Fed up with always feeling one step behind, Quinn is determined to find out who is trying to annihilate all of Bullard's team. Only the trail takes him to Izzie, Bullard's niece. The team knows the saboteur was someone close to Bullard, and Izzie had had a hell of a fight with Bullard the last time they spoke. But how involved was she in this plane crash? He didn't want to think badly of her, but, at this point in time, he was looking at everyone with suspicion.
Izzie is also suspicious of everyone. She's been to hell and back, all because she was stubborn and angry at Bullard, but she'd never do anything to hurt him. Not knowing anything about the last few months' trials, she's horrified to find out why Quinn sought her out. Then he's horrified when he finds out what happened to her. Working on healing her own soul, she's desperate to help Quinn find out who attacked the team and potentially killed her uncle.
If she can do anything to help, she will, particularly if it gives her a chance to make amends to the one man who's always been there for her.
