Which OC prefers to keep their issues to themselves?

Several, but probably the worst affected is in fact Kaya Cade.  In the first story (The Little Queen), what we learn about her is that she was once friends with Jennifer, but they grew apart as Jen became increasingly withdrawn and Kaya joined another clique and became a bit of a bully, only much later starting to realise that most the people she was hanging out with were assholes.  More importantly, we also do see that she has a not exactly good relationship with her father (she later admits that it was partly jeaslously of how close Jen was to her parents that made Kay turn on her).  But the thing is that Kay never really talks about any issues she has and this occasionally makes her act out in ways that are either aggressive or self destructive – something we’ll see a little bit more of in the next story.
