Mr. Robot, Season 4

"Krista":
In order for you to fully hear the truth, first we need to discuss Elliot's Dissociative Identity Disorder. The first personality was created the day Elliot jumped out the window -- the protector personality. The one Elliot created to replace his father. To protect him from intolerable situations. Mr. Robot. Later in life, Elliot created the Mother personality. The persecutor, blaming Elliot for the abuse. Insisting that he needed to pay for it. Not long after her came Elliot's younger self, who emerged to handle the abuse he couldn't tolerate. And with that, he created his own family... of sorts.

Elliot:
[to the viewers] I guess she doesn't know about you.

"Krista":
[looks to the camera] I know all about them, too. The voyeurs who think they aren't a part of this despite being here for all of it. And for a while, we thought we had identified all of Elliot's personalities. But there's another one who came about not too long ago.

Elliot:
I don't wanna hear this again.

"Krista":
The truth about who you are? I think it's time. [to camera] Even they agree with me.

Elliot:
I know where you're going with this! It's not true!

"Krista":
It's okay. I know why you did it. Your heart was in the right place. You wanted to shelter him, which is why you changed his past.

Elliot:
I... I wasn't changing anything, that's... What I thought happened.

"Krista":
But it was his future you really wanted to protect, wasn't it? That's why you went to such great lengths to take down all the evil that surrounded him in the real world. That's why you formed fsociety. You loved him so much, you wanted to save the entire world so you could make it better for him, no matter the cost. That's why you hid him here. Turning his harsh reality into a fantasy. Trapping him an endless loop, to keep him safe until you were ready.

Elliot:
I don't remember any of this? Why should I trust you? You've been wrong before...

"Krista":
You're right. She was wrong. Krista never quite figured it out, did she? She never realized she was talking to the real Elliot. She didn't realize she was always talking to you. A personality created to carry Elliot's rage. The vigilante hacker Elliot always imagined being. THe one that sought vengeance. The personality that had gained so much control, he forgot. He forgot he was only just another personality. The Mastermind.
