Explain, Explain, Oh Crap

Bob has the situation under control, and is explaining it to his partner, Alice. While he initially thought everything was fine and going to plan, it's only once he stops to think about it and hears himself say it aloud that he realizes how much trouble he and Alice are really in.

Essentially, a case of in-universe Fridge Logic catching up to the characters, can be played for laughs or drama. Can be triggered by the listening party's Let Me Get This Straight... putting a new perspective on Bob's explanation.

The Oh Crap can also be simply that there really is No Time to Explain.

"Cain: "But she's not nearly as accident prone as she's supposed to be. I'll grant you she fell down an ambull tunnel once, and there was that incident with the frag grenade and the latrine trench, but things tend to work out for her. The orks on Kastafore were as surprised as she was when the floor in the factory collapsed, and we'd have walked right into that hrud ambush on Skweki if she hadn't triggered the mine by chucking an empty food tin away..." My brain finally caught up to what I was saying and I trailed off rather lamely. "Well, you know how soldiers exaggerate these things.""

Mal: Wave your arms around. Jump up and down. Divert the nav sats to the transmitter. Whatever. Wash: Divert the - Right! Because teenage pranks are fun when you're about to die! Mal: Give the beacon a boost, wouldn't it? Wash: Yes, Mal, it would boost the signal. But even if some passerby did happen to receive, all it would do is muck up their navigation. Mal: Could be that's true. Wash: Damn right, it's true. They'd be forced to stop and dig out our signal before they could even go anyplace.

Come to think about, his name was... it was you. Damn..."

However, in the midst of an in-depth discussion of said probes with the player, they realize that, due to an attempt to get the probes to replicate faster (by changing the priority of replication to 999, the highest setting on the dial), they have inadvertently caused their probes to attempt to procure raw materials for replication from ANYTHING they encounter, with a special priority on alien ships. This has effectively transformed their peaceful exploration fleet into a Horde of Alien Locusts.
 * In Fallout: New Vegas, you can meet an Outlaw Couple who think that an antique machine gun makes them dangerous enough to go on a crime spree through the Strip.

 * Mordin Solus' introduction and Establishing Character Moment in Mass Effect 2 begins with Mordin performing a Sherlock Scan on the newly-arrived Commander Shepard and his/her team, while verbalizing his inner monologue; assuming the player doesn't interrupt him, he determines that the characters aren't from the area, too well-armed to be refugees, too informally-dressed to be any of the local mercenaries, and that they aren't there to wipe out the Vorcha or to investigate The Plague's usefulness as a bioweapon. Eventually, he decides that they must be looking for someone important, someone with secrets... and then realizes that they're almost certainly looking for him.
 * It happens again a minute later when Shepard explains that he/she was sent by a privately-funded human group to recruit Mordin. Immediately, Mordin starts sorting through a long list of possible candidates for the aforementioned group. After disregarding the Alliance, the Spectres, the Terra Firma Party, he finally realizes (with some shock) that the most likely candidate is Cerberus, a terrorist group with human-supremacist leanings.
