Warning: Spoilers for "The Walking Dead"

AMC's "The Walking Dead" has a tendency to produce bloated and lethargic season finales. That trend held true for this weekend's season six finale as the arrival of Jeffrey Dean Morgan's Negan was undercut by a repetitive, nonsensical and poorly structured episode that managed to inflame the entirety of the Internet.

What fans most struggled with was the soap opera-like cliffhanger about whom Negan killed at the episode's conclusion. While frustrating, perhaps it will come as some comfort to know that not even the star of the show knows who Negan dispatched.

"We made a pact because it was such an intense two days [filming Negan's scene] when we shot it to keep our heads down and let it play out as it was intended," Andrew Lincoln said in a recent interview. "I have theories and thoughts but I'm not going to go on record and tell them quite yet! Maybe sometime midseason next year! All I know is we haven't fully shot the scene yet and I'll only know when the scene is completed how Rick feels. One of us is going to get it and that's going to be terrible personally and professionally. We made a deal when we got down on our knees that we wouldn't talk about it."

Actors on "The Walking Dead" often aren't given the full details of certain storylines and many of them choose to avoid the comic book source material to remain uninformed. Chandler Riggs, who plays Carl, admitted that he also is unaware who Negan killed in the finale.

However, many view this as the most pivotal scene in the comic books (Spoiler Alert: Glenn is the one who is killed there), and the cliffhanger ending really subverted what should have been a major turning point in the series. We would assume that the cast would be just as curious as the audience, but apparently that isn't the case.

Then again, Lincoln and the rest of the cast probably knew they would be bombarded with questions between now and season seven. Publicly announcing that you don't know who got whacked is a good way to deflect some of that oncoming heat and attention.

Lincoln may not know who got killed, but he did admit that his character is going to feel incredibly guilty and responsible. Rick is going to feel as if it is his fault because he is the one who underestimated The Saviors from the get go. Despite the flaws of the season finale, that does sound like an interesting storyline to explore.

"The Walking Dead" will return for a seventh season in October.
