If you have to go out on "The Walking Dead," go out in style.

When the AMC zombie drama returns to finish its eighth season on Feb. 25, it'll be the last episode for Carl (Chandler Riggs). He was bitten by a walker in the midseason finale, and since then, producers and cast members have acknowledged that this is definitely the end for the troubled teen.

Andrew Lincoln, who plays Carl's dad Rick Grimes, said at least Carl's death provides "catharsis" for everybody.

"I'm not going to lie to you, that was sad," he noted. "The beautiful thing is it's what we rarely do in our show — we actually give the opportunity for a goodbye. It was unusual in that regard. Usually, things happen and people are ripped from you in this world that we inhabit. Thankfully, there was some sense of catharsis on this one, because we got to leave it all out on the screen. I thought Chandler did a remarkable job, as he always has done, but particularly in this episode."

But Carl's death will serve a purpose in the story, propelling Rick to new emotional places. "There is a balancing of the scales in Rick's life that happens in the back eight episodes," Lincoln teased. "A lot of it is because of what is said in episode 9, by his son."

"The Walking Dead" returns Sunday, Feb. 25 on AMC.
