Amelia hates slugs. So, as test of her mettle, Elsa has assigned her to help Gunther clean the critters out of the gearboxes. Being trained as a witch, however, makes Amelia determined to make sure the slimeballs don't come back.

After cleaning the slugs out and dumping them in the woods, Amelia and Gunther transplant some of the mint bushes to the area where the slugs have been getting into the dam. Amy explains that slugs hate mint, and it will keep them away.

The next task is to check the walls in the service tunnel, which involves moving aside old crates. Amy gets a familiar feeling, and finds something of Stephan's that was obviously left out for her to find.
