The locker room

Harry decides to look for her in the locker room. He hopes he's not caught trying to sneak in. Not only would he be in danger of losing his job, but Ginny would kill him for embarrassing her.

He decides it's worth the risk. He sees the last of the Harpies heading in the direction of the locker room, and he follows her. He pulls out his Invisibility Cloak and puts it on. That should prevent anyone from seeing him.

As he nears the locker room, he hears the sound of giggling coming from an open door. He peeks his head in and what he sees surprises him.
