what if the Fight Club similarities are even more intentional than we think? If Fight Club exists in this world, it's likely Elliot would be a fan. Maybe he kinda subconsciously models his worldview and certain things in his life after it.
Hello, anonymous friend! Do you mean like the actual Fight Club universe? Project Mayhem, in the same universe as the Mr. Robot universe? Is that what you mean? or do you just mean the movie?
tl;dr: I could absolutely see Elliot having read and/or seen Fight Club, and that the concepts introduced therein could be incorporated into his consciousness/worldview.
