The Phantom inquires Christine with a rather strange question, conveniently when Raoul is nowhere to be found...

"Christine, angel?" Erik asked. Christine smiled. "Yes, Erik, what is it?" He stared at her. "Can a person breathe inside a washing machine while it's on?" 

Christine thought for a moment at what a peculiar question that was. "Well, no, I don't think so." She answered. Suddenly, it hit her. Her eyes went wide. 

"Erik, where's Raoul?" 

Erik was already walking away. "I just wanted to make sure." 

Muffled screams were heard from the laundry room soon after.
