Steven tries to discover why people are disappearing from Beach City.
- Adult Fear: Given that people are going missing, fear is an appropriate response. Sour Cream is putting up "missing" signs of Onion and Barb becomes visibly scared when Steven mentions that Sadie was planning to return home after the party.
- Alien Abduction: Homeworld Gems kidnap Connie, Sadie, Lars, Jamie, and Onion, and are planning to head back to Homeworld once they find "My Dad".
- Armor-Piercing Question: When Connie brings up the idea of there being Gems like Steven (half-human, half-Gem), Garnet retorts that it's unlikely. Connie asks her if she's sure, which leaves Garnet speechless.
- Badass in Distress: Although Connie has been training well and taken down large Gem monsters before, when she tries to defend herself against the two Topazes, she gets stuck in their Fusion very quickly, probably because she didn't expect them to be able to do that.
- Bitch in Sheep's Clothing: Aquamarine uses her childlike appearance to seem innocent and helpless to the humans. When she finds the ones she wants, however, she lets the mask slip and calls for the Topaz soldiers to absorb the humans.
- Caged Inside a Monster: Topaz holds the humans she and Aquamarine are looking for in her body.
- Call-Back: The Crystal Gems point out that Navy stole back the Roaming Eye in "Room for Ruby", so if the Homeworld Gems take the humans off planet, there will be no way to reach them as a team.
- Continuity Nod:
- Steven sings "Hey, Mr. Postman" again while waiting for a package.
- Steven asks Sour Cream if he'd checked for Onion in the place where he met his friends in "Onion Gang" or Onion's hidden room from "Onion Friend" (which Sour Cream calls Onion's "office").
- Barb is initially not worried about Sadie's disappearance because she figures Sadie and Lars are on another "Island Adventure".
- Compound Title: With the following episode, "I Am My Mom".
- Cross-Referenced Titles: With the following episode, "I Am My Mom".
- Deliberately Cute Child: Aquamarine isn't actually a child, but takes advantage of looking like one. Due to being small and having Puppy-Dog Eyes, she can pass among people innocently. This allows her to find the humans' names without much suspicion.
- Face on a Milk Carton: Sour Cream passes out "missing" fliers for Onion, who disappeared after the events of "Doug Out". They're repurposed "WANTED" posters.
- Facial Composite Failure: Steven gives a description of Aquamarine that Garnet, Amethyst, Pearl, and Connie each use to make a sketch. Connie makes a very anime-style drawing that's so outside of the show's (and especially Aquamarine's) artstyle that the clothes and teardrop gem are the only clear resemblance. Amethyst drew what looks like a dog (with wings and a teardrop gem). Pearl drew an adult-sized crying angel wearing ballerina shoes. Garnet drew a self-portrait.Connie: I think I made one eye bigger than the other.
Amethyst: I was going for a feeling.
Pearl: Honestly, I can't even draw a circle.
Steven: OK, Garnet, you just drew yourself.
Garnet: Uh, I like me.
- Failed a Spot Check: Aquamarine and Topaz fail to realize the significance of a human summoning a pink shield out of thin air. Connie's sword can be explained, but not the shield.
- Fusion Dance: Weaponized by Topaz, who is actually two-in-one who Fuse over their intended targets to seal them within her body.
- Hair Decorations: Aquamarine's bow lends to her looking like an innocent lost child, though her actual demeanor is far less cute. When she whips the ribbon off her head, it turns into a wand that projects a Tractor Beam.
- Impairment Shot: Steven, after getting Blown Across the Room by Aquamarine, tries desperately to stay conscious before finally passing out.
- Knight of Cerebus: Aquamarine and Topaz take things in a different direction once they appear.
- Noodle Incident: "I know from experience that the Big Donut does not accept magic beans as currency."
- No-Sell: Rose's sword doesn't poof the Topazes while they're Fusing.
- Oh, Crap!: Connie when she realizes that her sword does nothing to defend her from the Topazes.
- Orphaned Punchline: Amethyst drinks a can of beans because "they're good for the heart", part of the playground saying where the other half is "the more you eat, the more you fart".
- Questioning Title?: This episode is one of the few to feature punctuation, with a question mark at the end of "dad".
- Shout-Out: A Creepy Child with a British accent repeatedly asks "Are you my dad?" while ignoring all other inquiries from others? Sounds similar to "Are you my mummy?"
- Silent Partner: The Topazes (and their fusion) say nothing at all, while Aquamarine does all the talking.
- Title Drop: Aquamarine asks Steven "Are you my dad?", then leaves when he says no.
- Tractor Beam: Aquamarine has a wand which can fire an immobilizing beam, similar to Syndrome's zero-point energy gauntlets in The Incredibles and the one that Peridot used on Pearl in "Catch and Release".
