You gotta wonder if the shot of the "theater" the 4 personalities and then rolling film before the real Elliot opened his eyes was a way of implying that they were giving him all the knowledge and memories he missed while he was out. Specially giving The Mastermind final monologue about how we all changed the real Elliot. It didn't seem he was going to be thrown to the real world without any knowledge of anything.
NOW, OG Elliot does have a personality disorder and a really fukked up childhood so no matter what happened he's still gonna struggle like a motherfukker. But that was the point...don't give up and keep going.
This shyt really was End of Evangelion. Blessmail took some of Anno's fukked up ideas - that he had while he was suffering from deep depression - and executed them in a different and beautiful way. As I said before, Sam is the GOAT Evangelion stan, I can't be convinced otherwise
I read a pretty dope post on Reddit about it...
Okay, so from my understanding, Esmail wrote the story in such a way where everything still happened while maintaining the twist that Elliot was another alter. He did this by saying that mastermind Elliot enacted a master plan that had been dreamt up by the real Elliot, as a reaction to the real Elliot’s pent up rage about his father, and therefore society. He basically became a superhero, so when his real self returned, it was to a world that was ridden of evil. Mastermind Elliot did his job, assisted by Mr. Robot, and the real Elliot has returned to a “better” world than before he left. Therefore bang, happiest ending. Sound about right?
