User blog comment:Weavillain/Why I Believe Leni SHOULDN'T Have a Mental Disability/@comment-1650307-20171007163007

Completely agree. There is no way that Leni has a developmental disability. If anything, saying that she has something like autism canonically would not make sense since she is pretty sociable and it would bring forth that stereotype of "all autistic people are stupid", which is the last thing that they want.
