Oh don't worry about that. Hope does occasionally need to be taken back a peg or two, especially when she starts focusing in on something to the 'nth degree. And the real reason for acting like she did was the fact that seeing Faust brought back some very, very nasty memories. No one is going to behave or react well when dealing with that kind of horror.
Like I posted in Hope's character thread, she can be rather intense, especially when dealing with guys like Faust and White Knight. That can be rather.... offputting to some one who isn't used to that sort of thing.
