It's not so much that I dislike Nico or anything but she's seems like she needs to sort some things out pre-any kind of relationship. While I can still see some small issues in Xavin/Karolina a re-reading reminded me how dickish everyone treated Xavin(granted some of it was out of concern for Karolina) and how the two of them actually did seem to be getting along nicely until Moore intervened. :\
