I really see no other option than playing as her this time. I cant imagine having a new protagonist befriend her like Lee did right after the events of this game. It wouldnt seem right at all. I would also not like to see a brand new set of people or anything. Im way too invested in the survivors of this game to just forget about them and move on to a new group so basically, either i play as Clementine next game or i dont play.
i read an interesting theory that season 2 would star the people in the field at the end of season one, and would show how they would up on that side, then season 3 would star as clem.
That wouldn't be too bad, although those two characters didn't look very interesting honestly, and the way they left us hanging at the end, they owe us some closure. It was just a terrible way to end things, especially if they aren't planning to continue where they left off.
I agree with Lord and Savior. They should leave Clem alone. Her story as well as Lee's has been told. Usually they only ruin things by trying to further it. Incidentally, it is why I love American Horror Story.
