They didn't show it happening — nowhere in the dialogue or narration was it explicitly stated that it happened — but the evidence that it did happen (though indirect) is pretty clear just the same.
Maybe it happened before the story proper, in the backstory. Maybe it happened in the interim between sequels (or even scenes). Maybe it was going on in the background just out of the audience's sight.
An Implied Trope is where the author leaves a trail of clues to hint that a trope happened without actually showing it; the clues are taken from Subtext. This can be done by showing the build up to a trope, by showing the after-effects, or both. It is something between playing a trope straight and subverting it. As with a Subverted Trope, an Implied Trope assumes the audience is familiar enough with the trope that they'll be able to understand what's being suggested, but rather than defying those expectations, the work uses them to create the same effect as the trope while leaving the details up to the audience's imagination.
However, an Implied Trope can create an effect akin to dominoes. If A implies B, then C implies D, which implies E, which implies F, which... Yeah. Tropers can sometimes take things too far and infer more details than they should.
When something is implied because it's inappropriate, that's Getting Crap Past the Radar. When multiple tropes can be inferred, but they can't all have happened together, you have an Ambiguous Situation. Not to be confused with an Invoked Trope.

- But You Were There, and You, and You in Tim Burton's Alice in Wonderland (2010). We know that Alice dismisses her first visit to Wonderland as a dream.

- Heroic Suicide in The Thing (1982). Fuchs is found as a charred corpse. There was no reason for the Thing to kill him off instead of assimilating him, so it's safe to assume that he did it to himself in order to avoid being assimilated and thus being used to assimilate the rest.
- Agents of S.H.I.E.L.D. implies that Coulson Came Back Wrong.
- Your Approval Fills Me with Shame in Game of Thrones: Jorah Mormont explains to the exiled former prince Viserys that the death sentence he fled was for selling poachers to a slaver, something that's left Jorah with a lasting sense of shame. Viserys replies that under his reign Jorah wouldn't be punished for "such nonsense." Jorah's expression implies that he'd rather face the punishment than live in the kingdom Viserys would build.

- Retired Monster is implied with many of the Wesen. In the second episode, when one of the Jägerbärs is told that his family is performing the traditional manhood ritual (which involves hunting down and killing someone), the first words out of his mouth are, "What? No one does that anymore." It also explains why Blutbaden, whose hungry urges are triggered by the color red, haven't eaten everyone. For other Wesen like Spinnetods, they're rare enough that either they're retired like Charlotte or dead because of the particular demands of their biology aren't compatible with a normal life. There's even a Monsters Anonymous program that Monroe participated in.
- Scrubs: In "My Princess", Dr. Cox tells about his day at the hospital to his son in the form of a bedtime story. In the story, a maiden being terrorized by a monster is saved in time and lives Happily Ever After, while in reality, it's a fatal disease and JD and Elliot are able to diagnose the patient. When Jordan asks if the story really had a happy ending, he replies "that's the way I'm telling it", implying that she didn't survive.
- In the series finale of Seinfeld, Susan's parents are seen purchasing a handgun during the trial, implying that they intend to carry out a Vigilante Execution on George as retribution for Susan's death if the gang is found not guilty.

- Bestiality Is Depraved: In the same game, you get Cook-Cook, flamethrower wielding psychopathic rapist, who goes berserk when you kill his pet brahmin (mutated cow), and who really stinks.
- Driven to Suicide or Death by Despair: In one of the many motels you can visit in the game, you may stumble across a room with a briefcase full of pre-War money and clothes. When you investigate the bathroom, you'll find a skeleton in the bathtub, surrounded by untouched doses of Jet and Med-X and some empty syringes. It's hard to determine whether or not the drug overdose was deliberate, but it's almost certainly what ended his life, and given the state the world was left in after the War, it's not surprising some people would try to seek some form of refuge from reality in one way or another.

- The X-Universe series doesn't list the sizes of their ships specifically, but the jumpgates are known to be about a kilometer in diameter and travel speeds are given in meters per second.
