Mr. Robot, Season 1

Tyrell Wellick:
How long has this been going on?

Elliot:
I don't know.

Tyrell Wellick:
And what is it that you're doing exactly?

Elliot:
Encrypting all the files, all the Evil Corp's financial records will be impossible to access. The encryption key will self-delete after the process complete.

Tyrell Wellick:
What about the backups?

Elliot:
I took care of that too. China...

Tyrell Wellick:
Steel Mountain? Of course, even when we went redundant.

Elliot:
I hacked the AirDream network. I was in all of them.

Tyrell Wellick:
You really thought of everything. Who else was involved?

Elliot:
Just me.

Tyrell Wellick:
Well, now it's you and me. I've always told we'd end up working together, Elliot. But still, I have to know. Why did you do it? What did you hope to accomplish by doing all of this?

Elliot:
I don't know. I wanted to save the world.
