Fear tilts his head to the side for a moment, recalculating the encounter. Bruce's reply isn't entirely what he was expecting, and if he had a fraction more empathy or social graces, he'd be able to understand the implications of this and try to diffuse it- but he doesn't.

"Of course it is. I came to ask you about this facility of yours- it's quite the hotspot for emotion in the city."
