Nia tilted her head to the side thoughtfully. Luckily she'd read a bit about Harry Potter's life. "Things in the second wizarding war would have been very different," she answered softly as she raised her hand. "I mean, didn't Albus Dumbledore leave them all things in his will to help Harry on the road to defeating the Dark Lord. If they hadn't been friends, Harry wouldn't have necessarily had all the clues he needed. Or the knowledge, since wasn't Hermione the brainy prepared one?"

She bit her lip. "Oh, and there wouldn't have been a Dumbledore's army! Cos didn't Hermione and Ron persuade Harry to set that up? That would have affected history, since they helped at the Department of Mysteries and at the second war."
