''Some fans try to diagnose Leni as having autism due to the way she holds her hands, how she's generally inattentive among other reasons. Having Asperger's myself, I found this theory disgustingly offensive. Really, if anything, Leni doesn't meet most of the criteria. For instance her social skills are pretty top notch, she has no issues with sound, she can very clearly express empathy, etc. If any of the kids were to have at least Asperger's, I'd have to personally say the most likely candidate is Lisa.''

It would make sense to see Lisa with Asperger's, but also Luan too. I think this because she talks too much about her biggest interests (which are stand-up comedy, pranks and telling jokes), which makes her siblings mad for the most part, and some kids with Asperger's like me are prone to talking about what they like too much.
