I don't know, maybe something stupid about money?
What happened to Xander?
Well, I just think that maybe he's not as good as Bianca thought, so he become traitor or big-mouth? I think it might be related on what happened to her father, maybe?
And what happened to her brother?
Well, I hope he was a big brother which every sister little sister asked for and because he loved Bianca so much, he tried to protect her and ended up, well, you know...dead. And on my complicated mind, I think it might be related on what happened on her father and Xander.
Anyway, it's your story, I already love every chapter that you wrote so far, so whatever happened next I hope it's refreshing and open-minded, and not so much cliche,
