He isn't allowed to wear stark house colors because he is in the Knights Watch and they dedicate their lives to that and stuff.bro you can consider him whatever you want. He isnt allowed to wear stark house symbol was my own point, he's still stark blood and brother to arya and bran, and rickon i guess? I cant wait to see what happens with him
He is stark blood, his father just banged some whore. I believe that he is the natural king of the north now, but I could be wrong. Pretty sure he is though since Robb died.
