An unexpected revelation from Susan leads Finn closer to answers about his past.
- Adult Fear: As far as Minerva can tell, Martin intentionally ran away from the island—something she vouched for him not wanting to do—and took their son with him.
- Ambiguous Situation: It's left to the audience's imagination if Martin, who's shown to be an emotionally manipulative Con Man, genuinely fell in love with Minerva or was always using her as a way out of trouble and then later a Meal Ticket.
- On the one hand despite saying he wants Minerva to take him to dinner he ends up paying — with a huge gemstone of uncertain provenance.
- As You Know...: Kara/Susan explains Martin will be shuttled to "re-ed" after he's healed, and she jumps offscreen. Then she jumps back on-screen to explain that "re-ed" is short for "re-education".
- Bait-and-Switch Comment:
Minerva: I was completing checkout forms for Mr. Mertens, and it turns out he's medically unfit for re-ed. He's got a rare condition called garbage body.
- When an old woman offers a laser projector that shows a face as payment, Martin says "I don't like it. I love it!"
- Minerva makes up an excuse for Martin not to be re-educated.
Seeker: Uh, that sounds completely fake—coming from anybody but you, Dr. Campbell!
- Becoming the Mask: Martin may have started out trying to con Minerva, but seemingly really decided to become a dedicated father and husband. He didn't purposely abandon his wife or child, even going so far to save Baby Finn from the Guardian when he could have just jumped overboard and abandon Finn to be crushed. Unfortunately, after leaving, he seems to have relapsed.
- Broke Your Arm Punching Out Cthulhu: Martin becomes the first to get past the Colossus by breaking open its eye and shining a laser-light into, but this results in him and Finn being separate and lost at sea.
- Chekhov's Gun: The laser projector Martin got as payment earlier is later used to blind the Colossus.
- Comedic Underwear Exposure: As Martin tries to flee from the hospital, his medical gown shown off to Minerva his underwear that say "#1 at #2".
- Continuity Nod: The original human Founders are all but directly stated to be the tribe that Marceline helped escape from mainland Ooo a thousand years ago, with a statue of "Two Bread Tom" - their leader - in the park.
- Daddy Had a Good Reason for Abandoning You: Played with; Martin didn't intentionally abandon Finn, he took Finn with him while running from people out for blood, planned to escape by circling around the Island in a boat, and was separated after they ran into the Colossus, with Martin still trying to stay with Finn despite FIGHTING the Colossus, and only finally relenting when his only option became fleeing. Still, the situation was caused by Martin's own actions coming back to haunt him.
- Dumbass No More: Susan Strong wasn't exactly an idiot, but recovering her memories let her speak clearly instead of in broken English.Dang, I missed big words!
- Endangering News Broadcast: When Martin appears on TV when Minerva accepts an award, the old lady he double-cross recognizes him while in re-education and it allows her to find where he lives.
- Epic Fail: Martin's interrupted attempt at fleeing the hospital results in a window crushing his hand, causing him to fall over, re-damaging his legs and giving him a concussion. But these injuries let him stave off re-education longer—long enough to get Minerva to exempt him from it entirely—so maybe it wasn't completely accidental.
- Florence Nightingale Effect: When Finn's parents met, his mother was the doctor taking care of his father while his legs were broken, and Martin starts flirting almost immediately. This may or may not have just been Martin's ploy to use her as means to escape punishment.
- Foreshadowing: The song "Greatly Appreciated" played during Minerva and Martin's together montage. Whatever happiness they had would not last long.
- The Greatest Story Never Told: Martin, at least for a little while, was a good man, changed by Minerva's love, and palpably caring for Finn and Minerva. He wounded the Colossus, despite being completely unarmed and having to make sure baby Finn was safe throughout, only abandoning the life he had built with his family when he was utterly forced to. Neither Minerva nor Finn will ever know him as anything but a selfish, cowardly con-artist.
- In Love with the Mark: It's not clear if Martin really fell in love with Minerva or not, and, if he did, when it happened. They do have genuine chemistry, and he's not visibly up to anything bad while they're together.
- Insult Backfire:Minerva: So what are you? A con artist or something?
Martin: Yeah, you make it sound so glamorous.
- House Husband: Martin doesn't have a proper job during the time we see him living with Minerva and Finn, though he does get a certification as a barber just before he's forced to leave this life behind.
- Playing Both Sides: Martin takes payment from Hiders to guide them off the Island, then reports them to the Seekers to cover up that he can't really get them out. This backfires when one Hider forces him to come, he is arrested, and instead of passing it off as an misunderstanding, ends up getting assigned to re-education.
- Practical Currency: Martin only accepts payment in gadgets, though many are more novelties than useful. He apparently just finds the things nifty.
- Rewatch Bonus: Try watching Season 6's "The Visitor" again after finding out the truth about how Martin and Finn got separated.
- Shout-Out: A man with luscious hair who later goes bald becomes a barber and his current problems dealing with people may stem from a traumatic experience sounds awfully familiar.
- Stunned Silence: Finn is briefly at a loss for words when Susan tells him his mom is on the Founders Island.
- Time Passes Montage: A montage portrays Minerva and Martin dating, marrying, and having Finn.
- Trophy Room: Minerva's wall is full of awards and personal congratulations from all the people she's helped. It also has Martin's diploma from a barber academy.
- Wham Line:Finn: So wait, why are going to Founders Island?
Susan: I'm taking you back to your mom.
- Whole Episode Flashback: Most of the episode is a flashback to Finn's parents meeting, his birth, and Martin and Finn leaving the Island.
- Wounded Gazelle Gambit: When Minerva asks how Martin would con her, he points out she likes helping people so he'd pretend to look as pathetic as possible. In what may or may not be a coincidence, he does just that while being taken away for re-education, and she saves him.
