BUFFY: Giles, have you ever touched a ghost?

GILES: Uh, no. From what I've heard, uh, having a, a ghost pass through you is a singular experience. It's a, it's a rather, uh, cold amorphous feeling. It makes your hair stand on end.

BUFFY: You see, that's my problem. I touched the thing, but it didn't go through me. It bumped into me. And it wasn't cold.

XANDER: So, we're talking about what, an invisible person?

BUFFY: A girl. She laughed.

GILES: A girl on campus with the ability to become invisible.

XANDER: That is so cool!

WILLOW: Cool?

XANDER: Well, yeah, I would give anything to be able to turn invisible. Well, I wouldn't use my powers to beat people up, but I'd use my powers to protect the girls' locker room.

GILES: It must be a fairly heady experience... having that ability.

WILLOW: How'd she get it? Is she a witch? 'Cause we can fight a witch.

XANDER: Hmm. Greek myths speak of cloaks of invisibility, but they're usually for the gods. (gets looks from everyone) Research Boy comes through with the knowledge!

BUFFY: This girl's sorta petty for a god.

WILLOW: She's got a grudge. But why Harmony?

XANDER: Harmony and Mitch. The common denominator is...

BUFFY: Cordelia!
