Hex

House knew where Hex worked. Fin had mentioned it, and though House wasn't thrilled at the idea of walking into a bar with a bunch of vampires (yes, really), and wasn't really thrilled about the idea of seeing Hex either, after a few days of remote coordination over Fin's disappearance he decided that they should probably speak in person.

And surrounding himself by alcohol seemed like a good time to do it.

He walked in, getting a few odd looks, and - was that a drag queen at the piano? That wasn't a vampire thing, was it?

He walked to the bar and sat down.
