S1E4 · Zugzwang

Claus and Lavi are back at their home, with Alvis sleeping on their bed. Claus has decided to take the mission, much to Lavi's annoyance. Alvis awakes and asks for her nanny, Gita but the woman died during their escape. Claus isn't sure how to handle it, but Lavi tells Al that Gita had to go away for a while. After eating, they settle in for the night, but the star-shaped ship finds Al in the house. Claus and Lavi have to escape, and their house is destroyed in the process. Although they don't use their engines in the waterway, the star-shaped ship still finds them. They narrowly escape, appearing to damage the star-shaped ship enough to do so. At the temple ruins, where they were to bring Al, they are attacked again and the star-shaped ship snatches Al. Claus tries to fight it with a rock and is knocked out. Just as he is about to be killed, a shot rings out. Alex has shot the pilot of the machine and saved all the children.
