Can you guess what it is? Harry/Voldemort? No. Harry/Snape? No. Harry/Snow White? Still no.

HARRY POTTER/HELENA RAVENCLAW!
Surprised eh?
This is actually a great ship. Helena(the grey lady) is wise and can teach Harry a lot of things. While Harry can visit her and help her survive loneliness.
BUT, Harry is not mah favorite person to ship with Ms. Ravenclaw.
