[She falls into the explanation easily and almost cheerily, as if this were commonplace for her.]

There was this book he'd been sealed into by some monks a few hundred years ago, and Giles was scanning in all his books, you know, updating to the technological age. When the book got scanned in, the demon got uploaded. Except he could only take physical form by inhabiting a robot body or something? I don't remember, it was a few years ago.

Anyway, he'd been talking to me online and tricked me into thinking he as a sensitive misunderstood human boy, and then he came back to the realm of the living and offered to let me rule at his side. I politely turned him down, by which I mean I freaked, and he tried to kill me. So I hit him with a fire extinguisher and Buffy shoved him into a breaker and electrocuted him.

That was the end of Moloch.
