Willow rushes into the gym locker room late. Buffy worries over Willow's attitude and how much time she's spending with Malcolm. Willow has blown off a few classes.

Buffy chats with Dave about how to find Malcolm's location. She thinks Dave could be Malcolm; however, he's acting too strange about the situation.

The computer screen sends Fritz a message to kill Buffy.

Willow is chatting with Malcolm online. He starts to give her the creeps after spilling information about Buffy's permanent record.
