Lily Luna Potter fascinates me.
This is only a recent discovery, by the way, but if Teddy is her Godfather, and Luna is her Godmother, and somehow she's the only Potter in Slytherin, I reccon she could be an utterly wacky character. I actually have some WIP chapters about her, but alas, I shant give you the goods till I have proofread it at least four times.
Four is a magic number and I can't even remember why I like it so.
Oh Wait, Transformers.
Jazz has a Four.
I am Number Four is also a great movie.
