Everyone Is Freaking Out About The End Of Sunday's Episode Of 'The Walking Dead'

Warning: There are MAJOR spoilers ahead.

Sunday night's episode of "The Walking Dead" just concluded with a huge surprise.

After Rick and the prison crew fight off walkers at the prison and a debilitating disease, you'd think the gang would get a break. Nope! It looks e finally see that a major character will be returning next week.

Last chance to head back before spoilers.

The Governor is back!

We see actor David Morrissey lurking in the shadows of the prison before the episode fades to black. How long has he been there? What is he up to? Does he have an army ready to fight Rick and the prisonmates?

It's clear that no one saw this twist coming.
