While helping out in Community Service Day, Will and Hay Lin find a strange Meridian graffiti which The Mage identifies as belonging to a Beast, living in Heatherfield in human form. Will suspects her History teacher, Professor Collins, and the girls immediately formulate a plot to force the suspected monster into revealing his true form.

Phobos is preparing the Ritual of Amalgamation. He needs symbols of Elyon's body, mind, and spirit. Cedric takes her hairbrush, A+ math test, and is trying to take her breath. Meanwhile, Martin catches a glimpse of a Hermeneuta beast from Meridian and the only thing that will get him away long enough for the girls to send it back home is a date with Irma. Catching the little beast is not as easy as it sounds, especially when the mom shows up. In the end, Cedric finally captures Elyon's breath in a balloon and all that's left is to take her to Meridian.
