Hero girls, boys, and villains are all caught up in a class where they have to take care of an egg over the weekend.
Tropes:
- All for Nothing: In the end, not only does no one manage to save their egg, but the teacher dismisses the whole assignment, which was given out by a substitute. To make matters worse, at the end of the episode they now have to take care of living hamsters.
- Bait-and-Switch: When Kara's about to swipe an egg to save herself from summer school, her morals prevent her. At first.Kara: "I can't do it! I can't steal! There has to be another way. Like...(switches places with Harleen) ...you stealing."
- The Cameo: Jimmy Olsen briefly gets caught in the middle of the others' egg chase.
- Did Not Think This Through: Due to being too caught up in playing the mother, Zee compromises by giving Oliver half of the egg, which she boiled and then split into two. She realizes her error soon after talking to Oliver.
- Does This Remind You of Anything?: Zee and Oliver pretty much act like a couple whose relationship is on the rocks while taking care of their egg.
- Egg Sitting: The entire class is split into pairs and assigned an egg to take care of for the weekend. None of the eggs make it to Monday.
- Establishing Character Moment: The beginning classroom scene manages to do this with all the seventeen students present and also Mr. Chapin, repeating each of their personalities and/or quirks as shown in previous episodes.
- Failed a Spot Check: When they're at the LEXpress store getting packing material to make sure their egg doesn't break, Harley and Kara fail to see it fall into a package and get shipped out.
- Failure Montage: Right after the assignment is given, several pairs of students immediately fail it:
- Diana and Karen fail to notice their egg rolling off Diana's desk.
- Leslie pulls a sleight of hand that causes her egg to be crushed when Tatsu goes in for a handshake, on purpose.
- Jessica looks forward to the assignment, so Pamela eats her own egg out of spite.
- Barry assumes that Carter, being a bird-man, can literally sit on the egg to keep it safe, and puts it on his seat. The egg gets smashed when Carter shifts slightly.
- Fire-Forged Friends: Parodied for laughs. Kara and Harleen start off in Teeth-Clenched Teamwork, quickly become partners in crime, and later hug and sob like a pair of BFF's would (ironically over the fact that their impending F means they'll be spending all summer together in make-up classes).
- For the Evulz: Leslie tricks Tatsu into crushing their egg in a handshake, even though it means they both get an F.
- Freeze-Frame Bonus: When the last egg appears, close-ups of all twelve characters present are quickly put up onscreen, and then eye-shifts have each of them looking towards their assigned partner, and note that Barry and Carter are the only partners whose close-ups are not next to each other but they still look in their directions.
- Here We Go Again!: After the whole egg fiasco, the class is asked to take care of the school hamster's babies.
- Innocently Insensitive: Not that he's being nice by any means, but when the teacher assigns partners he points out Carol's is missing in action, and in the process indirectly offends her by pointing out she's single.
- Irony: Mr. Chapin says that while he knows the class doesn't understand things like responsibility or protecting the helpless, he knows they care about grades, yet most of the students are superheroes and some of the students actually don't care about their grades. Tellingly, those same students happen to be villains — Doris/Giganta who skipped class; Leslie/Livewire who intentionally tricked Tatsu/Katana into crushing their egg; Pam/Poison Ivy who eats her and Jessica's/Green Lantern's egg so she wouldn't have to hang out with her.
- Like an Old Married Couple: Some of the pairings start acting like this way, most prominently Hal and Carol, and especially Zee and Oliver.
- MacGuffin Melee: In the end, only one egg remains, and the entire class fights over it. The fight ends when Pam gets ahold of the egg, and puts it in her sandwich.
- Oh, Crap!: Quite a few when the eggs get destroyed one by one. The most epic one probably goes to Harley and Kara, who were planning to steal Zee and Oliver's egg, when it turns out Zee hardboiled it and cut it in half (Kara even Faints in Shock). Zee has a more subdued one of her own a second later when she realizes what she did.
- Rage Breaking Point: Selina reaches hers when, after enduring hours of Hal's sexism, he casually insults her intelligence. She smashes their egg on him and leaves.
- Slice of Life: No crimefighting or costumes at all (except Batgirl out joyriding), just comedic school hijinks. And no superpowers or special skills get used (except for Selina Kyle's climbing skill, and Kara's strength using the mallet).
- Teeth-Clenched Teamwork: The chase on the bumper-cars shows Zee and Oliver working back together, Selina paired back with Hal, and Tatsu and Carol now working together.
- Tempting Fate: Happens to nearly all of them, but Tatsu gets it the worst.
- Wild Card: From the start Pam Isley isn't at all interested in participating, only in eating the eggs, appalling everyone else.
