After Madame Natasha leaves the dam, Amelia asks Olivia for help distracting Zahn away from doing repair work. The distraction of choice is returning the fixed pieces of equipment to Dr. Pike: the speaker horn for the voice recording device and the transmission for the spark wheel.

After the usual 'meeting Igor for the first time' bizarreness, they meet with Dr. Pike and play the cylinder, hearing her great-uncle Orifice describe how he captured a troll and his discoveries – and also that he sounds like he's becoming paranoid and delusional.

It's agreed that Pike will do more research before any of them try to explore down the underground canal.
