I really don't know why this happened...
Snape. Cheering charms. Need I say more?
Boredom is a terrible thing. Rated T, because no child should be subjected to singing, dancing snape.
Just another silly little story, the title sums it up. Minor edit added the missing line breaks
Basically, what happens when multiple characters travel back in time in order to save the potters. (Or, rather, when a bored wannabe author writes about it at one A.M.) Rated T to be on the safe side.
