SPOILER WARNING: This article contains major spoilers for last night's episode of "The Walking Dead," "Thank You."

Last night, on "The Walking Dead," fans saw what appeared to be the demise of one of the show's oldest and most popular characters.

Glenn Rhee (Steven Yeun), one of the show's main characters since the first episode, seemed to meet his demise at the gnashing teeth and clawing fingers of a herd of walkers. To celebrate the characters storied history, Yahoo! Movies has compiled a video of Glenn's greatest -- and often goriest -- moments from his five-plus seasons on the hit AMC series.

While the scene on last night's episode looked fairly definitive, with organs getting ripped out of bodies and blood oozing everywhere, it was shot in such a way that leaves some wiggle room for Glenn's fate. Fans have theorized that what was shown being eviscerated may in fact have been Nicholas' body on top of Glenn's, and it's him who's getting torn apart -- thus giving Glenn time to escape.

"Walking Dead" showrunner Scott M. Gimple released a statement on the situation via AMC's post-show "Talking Dead," though it's deliberately vague as to the outcome:

In some way we will see Glenn -- some version of Glenn or parts of Glenn -- again. Either in flashback or the current story to help complete the story.

Glenn's future on "The Walking Dead" has been an open question for fans of the comic books since -- major "Walking Dead" comic book spoilers follow -- the character was killed off in 2012's issue #100 of the series by Robert Kirkman and Charlie Adlard. Things went down very differently in that scene than they did in tonight's episode of the TV series, and it's been proven in multiple instances that death in one "Walking Dead" medium doesn't guarantee death in another, but even if Glenn makes it out of the walker pit alive, fans may wonder if he's still on borrowed time.

"The Walking Dead" airs Sundays at 9 p.m. on AMC.
