For the next several months, there will be one question on the minds of The Walking Dead fans: who did Negan (Jeffrey Dean Morgan) kill? After almost all of Season 6 lead up to our first glimpse at this iconic villain in the season finale, we finally got to see the Saviors' leader in the flesh. Just like his introduction in the comic, Negan uses his baseball bat wrapped in barbed wire, dubbed Lucille, to kill one of the Alexandrians in the finale's last moments. But the victim's identity was hidden from the audience. ComicBook.com recently spoke to series star Andrew Lincoln, who teased that the entire cast made a pact not to discuss the victim's identity.

"We kind of made a pact with each other, just because personally and professionally one of us is going. These people are lovely, dear friends. Including myself one of us is gonna get it. We all just made a pact not to discuss it. It's upsetting. It's too precious. There are certain things that become sacred on set and I'm afraid, I'm one of these people going, 'I can't talk about it.' Every time we've lost somebody on the show they've been instrumental in story telling. It's the same thing. We lock up shop. We linked arms, got on our knees, and said, 'You know what? Let's not discuss this. It's painful. No apologies.'"

As it turns out, though, the actors themselves made this pact without knowing who the victim is. Greg Nicotero, who directed last week's season finale, revealed earlier this week that none of the cast members, except Jeffrey Dean Morgan, were even on the set during that scene's final moments, when Negan bashed in the skull of this mystery character. Robert Kirkman teased that this character is "beloved by everyone," but that doesn't exactly narrow down the field too much.

In Robert Kirkman's comics, Negan is introduced in a similar fashion, after his Saviors laid a trap for Rick and his crew. In the comics, Negan kills Glenn Rhee (Steven Yeun), who had his own unique brush with death earlier this season. After Nicholas (Michael Traynor) killed himself, Glenn was pulled into a group of zombies, and it appeared that he may have been killed off. We found out just a few episodes later that Glenn did actually survive, eventually making his way back to Alexandria in the mid-season finale.

In the final scene, when Negan finally chooses his victim, he says that if anybody moves, the Saviors should rip Carl's other eye out and feed it to his father. Of course, this would seemingly eliminate both Carl and Rick from Negan's wrath, since Rick wouldn't be able to "eat" Carl's eye, and Carl wouldn't need his good eye removed as punishment if he was dead, but there are still so many other Alexandrians to choose from. Do you have any theories about who Negan killed in The Walking Dead?
