I'm sure Clem will return in some fashion. She's very popular as a character, and I don't see the point in the end-credits bonus scene if they weren't going to elaborate on it. I just don't know how big her role will be in season 2. Will she be a main character, or will you run into her later on?
In any case, I don't think you will be her hands-on caretaker this time around, as Lee had already done a great job teaching her to be a survivor throughout season 1, with handling Lee's death being her final lesson. After leaving Lee, she is completely alone, at least for a while, and has no other choice but to toughen up. If anything, maybe she will teach our new protagonist a few tricks.
I'd actually prefer not to be her caretaker in season 2 anyway, since you could never top the Lee/Clem relationship from the first season, and trying to plug in some other guy to that same role wouldn't be as great.
