Another Theory I Had Was That Linguini Was Kind Of Dumb Because He Was Thrown Around By The Aliens Everywhere - Tumblr Posts

So when i was younger i used to watch Ratatouille because i just loved it a lot

And as it is with Pixar movies, there was a short playing before the movie and as you all know, it was about some aliens trying to kidnap some guy.

Because child me was stupid i didn't know that shorts don't really relate to the movies themselves, so when Linguini said his mom disappeared i just assumed she got kidnapped by the aliens from the short lmao
