-Harry Potter and The Umbrella Academy crossover- Regulus Black and Hope Potter hated each other, it was simple, they were enemies. When there are dvds sent from an unknown person telling them to watch a show in which Hope Potter is actually Hope Hargreeves and Regulus Black is actually Five Hargreeves, who just happen to like each other. What happens when the doppelgängers meet? Maybe Regulus and Hope hated each other so much that they didn't hate each other at all.
