The Important Person - S1.E11

Helga and Chit are caught up in a storm and rescued by a ship which turns out to belong to the GED Organisation - Gherta is on board attempting to trace Kirchner, who appears to still be "alive". Meanwhile, the Children track Helga to Kokkuri Island at about the same time as Thoma goes searching for her, and they decide to stick together in order to find her - however, they are unaware that Kirchner is coming closer to the research ship, and Shiberu is also on board.
