Before leaving, Star goes around Mewni to say goodbye to everyone. While happy at first, Tom begins to suspect that Star is stalling, especially when she starts saying goodbye to people he has never met like Doop-Doop, her very first spell which she left abandoned in a shed. Star breaks down and reveals that she does not know what to do with herself and does not know if she wants to travel. Tom decides to give Star some space until she figures out her life. Star returns to the Diaz family where she meets Marco's newborn younger sister Mariposa.

Sensei and Oskar are shown to have become employees at the restaurant, which Janna has been banned from, while Principal Skeeves and Mr. Crandle show no ill will towards Marco, who earned his high school diploma early. StarFan13 is still obsessed with Star and still romantically ships her with Marco, while Ferguson and Alfonzo have befriended a group of relatively attractive friends who are into D&D. Marco begins to dread Jackie Lynn's return as he felt that the relationship ended badly. She finally shows up and reveals her new girlfriend, Chloe. Jackie admits that she is still on good terms with him and that their time together was great before suggesting that Star is someone worth keeping, leaving Marco feeling good about himself.
