Episode Title:
Demoncism / Sophomore Slump.
Episode Description:
Demoncism: A jittery Pony Head confides to Star that Tom is undergoing a "demoncism", which is meant to turn him into a more normal, tamed being. They secretly infiltrate the ceremony for Star to rescue Tom, but the demoncism goes ahead as scheduled, only for its organizer to reveal that he still has plenty of rage in him. They are then seen holding hands, much to Pony Head's dismay.
Sophomore Slump: On Earth, Marco begins to spout so much of his adventures in Mewni that his friends, peers, and teachers begin to distance themselves from him except for Janna. Jackie suspects that he isn't letting go of these so easily, so Marco takes her out on a date to prove he's moved on and a better boyfriend to her. Upon discovering he is secretly hiding the cape King River gave to him on Mewni under his hoodie, she tells him that he's only staying in Echo Creek to make her happy for her sake. She kindly breaks up with him and leaves. Deciding he wants to return to Mewni as an exchange student, his family and friends see him off.
