Now that we know it could be a princess it could well be Arya too surely? There was certainly a lot of salt around when she was reborn as a quasi-faceless-girl. I’m sure we could find some smoke too if we looked for it. Do we know for a fact that she did not come back from the dead, where by any normal standard of mortality she should’ve died there in Braavos?
Also some cases to be made for Sansa and Bran and even Sam Tarly (that’s a badass sword you got there Sam)
