Marco attempts to consume 50 tacos in order to win a special prize that is offered at Britta's Tacos.
- Ambiguous Situation: Marco confronts Mr. Candle about whether he's the same person as Sir Crandle, and Candle slips into using the words "Lifelong Post" after denying he is. Either there is someone identical to him, or maybe he has something like Dissociate Identity Disorder, or maybe he's simply moonlighting jobs between dimensions.
- Audience Surrogate: StarFan13 continues this role, even being the only non-main character to see the whole plot from beginning to end.
- Beyond the Impossible: Marco could not get over the fact that Jackie and Chloe could handle consuming tacos with Echo Creek's "White Hot Pain Peppers", which are so spicy that they were banned in sixteen states.
- Bi the Way: Jackie states that her trip to France and meeting Chloe taught her a lot about herself, and she and Chloe hold hands as they skateboard away from Britta's Tacos. One of the storyboard artists later confirmed that Jackie and Chloe are in fact dating.
- Bottle Episode: A majority of the episode is simply a reunion that takes place around the titular Britta's Tacos.
- Brick Joke: Star guesses that the prize for eating two hundred tacos is a T-shirt, which Marco thinks is too mundane a prize. At the end, it turns out it was a shirt, although it was stolen long ago.
- Burger Fool: Sensei Brantley and Oskar are now working at the taco stand.
- The Bus Came Back: Since Marco returned to Earth, we finally meet again multiple Earth character who weren't seen since Sophomore Slump.
- Captain Obvious: Star asks what Oskar's done since she last saw him and he proudly informs he got a job at Britta's Tacos—while standing behind the counter in uniform.
- Cassandra Truth: Brantley actively refuses to believe Mariposa isn't Marco's daughter, and assumes her being his sister is just a cover story.
- Continuity Cavalcade: Pretty much every human character from the show comes to Britta's to talk to Marco and Star.
- Closet Key: While Marco was in Mewni, Jackie spent a year in France and met a girl named Chloé. It's heavily implied this made Jackie realize she was attracted to girls and they're dating.
- Entertainingly Wrong: Sensei and Ferguson both imply that Marco went to live with Star on Mewni because he'd gotten her pregnant. The timing of their absence works out for this (Star's been gone for a year, Marco visited her for a month or so and came back to Earth, then went back to live with her 9 months ago after suddenly breaking up with Jackie) and baby Mariposa's family resemblance to Marco is obvious, but this couldn't be further from what actually happened.
- Extreme Doormat: Because Star chooses to be a Lazy Bum the whole day, she just lets Starfan do whatever she wants with her, including manipulating Star's hands to cast magic.
- Freudian Slip: Mr. Candle's insistence that he's not Sir Crandle is further undermined when he accidentally says his job is help children choose their "post".
- Grade Skipper: Played with; Marco got his GED at fifteen because he'd been out of school in Mewni, but he is Older Than They Look at this point.
- Hollywood Nerd: To Marco's confusion, the people in Alfonzo and Ferguson's D&D group are all stylishly-dressed and conventionally attractive.Alfonzo: Oh, being a nerd has gotten super cool since you left!
- Internal Reveal: Jackie by now has figured out that there is something going on between Marco and Star.
- Is That Cute Kid Yours?: Practically everybody seems to think that little Mariposa is Marco and Star's daughter. It doesn't help that almost no one had seen Star for a year.Cloudy: Special delivery from Star!
Cloudy brings Mariposa to Marco
Ferguson: Cool, Star and Marco had a baby!
- It's the Journey That Counts: Marco realizes hanging around looking for loyalty punches was worth it just to catch up with everyone in Echo Creek.
- Jerkass Realization: Marco realizes he shouldn't have spent his time as Jackie's boyfriend unknowingly pining after Star. Jackie, for her part, doesn't hold it against him.
- Lazy Bum: After Marco tells Star "summers are all about relaxing and doing nothing", she doesn't even bother walking, getting Cloudy to carry her everywhere.
- Masochist's Meal: By the end of the day, Marco has bought so many tacos the stand has actually run out of ingredients - except for some Echo Creek "White-Hot Pain Peppers."Marco: Haven't those been outlawed in, like, sixteen states?
Sensei Brantley: What am I, a cop? EMBRACE THE PAIN!
- Non-Giving-Up School Guy: Parodied; Star assumes Principal Skeeves and Mr. Candle will be after her for "missing class" for a year, even though she's no longer a student and it's summer.
- Persona Non Grata: Apparently, Janna is banned from Britta's Tacos for life. No one knows why, but she tried to use a Paper-Thin Disguise numerous times to get in.
- Running Gag: People thinking that Mariposa is Marco's daughter and not his sister.
- "Shaggy Dog" Story: After having his two hundred tacos card punched, Marco and Star find out that the prize was just a T-shirt, which had been stolen some time ago. Marco, however, finds the journey more rewarding.
- Shipper on Deck: Jackie for Star and Marco.Jackie: Now she's a special girl, Marco. Make sure you don't mess that one up.
