I think it'll be a completely new character for season 2

At least i really hope so and if any of our group make it to the end that they'll at least show up again at least once in the new season.
I know a lot of people won't like this idea, but say I think it'll be cool to have Ben as a main character and he'll be more mature and changed from the events in episode 5. I know that won't happen though because he can die

It'll be nice to have a teaser for the new season shown at the end of episode 5 too
Edit:
I really hope it won't be Molly, I just can't trust her at all. I'll have to wait for episode 5 to see whether I'm right about finding her fishy...
