Yeah, I doubt it. You can tell on the last page it's not Karin or Ino. So who else has medical knowledge? Kabuto. You see the "mysterious figure" is bare-footed so that means it can't be any of the medical ninjas that's fighting on their side. Kabuto is going to come back, give us a sob-story about how much he wants to suck Orochi's dick and then he'll heal him.
