Thoma brings Chito and Helga to his secret island, Kokkuri, where he's made provision for hiding out. When Chito runs off into the forests to get fruits for her, Helga is completely absorbed in her painting and fails to notice. Thoma ends up running into the forest after him with Helga following behind despite Thoma's repeated insistence that she'll just get in the way. Meanwhile, on the mainland, Cooks continues to investigate the Children. The old man from the end of the last episode is brought to the police station but dies soon after, and is identified as a man named Glass who went missing several years ago. Video footage of him in custody shows his dead mother sitting beside him until she suddenly vanishes.

トーマはヘルガとチットをパパン島のそばにある、コックリ島という密林に覆われた小さな島へ連れて行く。そこは施設の人間にもきっと見つけられない、トーマの秘密の島なのだ。家から食料を持ち出したりして二人の世話をするトーマだが、相変わらず心を開かないヘルガにだんだん苛立っていくのだった。同じ頃、パパン島から遠く離れた東本土のとある住宅地のある家を一人の老人が訪れた。老人は３年前にテスト飛行で亡くなったはずのパイロット、グラスの名を名乗ったが、警察に保護されてすぐ死んでしまう。
