A tricky opponent
On Fex's execution day, Kazz had seen the power of the Boneclaw, back then, it was able to go toe to toe with her father, until eventually its energy was running low. She knew the Boneclaw was an incredibly strong familiar that not many vampires would be able to handle.
However, Quinn was someone who had even bested her father in a fight. Yet, for some reason, the Boneclaw had attempted to challenge Quinn now. When he was possibly at his strongest.
'Something had to have changed in the Boneclaw's reasoning, is Quinn's desire from before no longer matching up with its, or did something happen to the Boneclaw to make it feel this way?'
Finding out the answer to the question wouldn't help the situation. What she needed to do right now was decide if she was going to help Quinn or not.
