Man. Mitsuboshi has got to be the least effective accomplice ever. Not only was he being super obvious, he nearly lead Asahi right to Shio! Though I have to wonder, seeing as he was basically repeating what Sato told him to say, maybe he was set up and Sato wanted him to be caught.
Sato's friend screwed up pretty bad too. Darn japanese cameras and their required shutter sounds. Though I doubt Sato's going to do anything while Shio's there to witness it. She might still have a chance to escape.
