* Just before their first encounter with the Brain Trust, Achilles of the [[GlobalGuardiansPBEMUniverse Global Guardians]] teaches his teammate Arachne how to use a pick to open a set of handcuffs while her hands are cuffed behind her back. By the end of the story, she's used this brand new skill ''twice''.
* This sometimes happens in ''SurvivalOfTheFittest'' with the profiles of the characters. Newbies often try to cram in as many potentially useful skills as possible (such as survival training, firearm proficiency and martial arts. Made ridiculous when [[FridgeLogic you consider]] that the characters are ''supposed'' to be [[OrdinaryHighSchoolStudent Ordinary High School Students]]

** In the novel ''Ayla and the Tests'', five-foot-nothing Phase is pushed by a teacher to use his particular Warper power to take over a size-Warper's power. In a different novel, "Boston Brawl 2", Phase figures out how to use this trick to ''beat the holy crap'' out of a forty-foot giant.
** And an awful lot of what the teenagers learn in martial arts class. Aquerna learns a couple cool moves, plus LeParkour, and she uses those in every one of her own stories.

* In ''WebVideo/DoomHouse'', Reginald P. Linux's ability to throw the doll, first demonstrated when he's trying to remove the doll from his new house, comes in handy later when he must fight [[spoiler: the terrorist]].
* ''WebVideo/TheAutobiographyOfJaneEyre'': It's established in the first episode that Jane is a nurse, but she's pursuing a new degree and becomes a tutor. She also showed her competence when Mr Rochester had a minor car accident and sprained his ankle. Her nursing ability came ''really'' handy later in episode 13 "Crash" when Mr Rochester was mysteriously injured and was bleeding quite a lot. Jane fixed his arm real nice.
