What about Amy teleporting Kennedy? No other real witch in the room. I am not sure where she would draw that kind of power. Unless she got some kind of a high from rack or the same way Willow drew power from Kennedy and Anya, or could have been elesewhere. Either way we know Willow is the more powerful of the two. I just had to throw that in of course.
The thing with Kennedy happened much later than the episode(s) in question. She'd had plenty of time to come into her own power (or "borrow" it from the rest of the Wicca Group if she's still evil, which it appears she is) by then.
