History Fanfic / MLPTrinity

* DeterminedWidow: Sweetie Finemare pursues her scientific career and raises two little fillies alone after the death of her first husband.

* ILoveNuclearPower: Horribly [[AvertedTrope averted]] -- Sweetie's under-shielded radium-based quantum-mechanical experiment that she and her OneTrueLove Rich Greentree perform in 1936 leads to his developing cancer by 1938 and dying at age 25 in 1940.

->Oppenhorser: "Now I am become Death ... the Destroyer of Worlds"

** Because many Ponies thus lived whose Human analogues would have perished in those wars, [[DieselPunk technology is somewhat more advanced]]: for instance, the atomic bomb is developed by 1938 and nuclear fusion reactors by the 1960's. As discussed in FanFic/AMeetingByMoonlight, only their relative lack of initiative stops the Ponies from colonizing the Solar System in the late 20th century YOM.

* [[HeroOfAnotherStory Heroine Of Another Story]]: After her death, Nurse Raindew's soul is gathered in by the Cosmic Concept of which it had been a facet ... [[spoiler:Kindness]]. In other words, [[spoiler:Nurse Raindew was an earlier Incarnation of the same being who would later manifest as ''Fluttershy'']].

* SuperweaponSurprise: Amareica averts the outbreak of war by inviting representatives of the aggressor states to their equivalent of the Trinity Test in 1938.
