User blog comment:Gumball2/Is Leni Really Stupid?/@comment-31563773-20171003141531

Leni is dumb, but it depends on the episode and whose writing it. I think she does have some form of ADHD after doing a bit of research, seeing as her reactions seem close to what I found. I was thinking ADD, but it said people like that tend to be quite cynical while having low attention spans, but that doesn't sound like Leni since she's quite happy. However, I still like the idea of that she has to take pills to keep it in check, but forgets to do it.
