I'm not 100% sure if my timeline is correct on this but I think you're right that they seemed to fall out when Chessie started dating Matt and basically being obsessed with him while Step was either breaking up with Luke or was relatively newly single. Totally the same that I'm annoyed at myself that I'm so into why they fell out hahaI think it was when Chessie got with Matt, Steph no longer there. They had that drunken reunion last year but never spoke of it again. Hazel and Zanna used to be close, then Steph and Zanna paired up, as did Chessie and Hazel. I think Rhi stayed with Chessie. I hate how much I know about all this and how interested I am, but is the only reason I keep an eye on it all
