When Arya is blind and doing her duties in the temple, she finds a dead young man with curly hair in front of the Stranger's shrine (making him most likely Westerosi) and he has 3 Golden Dragons (I think) on him, making him either a noble or else a merchant. I'm totally guessing on that, but GRRM is not known for putting subtly into his books for no purpose, so I kind of think this dead guy is important. I can't imagine who it could be though. The only person that comes to mind that's MIA and fits the description is Edric Storm. But I can't imagine why he'd have died, gone to the temple and then be found by Blind-Arya of all people. Unless she wears his face (possibly thinking it's Gendry) to return to Westeros. That would be pretty messed up though.
