@Gumball2 I to believe that she might be on the autism spectrum, but considering the number of times her siblings have often shown small amounts of frustration with her remarks where she often interprets things said to her literally (such as misinterpreting a steak-out as meaning they are literally out of steaks), would kind of fly in the face of the shows general attitude of tolerance (such as not treating Clyde's dads and Luna's sexuality or CJ's down syndrome as a big thing). Granted if a later episode were to reveal this to her siblings and they feel kind of bad for not realizing it, that could be a good twist on the show's theme of tolerance.
