first off: you forgot David Tennant!
anyway. I've only seen Doctor Who, but I love your background :) I want to watch Sherlock, but it's TV-PG-14, and my parents won't let me :( Supernatural... I dunno, I'll have to look it up.
so, the main reason I'm commenting is because of your username. Here's a guess: you're trying to become a mermaid with spells. Completely wrong and now you think I'm some kind of insane person that you should stay away from, close, or correct? Just wondering ;)
