What changes the most about Buffy, each time you return to the show?

It's amazing how the styles of clothing have changed. We were joking recently, because the first year when we were on I wore plaid pants and sweat shirts - and now I'm in these sexy Britney Spears get-ups.

Also, we all had very big, layered hair, Jennifer Anniston cuts, and so that's all changed. But it's a lot of different things, just... some of the characters have grown, [particularly] Willow.

Would being made up as a demon or vampire disturb you?

Not at all, I think it would be fun. There is so much when you dress up as a character. It really helps you feel who you are, and I think that would be such a great opportunity to feel that, to get into that character.

[It's] such freedom with the mask, to go in there and just be. I would love it, it would be fun.
