Ep 25. For The Future

Back at Star Hole, Adam has a dream in which he sees his parents in some sort of control room. He sees his mother coughing, then they place him in the cold-sleep capsule, and he awakes with a start. Later, the children discuss the dream. Chako and Shingo believe the ruins are a spaceship, and want to return with Adam to spend several days investigating. Kaoru takes them there, while the rest of the children move back to Everyone's House. Five days pass while Chako and Shingo investigate every nook and cranny in the ruins, and Adam tries to recall the memory of his parents. Adam eventually remembers his mother's last words - "for the sake of the future", and when he speaks them out loud, the walls light up, and the centre of the room's floor lowers down, revealing a hidden door to the control room.
