'The Walking Dead' Season 6 SPOILERS: [WATCH] "Last Day on Earth" Finale Moment [VIDEO]

The final episode of The Walking Dead Season 6 definitely had fans going crazy over the debut of Negan. Although "Last Day on Earth" buzzed with nail-biting tension over the impending arrival of the comic book villain and were rewarded with an excellent performance from Jeffrey Dean Morgan, viewers were almost immediately left with one very important question: Who did Negan just kill? Now you can relive the final moment over and over again to try and figure out just what happened before the screen went black!

The final scene of TWD Season 6 episode 16 has just become available online, just in case fans want to keep guessing who Negan picked to use as "punishment" for Rick's (Andrew Lincoln) Savior massacre. The last minutes are unbelievably tense as the villain plays "eenie meenie miney moe" with the group, pointing Lucille at the kneeling survivors. In the end, he doesn't waste too much time taking care of business, bludgeoning his victim with the barbed wire-covered baseball bat.

But who exactly was on the receiving end of Negan's blows? Some fans believe it may be Steven Yeun's Glenn, as depicted in the comic books. The villain even joyously says his trademark lines in the comics, exclaiming on how Glenn is "taking it like a champ" after the character tries to get up.

However, viewers shouldn't be too quick in jumping into conclusions about Glenn's death. After all, the AMC show has already changed things around by letting Denise (Merritt Wever) receive an arrow through the head instead of Abraham (Michael Cudlitz) in the fourteenth episode. There is still a possibility that a different character had been killed off in "Last Day on Earth."

Who do you think was Negan's victim in the TWD season finale? Let us know in the comments.
