When Neville was 6, his grandmother decided he should have a friend over. In the tradition of clueless parents all around the world, she invited Neville's worst enemy, Seamus, another 6 year old with a temper. Last time Seamus had seen Neville, they had got in a fight over cake.

Needless to say, they were no longer friends. But Seamus still came over, and, just like the muggle children of the same age, they decided if they were stuck for an hour, they would play.

Seamus decided he wanted to play dark/light, and he would be the bad guy. He gave Neville a charm, and said "this means you are a good wizard of the same level as me, but not bad. Neville took the charm and they started to play.

"I am an evil Dark Lord!" Seamus cried. "YOU WILL NEVER DEFEAT ME!"

But Neville jumped him. "Oi!" Seamus yelled, "Not fair!" But Neville sat on him for a while and Seamus gave up.

And that is how the dark lord was defeated, although really, the case of Harry Potter was remarkably similar. But this happened first, and as the saying goes, 'first come, first served.'
