personally, i feel that deleted scenes are only canon if you want them to be. especially when they haven't cgi'ed up the narnians yet!

god. peter would be the worst doctor ever. can't you just see it? "can you feel your legs?" "I CAN FEEL THE BLINDING PAIN." "good, you're good to go. come back when you can't feel anything!"

...god, i must be tired, i just wrote in a peter/susan/edmund puppypile. *squints*
