Maddie: Can you ask Mr. South if he knows where this door leads to? How did I not know we had a fallout shelter?
Simon: Mr. South said it's been here since the Cold War. That it hasn't been used in decades.
Maddie: Wait. We can talk down there. Doesn't that mean that somebody died?
Simon: Yeah. But who?
Maddie: Where do you think that goes?
Simon: No idea. But I'm guessing this is how Claire dragged your body out of here.
