Not the cute kind of cuckoo, or the lights-on-but-nobody's-home loony. She's really, genuinely, sold my-soul-to-the-devil crazy. She don't care about me or anyone else in the place. I mean, sure, she killed Frankie. And maybe she wanted to save the rest of us or whatever. But mostly, she just plain wanted to kill him. I mean, she stabbed him like a zillion times. Then licked his blood. I don't remember Wonder woman ever doing that at the end of an episode.
