Castle season 8 Nathan Fillion Reacts 'The Walking Dead' Season 6 Cliffhanger, Negan's Victim

The internet is still buzzing about the shocking finale of The Walking Dead Season 6, which ended with a lengthy monologue from Jeffrey Dean Morgan's Negan and a haunting POV shot of his victim. But whose point of view did we see in the final seconds of "Last Day on Earth?" Fans have several speculations whether it is Glenn (Steven Yeun), Daryl (Norman Reedus) or Rick (Andrew Lincoln). However, Castle star Nathan Fillion appears to have the best (and possibly correct) answer!

The Con Men actor tweeted about the TWD season finale and was even helpful enough to add a "spoiler" warning. Fillion declared that Negan certainly took his time in choosing his victim but in the end, he was not expecting the comic book villain's choice.

Once again, if you haven't seen the season finale, this is your FINAL warning to avoid any spoilers.

#WalkingDead spoiler alert.

After all that trouble to pick someone, Negan chooses the camera man? Didn't see that coming.

Who would have thought that the hapless camera man would meet his end in Season 6? The poor guy has survived hordes of walkers, the prison, the Governor and even Daryl's blood splatter but still ends up being chosen by Negan as the one person who deserves an epic whacking from Lucille.

In case you missed the untimely death of the TWD camera man, you can watch it again below.

All kidding aside, Lincoln has previously spoken up about the last seconds of "Last Day on Earth," stating it was an excellent way to end Season 6.

"It was like an assault on the audience almost, the way that we go to their POV," he told ComicBook.com. "It's an incredibly dynamic way to do it."

The Walking Dead Season 6 will be available in Blu-Ray, DVD and Digital HD on August 23. The seventh season is expected to air on AMC by October.
