After handing off Gunther to a lapi guard, Amy runs for the dam, following the trail of zapped zombies left by Natasha. She catches up the woman, and the two of them disable another group of zombies.

At the dam, Amy breaks off from Natasha and goes to the dining hall to find Elsa, telling her that she has to get Stephen's music box to Zahnrad, and to show her where he's being kept. Elsa leads Amy through an underground network of tunnels to where Zahn is recovering.

Zahn doesn't really understand what's going on, but Amy and his mother drag him off to his workshop, since Valicross knows about the other room now from Gunther. There she spots figures on the dam, and rushes back off again to help out.
