There is a transition in episode S06E08 where Beric tells the Hound that he can still help and it’s not too late for him, and then it transitions to Arya laying in bed after being stabbed by Waif. Maybe it is a foreshadowing and the Hound will save/help Arya in season 8. Maybe even sacrificing himself… But before that he has to kill the Mountain using a flaming sword!
