'The Walking Dead' star Christine Evangelista weighs in on Sherry's sudden exit

Warning: Spoilers ahead if you haven't caught up with "The Walking Dead."

Fans are still processing the sudden departure of Sherry from last week's episode of AMC's "The Walking Dead," but the star behind the role, Christine Evangelista, says she expected that her time on the zombie show was limited.

Sherry was Dwight's (Austin Amelio) ex-wife and later, one of murderous Negan's (Jeffrey Dean Morgan) many reluctant wives. Despite the danger, she was kind to Daryl (Norman Reedus) and helped him escape from Negan. After that, Evangelista said she began preparing herself to leave the show.

"I knew from earlier in the season that she was the one that helped Daryl," Evangelista told Business Insider at an NBC Universal event on Thursday. "So I knew that her time was limited. I was curious as to what she was going to do next. Sherry is always a step ahead in some ways. She always has some sort of plan. And I think that once Negan found out that she's the one that let Daryl out, which I'm sure he would've, she would've been dead. So I think she had no choice but to go."

Sherry escaped from the Sanctuary, but not before leaving Dwight a harsh, yet heartfelt, goodbye letter. The show seems to leave the door open for her coming back.

"I mean it was a sad letter that she wrote him, but she's a badass," Evangelista said. "She's running right now. She's doing her thing. I have a lot of faith in her."

Fans of Evangelista don't have to wait long to see her on TV again. She stars on the new E! drama "The Arrangement," in which she plays an up-and-coming actress who's offered a wedding contract to a famous Hollywood leading man, who's played by former "Dallas" reboot and "Desperate Housewives" star Josh Henderson.

"It happened within a couple of days," the actress said of going from "The Walking Dead" to working on "The Arrangement," which premieres Sunday at 10 p.m. "I think I literally went from one set to the other, which was awesome. You know, it's a completely different world. It was definitely a sharp transition."
