Episode Title:Crystal Clear / The Hard Way.Episode Description:Crystal Clear: Rhombulus captures Star and Marco and encases them in crystal, believing that the former is the cause of the glitches that are affecting the dimensions.

Star agrees not to tell the high council about the situation provided that Rhombulus not tell them about Star's losing the Book of Spells and Glossaryck.

Ludo learns and masters a levitation spell and is quite proud of his accomplishment. But when he learns there is a secret chapter that Glossaryck withheld from him but showed Star, he makes Glossaryck unlock them. Ludo reads the forbidden chapter and gains some dark magic, but when he talks with Glossaryck, he now has the voice of Toffee, who has possessed him.
