"Kinda don't think I'm gonna forget." Not that he thinks she means that, exactly - but since he really started seeing her this has been there. How she made him happy just being around her and he wasn't sure how or why, but not only that. How she was with other people. How she was with her family, especially Hershel after he lost the leg, how she was with Carl, how she was with Judith and Carol, doing whatever little thing she could to make everyone's lives a little better. Easier. Happier. She did it quietly. Not asking for anything in return. Just... doing it.

He wonders how many other people noticed it.

It's part of who she is, and he still can't really understand why she's chosen to focus that nature on him.

"Never gonna let you forget."
