Freaking FINALLY. She has a name!! Everyone, meet Lamia, and yes, she totally conjured that giant horse with her magical girl powers. So see? I'm not crazy, I didn't just randomly introduce a big WTF moment like that for shock value. Not totally, anyway. It had a purpose!
Her name, by the way, comes from several different sources. Yes, part of it comes from the Greek mythology, but it is also an Arabic name that means "shining, radiant". I think that version is pronounced "LAH-mia", which is how I pronounce her name (not LAY-mia, like the Greek variant). I think I first found her name in a Latin dictionary under the term for "witch, sorceress", though I am not sure how you pronounce it in Latin.
