shocking to people who didn't realize what was going to happen. So who do you think Negan killed? After the preview, my bet is on Maggie. You may wonder why I assume this, and that's because of the blood on Rick's cheek (Maggie had been the one to his right), and the fact that there was a ring in the smashed remnants of whoever had been killed. Because of how close Rick was to Maggie, given that she had been with them for so long, and the fact that she honestly looked like she was in pretty horrible shape to begin with. They might have made Negan even more sadistic in the show than the comics, so he could very well not care which gender he kills.
But that's just my assumptions that I gathered from the preview. I would love to see if anyone else on here watches it, what your thoughts are!
