Let's just say we both lead really elaborate lives these days.
But as for Cordy, our friend in LA passed his visions along to her before he died, and now she gets them. He was half-demon; she's not. There's a lot more that comes after that, but it hasn't happened to her here so it's not relevant. And hopefully it never will be.
She's gonna be okay, though, Buffy. Don't worry. We'll get her fixed up.
