On Earth, Marco begins to spout so much of his adventures on Mewni that his friends, parents, and teachers begin to distance themselves from him. Jackie suspects that he is not letting go of this so easily, so Marco takes her out on a date to prove he has 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 is only staying in Echo Creek to make her happy for her sake. She kindly breaks up with him and leaves. Afterwards, Marco decides he wants to return to Mewni as an exchange student.
