Tyler James Williams Says He Knows Who Negan Killed -- And Reveals One Problem with the "Walking Dead" Finale!

"I don't know why it was that big of a deal," the actor tells toofab, after his comments to EW on Monday, where he still kept the identity of Lucille's victim a secret.

"They're all going back to work in like a week. I'm sure it's not just the cast, it's like crew also, like 200 people know," he adds. "I knew, I didn't think it was that far out of the realm of understanding!"

So far, everyone from the cast -- with the exception of Norman Reedus -- have claimed ignorance over who was offed ... so, how does someone who was killed off in Season 5 know what happened?!

"It was just kind of said in passing [with his former costars]. It was just like regular conversation, I think we were talking more about how early they were going back and it was said in passing," Williams reveals.

When asked whether he was bummed they blew the surprise for him, Tyler says it doesn't bother him at all.

"As an actor, it's less to me about the surprise of it all than seeing the execution of it all," he explains. "I like to watch great actors. I'm the type of guy, you could tell me what a movie's about and I'll still go watch it to see it executed. You could have a great concept for a movie and somebody gets in there, jacks it up and it's a terrible film. At the end of the day, I'm still gonna watch."

Fans of the series went crazy after the finale ended without revealing who Negan killed, with many of the "TWD" faithful claiming the show had jumped the shark by teasing something all season and not paying it off. Williams says he had a feeling that'd happen -- but that's not his problem with how it ended and the ensuing reaction.

"I knew about the cliffhanger, which I was like, people aren't gonna be happy," he tells us. "I got a heads up. The big thing about the cliffhanger, the one thing I wasn't crazy about with the cliffhanger and how people responded to it was Jeffrey Dean Morgan, he KILLED that monologue but not that many people were talking about it, they were talking about the cliffhanger. He absolutely ripped that in half. I understand that's kind of annoying, but that's what the show does anyway. Can we talk about how amazing he was?! Understand the master class that he put on in that."

Williams' character, Noah, met a particularly grisly end after getting trapped with some hungry walkers in a revolving door. But, he tells us, he still has a fierce loyalty to his former costars ... and won't be spilling any secrets anytime soon!

"I don't have to speak ambiguously [since his exit]," he explains. "I'm sure if I was actually still on the show now, they'd all be like, 'Why did you say that you knew?' I'm still gonna hold onto it, I'm still part of the family ... and the integrity of the show, I would never compromise the integrity of a show like that. It's still good to everyone at the end of the day, it takes care of a lot of people and I'm still on of its biggest cheerleaders."

As for his memorable death, he says he's "forever in their debt" for giving him a gruesome sendoff.

Williams is currently starring on "Criminal Minds: Beyond Borders" and "RePlay," a new series launching today on go90. On the digital series, Tyler plays BFF to a struggling musician who's stuck repeating her disastrous 25th birthday.

"'Re-Play' is like a modern day 'Groundhog's Day,' except in this one, the people around her begin to realize the world is also repeating," Williams says. "It's one of those shows that's just really fun. I had a great time shooting it, watching this character devolve into the situation and try to cope with figuring out who his real self is."

"We're going directly to the consumer, there is no middle man," he says of distributing the show via an app. "You don't have to be sitting in front of your television at this time, it's on your phone, which you have with you at all times. If you want to watch the show, it'll be there."

He adds that working on the series is "very similar" to his other TV work. "The only difference is the roll out," he explains. "Everything is shot professionally, its like any other show."
