[Hours pass before Cu finally pokes his head into Diarmuids room - setting and splinting Shirou's leg, patching up the knife wound, and making sure Archer didn't try to kill him again (because once a day is enough, and you're going to have to clean the blood up) takes time, and even then he's not entirely sure how to handle this.]

...so. What happened?

["Shirou was stupid" is a given, but he's fairly sure the kid didn't deserve THAT much]
