Arya left Clegane to die in agony. I don't see them breaking bread together anytime soon.
However, there is a young man whom we haven't seen for some time. He used to be an accomplished blacksmith and escaped from the Red witch with the help of Davos. I'm hoping he makes a return - possible with Arya since they were friends/love interests. That would finally unite the Baratheon and Stark families creating a massive powerhouse.
