I'd definitely say a Pauline-centered group will form, with Mark and Helen in the mix for sure. I think Pauline and her friends will be the comfortable, Insider-ish group of the series. (I'm not saying they'll be nasty, etc, but Pauline has already been quite hurtful about Chris, the new one, and I could just see them getting smug together).
I can also see Christopher and Ashleigh becoming close, they've been talking to each other and seem to get along. If an antagonistic group does form, I'd like these two to be opposed to it, they seem sweet and good-natured right now (well, apart from Christopher loving Katie Hopkins, but I'll let that slide

). But, yeah, just some early predictions of mine.
Aaah, I love these early days when we predict who'll befriend who, etc.
