Conan heard the creak, and rolled his eyes. Something had to have caused the door to open, since the Mansion doens't usually have that many indoor winds. Casually went through the door opposite the one he'd come in by, exiting into another hall. He can hear faint sounds behind him, but doesn't wait - it's not his job to make sure the one after him's keeping up, after all.

(Ah, that helps. Kind of - I don't know the Batman verse so well. But I'll try to keep all that in mind ^^)
