Marietta Edgecombe and Bill Weasley
Bill Weasley had heard all about Marietta Edgecombe from the Hogwarts brood at the Burrow, particularly Ginny who had seemed very angry when she starting talking about her and the betrayal that she had committed. Bill couldn't help but roll his eyes, it had all worked out fine in the end so what was the problem? Two years later he encountered Marietta Edgecombe, working with her at the final battle after they had all been split into teams. As he saw her fall to the floor from a green killing curse, she didn't seem like a traitor. She was fighting on the right side, on their side. Just a kid who had made a wrong decision, a kid caught up in this war. Who could blame her?
