Buffy: (picking up a pencil and a computer disk) Oh, hey. You dropped this.
Willow: (putting the disk into the computer) It's not mine. It might be something of Ms. Calendar's.
Buffy: This feels kinda morbid.
Willow: I've gone through most of her files already.
Buffy: Does that make this less morbid or you really morbid?
Willow: I had to. To teach her class.
