In the Battle of the Labyrinth, Percy dreams about Luke. Luke is standing by Kronos's sarcophagus and is talking about the downfall of Olympus. While he's there, the monster cheerleaders show up. He's irritated that they've interrupted him, but asks for a report. They start to give the report, but then the head cheerleader senses Percy's presence and lunges for him. He wakes up.
