There are a hundred things in Peter's voice and face that are making Edmund uncomfortable. An apology for one. An apology for the last year and the way Peter's been acting, an apology for taking Edmund for granted. An apology for the raid, and the witch, and for Peter's imminent death. They're all there, just below the surface, more urgent because of the pain and adrenaline. All year Peter's been restraining himself, trying not to say all those things he hasn't said since they came back from the Professor's, but Edmund's seen them, trying to break through this cold, gray exterior, and now, of all times, they're probably going to get the best of him. He's going to thank Edmund in public.

And that is something Edmund cannot allow, especially because his opening "Ed…" sounds so much like a goodbye, a goodbye Edmund knows they probably need to have, and one they probably will never get, but a goodbye, a real, final goodbye, and the idea that Peter think he's going to die makes his head turn and his stomach spin, and he thinks, in that irrational way he can remember thinking when he was little and scared of thunderstorms, if he just pretends with everything he has and denies it with everything he is, then maybe Peter will live and Caspian will become king and they can all just go home.

So he snaps Peter's arm back into his socket without a word as Peter groans and rubs his shoulder like he's never been in more pain in his entire life. "Save it for later," he snaps, so sharply Peter can't even say anything, though upon further examination, Edmund realizes that this might be because of the state of Peter –in enough pain that normal vocal processes arenot performing at a level beyond an occasional garbled cry.

Edmund walks away from Peter to get some water and to retrieve his brother's helmet. He can see Miraz talking to the two men who want him dead. They're conspiring, and Edmund watches them, trying to read their lips and avoid going back to Peter at all costs just so he can try to apologize again.

Or even worse –say goodbye.
