I’ve made many Pixar Theories in the past, and even linked a ton of them together into one massive video that was three hours long. Today, I contemplate the logic behind Pixar’s multiverse, and how EXACTLY shared universes work here... But this inadvertently answers millions of other questions. This theory spans EVERYTHING. What is Horst’s Backstory in Ratatouille? Who is Russell’s Dad in Up? What’s the deal with BNL, A113, and the Pizza Planet Truck? HOW DOES IT ALL COME TOGETHER?! Well, prepare yourself, because this "Nest Theory" video is absolutely absurd, and it's merely the beginning of YET ANOTHER 3-hour video.
