@Impero: Well, we all know how this has played out with Gambler and Cass. She ended up cutting all ties (or trying to) because he didn't want to be saved.
Quintus is a bit more dangerous - he's the equivalent of a zealot. He believes his cause is the righteous cause. I doubt she'll be able to sway him. I could see her dying/being severely injured due to his actions as a way for that to happen - but in all likelihood, it would only drive him darker.
