Phobos uses the knowledge of Caleb's father's being alive to lure him and the Guardians to the Underwater Mines for an ambush. Fortunately, Hay Lin hears the guards whisperings, which allows the group's unimpeded access to the mines. However, the element of surprise is soon lost and the group is on the move. Cedric floods the mine and sends the group plus Caleb's dad on an Indiana Jones-type mine cart ride to the main shaft. Once there, they use the guardroom to float to the surface and come face-to-lizard face with Cedric and a platoon of guards. Cedric tries to go after Caleb and the miners stranded in the remains of the guardroom, but Irma and Hay Lin cool Cedric out with a flash-frozen bubble. Phobos is sitting pretty in his castle, thinking that he has taken care of the major thorns in his side until the girls show up with the last laugh in his looking-glass floor.
