Something We Forgot

Go To
Don't you just hate when your friends make plans and leave you hanging?

"Hang on a minute, girls. You have a busy day ahead of you. You need to keep track of your time and your things."
Mrs. Mouseling, Angelina Ballerina: The Next Steps

So the adventure's over, the team beat the enemy or found the treasure and got out alive, and it's finally time to relax, say their goodbyes, and head home. And someone says, "I've got this nagging feeling that there's Something We Forgot."

Cut to a major MacGuffin that got left in the dungeon. Or an ally who got trapped and is still waiting for them to get back. Etc. An Oh, Crap! is likely to occur by the character having this realization. Another stock version of this is a parent or guardian—inattentive or overworked at best or neglectful at worst—having forgotten to pick their child up from school, a sports game, a club activity, or similar.

Related to Brick Joke and Locked Up and Left Behind. Often deployed as The Stinger. Contrast What Happened to the Mouse?, in which a dropped plot element does not get another mention, and Offscreen Inertia, when the audience is left to assume that whatever was forgotten will stay in that state permanently.

My Goddess Keiichi comes home and finds Peorth splayed out on his bed wearing lingerie with a bottle of wine in an attempt to seduce him, but he manages to slip away before she notices his presence.

They accidentally leave behind Najimi, who's panicking at being trapped in a room with a crazy stalker. In class the next day, Tadano muses that he feels like they forgot something.
  • Mysterious Joker:
    • At the very beginning of one chapter, Joker drugs a Hong Kong movie star named Jackie Lee so that he can impersonate the actor as part of a jewel heist. At the very end, there's a brief cutaway showing that Jackie is still tied up in the ambulance Kaitou left him in.
    • In another, it's revealed that Joker has been posing as Inspector Oniyama for the entire chapter. The rest of the cops are shown going home, apparently not realizing the real Inspector is still Bound and Gagged in a bathroom stall.
  • One Piece

Urouge lets out an 'Oh Crap' face before getting sent flying into three buildings.
    • A rather dark example happens at the end of the Impel Down arc. With so many freed prisoners on their stolen ship, and they're all too busy trying to fend off several Marine battleships, Luffy doesn't realize that a key member of the group is missing, until it was too late: Mr. 2 chose to stay behind on Impel Down to open the Gates of Justice. Jimbei was the only one aware of 2's plan, and 2 asked him to keep it secret from Luffy until they are past the Gates, or else they would never escape.
  • Pokémon: The Series
    • Team Rocket join in the effort in bringing power back to LaRousse City in Pokémon: Destiny Deoxys. Since they kept themselves hidden, the rest of the main cast didn't even know of the Rockets' assistance. At the end of the film, Team Rocket are still at it, not knowing that the crisis is over, let alone that the city's power is back on.
    • A karmic one (he was asking for it) in Pokémon: The Rise of Darkrai during the group's first trip up the Time-Space Tower. Ash (and Pikachu) challenges his friends to a race and he gets the lead because of a running start, only to realize too late that his friends used a balloon for their ascent instead. It's easy to tell who makes it to the top first, and after a few minutes of exposition Ash and Pikachu finally catches up with them, all out of breath from the climb.
    • When Pachirisu comes down with an illness Ash and Dawn send Gliscor out to fetch Brock who was in town. Of course, with Gliscor being unable to fly without the aid of wind pushing it in the right direction, Brock leaves Gliscor behind in order to get back on time and everyone forgets about it until the end of the episode where Ash freaks out.
    • There was an incident which scattered Ash, Brock and Dawn and their Pokémon throughout Canalave City. The teams eventually reunite at the end of the episode, and the humans ponder if they're forgetting someone. Brock dismisses the idea because he sees a pretty girl, and just as he tries to flirt with her did the missing party member, Brock's Croagunk, show up to halt his advances.
    • The same thing happens in an XY episode, where the gang has to "trade" Clemont to a spoiled princess in exchange for the PokéFlute, promising to go back for him. After thwarting Team Rocket and waking up Snorlax (the reason why they were looking for the flute), the festival begins, but then they immediately remember poor Clemont...just as he arrives, in his undies (he used his clothes to disguise a decoy to get away from the princess).
    • During a race in the Sun and Moon series, the normally athletic Kiawe falls behind the rest of the pack because part of the race involves pulling a wagon (with their Pokémon as passengers) uphill, and his partner is the very large turtle-dragon Turtonator. When the heroes celebrate the end of the race Ash scans the crowd of racers and finally caught on that Kiawe was missing: he never got past that leg of the race.
  • In the Tenchi Universe episode, "No Need for Runaways!", after the gang got back Kiyone's stolen spaceship and successfully escaped from the Galaxy Police, Tenchi realized that they forgot to pick up Ayeka and Sasami, who were left at the diner, washing dishes to pay for their dinner.
  • During the final battle of Bleach Fade To Black, Kon gets knocked into some spiritual goo which hardens over him. After the threat has passed and Ichigo and Rukia are set to head back to the living world. Ichigo feels they forgot something.

  • Right at the end of episode 3 of Saber Marionette J. After the episode's ordeal, Otaru asks Lime and Cherry "Haven't we forgotten something?" but they finally decide it doesn't matter and leave. Cue Hanagata tied to a water mill, being tortured by Baiko and Tamasaburo.
  • In the first volume of Yawara! A Fashionable Judo Girl, Jigoro mugs a member of the high school Judo club so that Yawara will be forced to take the boy's place in an upcoming match. When Yawara later asks how he managed to trick her into participating in the match, he suddenly remembers that the poor boy is still Bound and Gagged inside the P.E. storeroom.
  • In the climax of the fight against Iroha in Sumomomo Momomo, Momoko and Iroha have a moment of understanding and vow to work together rather than counter to each other. The two celebrate their friendship and go home...promptly forgetting that, as bait, Iroha had tied up Koushi, the man the two were fighting over, and had him dangling over a pool with multiple highly venomous sea snakes. They manage to get him as the two run off.
  • An episode of The Kindaichi Casefiles had Kindaichi framed for murder (again), although this time he really did land in the slammer. After Akechi solves the case, he takes off for the night, while Inspector Kenmochi goes with a couple of other officers to celebrate the solving of another crime. Kenmochi has a brief recollection about forgetting something, but ultimately just shrugs it off. Miyuki, meanwhile, was Out of Focus, thinking that Kindaichi stood her up on their date, and goes out on her own, not knowing what actually happened. The last scene of the episode has Kindaichi apparently alone in jail shouting for his innocence, even solving the crime himself (having come to the same conclusion as Akechi did).
  • Nagasarete Airantou
    • Suzu was secretly tailing her pet pig Tonkatsu (who wanted to do an errand for her by himself) when she comes across Shinobu, lost again and weak from hunger and dehydration. Since she doesn't want to lose Tonkatsu's trail, Suzu promises to help Shinobu once she gets back, but Suzu never did return for Shinobu.
    • Another chapter had Ayane tied up by her sister Machi as a quick gag. By the time Machi finally gets back to her, Ayane had already untied herself, although she was also cleaning up some sort of mess (implied to be a Potty Failure).
  • Digimon Adventure 02
    • The Digidestined opt to stay in the Digital World for an indetermined amount of time until they beat the Digimon Emperor. They make the excuse of going on a camping trip so their parents wouldn't get suspicious. Davis' older sister Jun decides to join the trip since she learned that Matt is going to be there. Matt ditches her the first chance he gets, however, Jun eventually reaches the campground in the end, to everyone's astonishment.
    • In one episode, Davis is the only member of the Five-Man Band whose partner Vmon doesn't have an Armor Digivolution that can chase after the Digimon Emperor's flying fortress (Yolei, TK and Kari's partners can fly, Cody can keep up in the sea with Submarimon). Davis and Vmon only manage to catch up at the end of that same episode.
  • This is a Running Gag in Boarding School Juliet, and it can happen to anyone, even the main characters. Notable examples:

Scourge, however, is unaccounted for, and his absence is brought up, with Cyclonus trying to find him to say good-bye and Sky-Byte seeing a Sweep and commenting on it looking like a friend he knew (implicitly Scourge because the Sweeps are clones of him, and his name is a Mythology Gag for Sky-Byte).
    • Eventually, Scourge was confirmed as having died somewhere during the Chaos mini-event. In an author's note. For a completely separate out-of-continuity series.
    • Played for both laughs and drama with Tailgate, who at the beginning of MTMTE has fallen down a tunnel, his legs and chronometer are broken, and he's concerned with missing "the launch" (which the audience will presume is the launch of the Lost Light, which kicks off the series). He decides to detonate his fuel reserves to blow a hole in the ceiling and call for help, but due to the broken chronometer he keeps passing out and has no idea how much time is passing. Eventually he succeeds, only for him and the reader to learn that he was down there for six million years, the launch he was late for was the original Ark, and nobody ever noticed he was missing all this time.

    • In "If You Can't Take the Heat...", the Screaming Gophers trick Heather into the freezer and lock her up in there because she's bossing them around, and not in a way that'll make them win the cooking challenge.

  • The G.I. Joe: Sigma 6 episode "Race" ends with the Joes forgetting that they've left behind Tunnel Rat.
  • The "What If...Zombies" episode of What If...? (2021) started the same way Avengers: Infinity War did, with Bruce Banner crash-landing on the Sanctum Sanctorum of Doctor Strange. What diverges from the film is that, before he could warn his fellow heroes of Thanos' impending arrival, Bruce finds the Earth ravaged by zombies. Bruce completely forgets about the cosmic threat and never got to tell his fellow survivors before seemingly sacrificing himself. At the end of the episode, the remaining survivors fly to Wakanda, unaware that Thanos (also now a zombie) awaits them there...

    Real Life 
  • POWs that continue to be held long after a conflict ends — for example, Americans who continued to be held in Vietnam, or even North Korea — are a grim real-life example. One could also say the same of the children of local women impregnated by soldiers of occupying armies during wartime.
  • When Julius Caesar marched on Rome on his return from the Gallic wars, Pompey's government fled into exile — leaving the entire contents of the national treasury behind them. D'oh!
  • David Bowie once gave a live stage performance, at the end of which, during his final number, he was picked up, in his chair, by a "cherry Picker" and swung out over the audience; at the end of the number, the lights went out, with Bowie still in mid-air, as the audience got up and went home; the theatre crew locked up and went out to a bar; it was only after several drinks that they realised that Bowie was still in the theatre, in his chair, at the end of the cherry picker arm, fifty-plus feet above the floor of the auditorium; "Were you going to leave me up here all night, you bastards?" was his first question as they frantically returned to the theatre.
  • Similarily to the above example, one scene in the Doctor Who-episode "Mark of the Rani" required Colin Baker (who played the Doctor) to be tied to a large pole for a Tribal Carry in the middle of a forest. However, because Baker wore a support harness, untying him every time they reset the stage proved too time-consuming, so the crew just laid him down on the forest floor between takes. When it started to rain, the crew packed up and left to film a different scene in another location...only to realize after half an hour that they'd left Baker behind in the forest, still tied to the pole!
  • Apparently, My Chemical Romance has occasionally left their guitarist Ray Toro at truck stops while on tour.
    Ray: And the band's kinda driven a couple miles down the road, and I'd have to call them on my cellphone and it's like, "hey...what's up?" And they're like, "hey, how's it going man?" I'm like, " notice something's missing from the van?" And they kinda look around and go, "ahh, shit."
  • In Empire of Dreams: The Making of the Star Wars Saga, Kenny Baker recounted that, while filming, the cast and crew would on rare occasions forget he was inside the R2-D2 outfit (which could not be taken apart from the inside) and leave to take their lunch breaks. But, he said, someone would usually remember he was in there and come back to let him out.
  • Every summer, babies get rescued from the back seats of hot cars because their caregivers forgot they were there. Tragically, such rescues aren't always in time.
