Those who thought the first half of The Walking Dead's sixth season was a bit too tame will be in for a major change of pace when the season's back half picks up again this Sunday.  

Glenn & Maggie's Reunion May Not Be A Happy One

In an interview with Entertainment Weekly, Andrew Lincoln opened up on the next eight episodes, which he called terrifying and dark, promising that things were going to not only pick up action wise, but that they would be like nothing fans have seen before.  

"We do realize very quickly in the returning episode that it's almost like the end of a chapter. Something happens. Rick learns a lot about himself in this episode," he said. "What I will say is that the pace quickens a lot in the back eight. It jumps up a gear, maybe two gears, and we move very, very quickly. A lot of things happen in quick succession that propel us towards a very thrilling finale...It's absolute mayhem. I think it's going to scare some people."

He also teased that something big would happen in episode nine--the one that kicks off the back half--and revealed that it could epically change things for his character's perspective.  

"I think you'll see there's a marked change in Rick as a result of what happens in episode 9," he said. "It's one of those watershed moments that happens. And as a result he learns something vital about being a leader. And yet again, he changes. And he develops a new way of leading. And that could be said for the back 8, in that it turns very dark." 

The Walking Dead returns Sunday, Feb. 14 at 9 p.m. on AMC.
