There IS reason to hope Matt! Vanessa may be many things, but Buddy is her adoptive brother, and for all that she may be, she cares about Buddy and his well being. And that is something that nobody can take away. Not even Miles Mayhem!
Sounds like Vanessa came close to telling Buddy the truth about herself. And if he ever does find out, there is going to be a LOT of both remenissing and yelling on both sides!
Sounds like Vannessa is taking this very hard! She just found out that Buddy is in the hospital, and that Rax wanted to take her out! Vanessa needs to keep low, and think things out. And if that means surrendering to Buddy, then so be it!
