'Mr. Robot' Season 2 Spoilers: Why Is Elliot In Jail? 3 Theories

What started out as a continuation of the previous episode ended with a big surprise, albeit one that has been predicted by some fans online. Edward (Christian Slater) tried to get to the same point. Elliot has been asking the image of his dead father on his head to let him know what happened the night he executed the hack on E Corp for a while now, and in the last episode, he finally budged. After asking whether he did it – "it" pertaining to killing Tyrell Wellick (Martin Wallstrom) – Edward finally gave him what he wanted. Finding out that he did kill Tyrell was not enough, so Elliot asked how he did it.
