I personally have seen enough of Molly, I never liked her character at all. And I know this has been said but I don't see how even someone who does free running etc, could scale walls with an ice pick. Plus when you first see her scaling that building through the telescope, bearing in mind she is miles away, and you look away for like a couple of seconds to talk to Kenny and then she is right in front of you!! I don't think that is very believable, and not many people have the strength to help fully grown men up buildings, fight off zombies and practically be that physically involved after not having much to eat due to there barely being any food about.
I know this is fiction but seriously... It seems too unrealistic! Her character was portrayed as being a lone wolf who would prefer to go it alone and she didn't seem to keen to stay around Lee and the group for too long as she probably lives by the rule of teammates get you killed. So I think we have seen enough of her. To me she wasn't a very likeable character and I didn't get very emotionally attached either, her sisters storyline wasn't that great compared to others and I think the could have taken a little bit more time to go deeper with her.... However she was one of those people who keeps themselves to themselves and she didn't really want to open up about anything.
So, no I do not want to see Molly in season 2 she wasn't a very likeable character and I could see why not many other people would like to see her again, and I'm pretty sure that protagonist is out of the question as her stupid free running like style is too unreal for me, it would be like assassins creed... And I don't think that is what I would like to see, I didn't enjoy the bit where you have to jump off the building as it was as it seemed stupid and not really that ... Epic I suppose (if they were trying to make lee badass then it wasn't working)
