History Fanfic / MySisterLeni

* AmbiguousDisorder: The fanfic starts out intentionally vague about Leni. She's different from other kids - what with her poor social skills, hyperfocus, etc - but nothing is initially discussed. It isn't until several chapters in that it is revealed that she's on the autism spectrum.

** The fanfic is based on the common {{fanon}} theory that Leni has a psychological/neurological/developmental disorder which is why she acts like a DumbBlonde. It does seem a bit inconsistent with her characterization in later episodes though.

* TragicStillbirth: [[spoiler:Leni's namesake, Lori's twin sister]]. Leni only found this out after going through an old diary.

* {{Fangirl}}: Leni is very fond of ''WesternAnimation/TheLandBeforeTime'' series and is especially into Ducky. Her [[CharacterTic signature "raptor arms"]] from throughout the series comes from her imitating Ducky. She also developed an interest in ''Princess Pony'' [[PeripheryDemographic well passed the age where it would have been socially acceptable]], [[ClosetGeek although she hides that from others]].

* TragicStillbirth: [[spoiler:Lori's]] twin sister was born stillborn. Leni only found this out after going through an old diary. [[spoiler:She's named after Lori's twin]].

* DoubleMeaningTitle: The title could refer to either this Leni, or [spoiler:her namesake, Lori's stillborn twin]].

* DoubleMeaningTitle: The title, at first, clearly refers to Leni. However, with the events of Chapter 16, it could also easily refer to [[spoiler:the original Leni Loud, Lori's stillborn twin, and thus could mean that the rest of the Loud family is retaining the original Leni's memory with the Leni they ''do'' have]].

* {{Fangirl}}: Leni is very fond of ''WesternAnimation/TheLandBeforeTime'' series and is especially into Ducky. The "dinosaur pose" she does in several episodes comes from her imitating Ducky. She also developed an interest in ''Princess Pony'' [[PeripheryDemographic well passed the age where it would have been socially acceptable]], [[ClosetGeek although she hides that from others]].

* ImplausibleHairColor: Lincoln was born brunet, but his hair started paling at a month old.

* DoubleMeaningTitle: The title, at first, at first clearly refers to Leni. However, with the events of Chapter 16, it could also easily refer to [[spoiler:the original Leni Loud, Lori's stillborn twin]]

-->''When Lynn and I first saw that one in the baby name book, we were surprised that it even existed; the only spellings we knew were 'Lenny' and 'Lennie' and they were both for boys. We originally disregarded it in favor of more traditional girl names like Lauren or Linda. But in the end, I went back to Leni because it's rare. I want her to truly feel unique, that she is one of a kind.''

* ThemeTwinNaming: [[spoiler:Lori]] had a stillborn sister named [[spoiler:Leni]]. Leni lampshades the confusing aspect of having two similarly named siblings.

* AlternateUniverseFic: A few details in the universe are different from canon, such as Luan not going too overboard during April Fools or Lisa not working with dangerous chemicals.

The fanfic begins with Leni starting kindergarten. Throughout 53 chapters it tells the story of Leni's childhood and how she relates to others.

* {{Expy}}: Leni watches an episode of ''My Pretty Pony'' featuring a curly maned pony named Rosy Cake and a purple pony named Twily. They're references to Pinkie Pie and Twilight Sparkle of ''WesternAnimation/MyLittlePonyFriendshipIsMagic''.

* TakeThat: Just hearing the title of ''[[MyLittlePhony Princess Pony]]'' makes even most of the girls in Leni's kindergarten class cringe. Judging from the timespan, it's riffing off of ''WesternAnimation/MyLittlePonyG3''.

* DisabledInTheAdaptation: The fanfic is based on the common {{fanon}} theory that Leni has a psychological disorder which is why she acts like a DumbBlonde. It does seem a bit inconsistent with her characterization in later episodes though. Lisa is also later revealed to be autistic as well, but how it manifests wit her is vastly different.
