Pat was freaking out because he couldn't tell if we live in a simulation or not. After Pat forces Ben to watch the entire Matrix trilogy, he makes Ben explain the 'Brain in a Vat' scenario. Is any of this real? Can we wake up from this nightmare? And what does all this have to do with 17th Century French pervert Rene Descartes? Pat learns that Cipher kind of had a point, Morpheus is an asshole, and that the most famous quote in the history of philosophy, "I think therefore I am," was Descartes, not Shakespeare.
