Plot

At Echo Creek Academy, Celestia, Luigio, Paulie, Alex, and Murielle, are leaving an assembly at the auditorium and heading to lunch, when Paulie mentions that Hoover is absent, exciting Celestia and Luigio.

With that, Celestia and Luigio leave lunch to go see they're subsitute, who is a short and stocky woman named Miss. Maude. With that, Celestia and Luigio sit next to each other as Maude begins to tap dance around the classroom, exciting the class.

On Mewni, Marco is heading to greet the head of the Junior Castle Guard, who is none other than Lord Skyle Lovebird, who acts cocky and arrogant, even mentioning how Star should've chose him instead of "Skrawny old Marco", much to Marco's annoyance. Marco asks if Skyle is going to keep talking or let him help the JCG with they're work. Skyle gets cocky again, mockingly questioning if he really needs Marco's help. Annoyed, Marco brushes past Skyle, who follows him and still tries to annoy Marco as much as he can.

Meanwhile, Glossaryck is watching Star, who is silently staring at the wall of Wanted Posters. Glossaryck mentions how Star has been staring at the Clock God's wanted poster ever since she got it, which was yesterday. Star explains that she went through a lot to bring peace between Mewmans and Monsters, and she feels like she is failing at it. Glossaryck tells Star that she needs to remember her title of " Star The Underestimated ", and star thinks that she is just underestimating herself. Glossaryck explains that a Queen always has a moment of doubt, but something or someone is always there to help them out. As he says this, the other Wanted Posters are shown, revealing other bad guys still at large, including the Baby Eater, Seth of Septarsis, Wyscan The Granter, Rasticore, the Pixie Queen, the Tooth Fairy, and the Clock God. Star decides to agree with Glossaryck and thanks him, and then asks if he knows anything about the Clock God and if the Mhc are lying about anything. Glossaryck states that if the Mhc are lying, then Star would've figured it out by now, and also explains that he does know this; the Clock God is still at large and he is much worse than Seth, especially with his memory gone. Star is shocked to hear this and tries to ask Glossaryck about it, but instead he tells Star to figure it out, and then leaves.

Back at school, Celestia is telling Luigio about the time she almost got her braces stuck on a fence with a bunch of Pig-Goats and also adds how it took an hour for her to get loose. Luigio states that once him and his Mom, Janna, went fishing. He frowns, wishing his Dad could've been there seeing him fish, but he wasn't. Celestia asks what happened with Luigio's Dad, and Luigio states that his Dad left since he had more important things to do. This infuriates Celestia, who doesn't understand what could possibly be more important than family, and Luigio wouldn't know. Just then, Maude appears in the middle of Luigio and Celestia's desks, asking what is important. Celestia immediately changes the subject, and asks to go the bathroom.

Celestia is allowed to go, but as she heads to the bathroom, she sees a man putting up a sign. Upon closer inspection, Celestia sees that it is a poster for Mr. Worthington, the school janitor from yesterday, who is missing.

Later, Celestia shows the poster about Worthington to Luigio. Luigio reassures Celestia that people are looking for him, but celestia does not think so. Luigio questions if they're going to start an investigation, and it gives Celestia an idea.

Back on Mewni, Marco is working with the Junior Castle Guard, putting in new plants, feeding food to the rats, polishing some statues, including one of Crescenta The Eager, raising the flags, training the squires, and eating lunch. While sitting with some Guards, Skyle appears, scares the other guys away, and sits across from Marco, much to the latter's annoyance.

Skyle begins taunting Marco with a piece of corn on the cob and begins mocking Marco for being human. This causes Marco to threaten Skyle with his sword, causing a crowd to appear. Meanwhile, Star is on the mirror phone with Pony Head, when she notices Marco and Skyle. Star quickly hangs up, and heads down to stop the fight. Skyle is happy to see Star and he gives her a knee, as does everyone else. Star chuckles, stating that she has a good reward for Skyle's modesty.

In the throne room, Skyle is exiled from Butterfly Kingdom by Star, causing him to sob, as he races out of the throne room, crashing through a wall and not the door.

Meanwhile, on post Apocalyptic Mew-Earth, the Monster Boy, who is named Klaus and a teenager, arrives at a refuge camp. He spends his days and nights recording a journal about what happened ever since the day his "Protector" vanished. Klaus closes his book, and goes outside to meet an old man named Gheff. Gheff offers Klaus some old bread, but Klaus refuses the offer. Meanwhile, Celestia and Luigio arrive at Worthington's apartment. In a flashback, it is revealed that Celestia and Luigio were out at a hot dog stand seeing Worthington head inside his home.

Celestia and Luigio try to look for clues inside the apartment, since the door was left opened. Celestia and Luigio end up finding a note signed by Hoover. With that, Celestia realizes that Hoover must've been the one to kidnap Worthington, and the two kids head to her house.

In a flashback, Celestia and Luigio were walking from the mall, where they see Hoover planting roses in her front yard. In the present, Celestia and Luigio arrive at the Hoover Residence. Hoover answers the door, and greets the kids.

Celestia gets straight to the point, showing Hoover the note left at Worthington's apartment. Hoover looks at it, saying that she did write it, but states that she has nothing to do with that "sad old man" and demands for them to leave her house before she calls the authorities. Celestia asks why Hoover wasn't at school, and Hoover says that she had an errand to do. Celestia thinks she is lying, and Hoover questions why it is any of Celestia's business. Celestia states that she finds it weird how Hoover left a note at the apartment where a missing man lives. With that, Hoover confessess that she was stood up at a date last night, and that she went to go confide in Worthington, but since he was not home, she left. Celestia believes Hoover, who states that she won't be coming to school tomorrow, and tells the kids to tell Maude she said hi. As the kids head home, Celestia questions how Hoover could've known about Maude.

With that, it is revealed that Maude is really a disguise for Hoover to use, to spy on Celestia since she does not trust her. Hoover then visits her basement, revealing Worthington kept inside of a box. Hoover then grins evilly, while glancing over at a Sea Captain hat. On Mew-Earth, Klaus is reading a journal belonging to someone named "Zeus Firefly", talking about they're being different cycles and different realities created by the Dame Der Zeit. With that, Klaus learns that the reality he is in , is in fact a new reality split from the original one, where the Apocalypse hasn't happened yet. Klaus throws the book, which lands at the feet of someone none other than the Guest, who tells Klaus that it is true. Klaus snatches the book, questioning how he would know that. The Guest chuckles saying, "How can I not? I'm the one who wrote it.", shocking Klaus.

Meanwhile, Star is dancing with Marco in they're room. Glossaryck arrives at Omni's dimension. Celestia is staring out her window, when she takes out her Amulet Wand and looks at it sadly. The Guest shows Klaus to the portrait of the Dame Der Zeit. "You have a destiny to fulfill Klaus. In time, you shall know what to do.", with that, Zeus takes out a Time Machine and hands it to Klaus, who gets teleported away. As for Zeus, he looks back at the Dame Der Zeit and leaves the room. Worthington is fed cat food by Hoover, as it is revealed that Hoover has an Orange Hourglass bracelet.

At the Skywynne Institute, Meteora is a little older and is in a relationship with a mew-man named Skipper. With that, Meteora joins Skipper and his friends at the party they're having. As the party goes on, Meteora notices Zeus in the crowd, but a person passes by, Zeus is gone, meteora ignores it, and continues to have fun.

Back at the Dame Der Zeit Room, Zeus is surrounded by people dressed in all black, as he states that the time has come, and that the light shall be in they're favor. The crowd applauds as Zeus smiles.

Meanwhile, Star finds an old Mewni Times newspaper, with the head article that reads, " Skywynne Institute Student Found Dead In Bed!? ". With that, Star looks out the window with worry.

Back at the Skywynne Institute, Skipper and Meteora are in they're room, since Meteora states how tired she is. Skipper decides to sleep with Meteora, but tries more than just "sleeping". This causes Meteora's powers to go berserk, and a blast ends up hitting Skipper in the face, knocking him on the bed and killing him. Meteora is deeply devastated and suddenly feels pain in her stomach. With that, Meteora flees, as other students and teachers find Skipper's dead body, revealing him to be the "Skywynne Institute Student Found Dead In Bed".

As for Meteora, she runs into Zeus. With that, Zeus and Meteora teleport away.
