"Then we need to find out what she knows." The Bat was stating the obvious, but the person within wanted to kick someone for having to wait. Having to wait until the witch woke back up. The Bat nodded slightly, having made a decision.
"I may have somewhere to hold her." The Bat had money, or access to it anyway. Money and real estate. "Unless you have something." The Bat could interrogate, but the person in the armor wasn't a big fan of it. Beating answers out of a suspect was doable, very doable.
"Will she talk easily? What will we need otherwise?" Thugs were easy, witches might not be so easy.
