Hannah is pretty well versed in her abilities, and I think the powers that be keep a tight leash on her to prevent her from getting any better (and trying to hack her way out). She works at the Facility, so they're likely to run into each other somehow, if you're interested.
Hannah doesn't know if she wants to be adopted, but friends are cool. I think they could get along well. She thinks her powers are hella cool, too.
Quentin would probably remind Hannah of an old 'friend' due to his conspiracy theory ideas. So, she would be interested in hearing more from him. She doesn't really care if he's watching her, she'd probably make it awkward on purpose and try to flirt. But she gets being suspicious, so she won't take it personal.
Hannah says 'what up' to Bart and would be friendly to him.
