Jared grows paranoid of the evil force conspiring to get Spiderwick's Field Guide; taking Lucinda's warning to heart, Jared wants to find the pages with Simon alone, but Emiko, Hatcher and Calliope can't help joining the adventure.

A divide between the twins widens as they split up with Emiko and Hatcher to find more pages; Calliope tries to connect with Simon; Bree tries a different approach to fencing, forcing Mallory to get out of her head and throw a party.
