In the meeting room, Paulina is educated about the crew's home planet Astra. They soon discuss the histories of their respective eras. In the crew's school, they learn not to focus on the past but the future. Paulina is also left perplexed by the false historical information about World War III and the Cuban Missile Crisis. She's then disclosed the events that took place in World War III. In turn, Pauline discloses information on how a giant asteroid could kill all life on the planet when it struck. As a way to preserve a fraction of the history and life on Earth, a planetary expedition was created to seek out new planets to inhabit. The thought of interplanetary immigration is thought to be impossible, however, due to artificial wormholes, it makes it possible. This makes all of the inhabitants of Astra are former Earthlings. It's also surmised that the icy planet they once discovered was really Earth. The topic is segued by Aries who wants to focus on the bad atmosphere. Afterward, Aries and Kanata have a talk.

Lead into a narrow cave, the wormhole disappears once he regroups with Aries. The following day Kanata reveals his encounter with the artificial wormhole to Zack and Charce. He also reveals that Ulgar is a double agent out to kill them. So with Charce as bait, they try and entrap Ulgar in a cave but fail. However, it's revealed that Charce is the real double agent.
