WARNING: This article contains spoilers from season 4 of The Walking Dead.

The second half of season 4 of The Walking Dead premieres on AMC on Feb. 9. In order to fully appreciate the last half of the season, star Andrew Lincoln is taking a walk down memory lane by examining episodes 1-8 of season 4.

"I'm really excited about the back 8 episodes," Lincoln told Entertainment Weekly. "I think there's a different tone to the back 8, and I think you're going to see a lot of characters that you haven't seen under the microscope as much all have their chance to shine."

Lincoln's Rick Grimes saw one of the biggest transformations this season, and the results will show with Feb. 9's episode.

"Man, he never gets a break," Lincoln said. "It's not an easy guy to play ... I do think that Rick is in a very low ebb, and I think physically, in episode 9, you'll see a man who is frightened for the first time in a long, long time ... He's very, very weak and that makes him belligerent and aggressively challenging towards his son because he's scared ... He's lost. Mentally he doesn't quite know where to begin because he's just seeing his home demolished. He's in the worst place he's been."
