Will and the rest of the girls try to tell Elyon the truth about Phobos and Meridian, but that becomes very hard when Phobos teaches his sister to make ghostly images of herself to confuse her former friends and the rebels. The real Elyon is upset that she didn't bring her sketchbook from Earth, so Phobos sends Lurdens through a portal to her old bedroom to fetch it. The creatures also trash a stash of chocolate, and Blunk is able to use the scent to track them to Phobos's and Elyon's secret Meridian mountain hideout. The Guardians and Caleb search for Elyon under the mountain but are ambushed by Lurdens. Forced into the open, they battle Cedric on the mountainside before returning to Earth, no closer to warning Elyon of the terrible danger. In the B-story, Will needs some privacy. In order to save Elyon, the girls trick their parents into thinking they are having a sleepover party, but Will is grounded for having a mess in her room.
