A frantic group flags down the rover and tells Jeremiah and Kurdy that men in orange suits just kidnapped a girl from their party. As Jeremiah and Kurdy chase down the abductors, a helicopter suddenly appears. The fleeing men dressed in orange protective suits drop the girl and climb to the chopper. One of them is left behind and Jeremiah and Kurdy witness an impossibility, as this man seems to be about 50 years old. Jeremiah and Kurdy take the man to Thunder Mountain where he is placed in a sealed-off room.

The leaders at Thunder Mountain are amazed when they realize that Markus and this man named Quantrell are familiar with each other. Both know that Markus's father was a doctor and Quantrell a base commander during the Big Death. They both also know that Quantrell locked down the Thunder Mountain base, leaving Markus's mother and father outside the mountain to die. For Jeremiah, the realization that Quantrell is from Valhalla Sector and may possibly know his father is Earth-shattering.

Quantrell reveals a homing device is planted inside him and Valhalla Sector will be coming for him. As the Valhalla Sector helicopters approach, Markus wants to release Quantrell to save the base but Jeremiah argues, hoping Quantrell can lead him to his father. The issue is decided for them as Lee Chin smuggles a man named Ezekiel into Thunder Mountain where Ezekiel turns off the air supply for Quantrell's clean room. With Quantrell dead, the choppers lose the homing signal and turn around. Having seen the kind of world Quantrell wanted to build, Markus makes a momentous decision. It is time for the people of Thunder Mountain to go into the world and offer help and hope.
