A quick look at the books in the room revealed to Zoro that it was, indeed, a doctor's office. Living in close quarters with Chopper and his books (and, more-or-less being on the receiving end of the treatments found in them), Zoro found that medical jargon sounded the same no matter where you were. And even if they weren't using their fancy words, doctors did all tend to sound alike anyway: don't stab yourself in the gut this, don't lose five liters of blood that. Feh.
But speaking of doctors... he noticed that Mousse was still injured. The boy probably healed slow or something.
"Hey, that from that first night?" Zoro indicated to Mousse's arm with a tilt of his chin.
