Caretaker Argus Filch: For God's sake, pull yourself together man. You're going into the Forest after all. Got to have your wits about ya...
Draco Malfoy: The Forest? I thought that was a joke. We can't go in there. Students aren't allowed. And there are... werewolves.
Caretaker Argus Filch: Oh, there's more than werewolves in those trees, lad. You can be sure of that. Nighty-night.
Argus Filch delivers the students to Hagrid for detention in the Dark Forest.
