I mean, Mr. Robot might still not be "real" in the sense of being alive. Although the final scene sure leaves the question of why the fukk, after the big revelation, would an alter ego want to set things straight, maybe Mr. Robot is a different guy and Elliot just projected his dad's image on him....shyt's weird as fukk
. But dude at the very least existed and that's something I didn't think was possible either.
Mr Robot shoving Elliot down to the beach when he told the story about his father throwing him out of a window when he didn't keep his cancer a secret is a lot more
now.
I love being wrong with shows like this though, I speculate and just enjoy the ride
