"That's... wow, I mean you hear about Gotham, but I didn't know it could be like that." It was a little too much to think about, she knew the reputation Gotham had of course, she lived there, but it was something else to hear what Harley was saying about it, what it was like for her. Even from Harley's perspective.
Now that was a little less surprising when Harley told him what she was reading, it was strangely fitting. But well a Library that was an idea, one that was promptly gone from her head when another shot rang out, but no one was shot this time. So that was... something.
She flinched though, before she smiled when Harley turned back to her, she preferred shooting and no one shot to the other way that could turn out.
"Friends can be hard," She agreed, she didn't know what to do about the Joker though, how to reassure her or anything like that. But friends she kind of knew, and they were hard, guys though - they were a whole other ballgame, complicated and strange, and sometimes murderers. "I guess we've just gotta give it a little time, you know? Let things happen and see where they take us."
