'The Walking Dead' Season 4: Carol had no other decision, Melissa McBride saysAdd to Favorites | The Walking Dead
She continues, "I don't think there was really any other option. There's a lot of nature vs. nurture going on in this episode to look at. As much as it broke Carol's heart to have to do this and to realize this had to be done, when they were walking toward the flowers in that scene and Lizzie says, 'You're mad at me and I'm sorry.' You'd think she'd be sorry for stabbing her sister to death but instead she's sorry for pointing a gun at her and she just doesn't get it."
At least there was some good that came out of Season 4, episode 14. Carol finally confessed to Tyreese that she was the one who killed his girlfriend Karen, and Tyreese forgave her for it. According to McBride, this is a new start for the two.
"They trust each other 100 percent now. That was one of the reasons why it was so important for Carol to confess. She knew that she had to be able to trust the people she's with," McBride says. "He didn't kill her. Carol and Tyreese have bonded incredibly over this tragic experience and, as far as they know, the only two people. The only way to move forward is to be able to trust whomever you're with 100 percent."
"The ability to fight isn't a one-size fits all; everybody is different. Thematically, there's a lot said about change," she says. "The world will change you; but you have to adapt or die. It's about hanging on to that part of yourself: You can change but don't lose yourself."
Only two episodes of "The Walking Dead" Season 4 remain. The series airs Sundays on AMC at 9 p.m. ET/PT.
