What happened shortly after margo showed up at q's bedroom window?

After Margo shows up at Q's bedroom, she takes him on an adventure in the middle of the night around their town in Q's parents' minivan. They spread raw and smelly fish inside her supposed friends' houses, and wax the eyebrows of the school bully. They sneak into the Sea World and the Sun Trust buildings, and stay up talking through the night. When all her eleven "missions" are completed, they head back home. Shortly after, in the morning, Q discovers that Margo has disappeared, as she had frequently done so before.
