"I'm pretty far from OK"

[Overbrook]

OK, who had even an inkling that Elliot was Mr. Robot?

I gotta admit, I did not see it coming, but it makes sense now.

[Sect 236]

The episode where Eliot is detoxing in the motel and Mr. Robot says "I'll always be with you," or something like that, was when I first began suspecting.

Also, in hindsight, the fact that the show is called "Mr Robot" but the main character is Eliot was a pretty big clue.

I only watched the first few episodes. In retrospect it doesn't surprise.
