'Mr. Robot' Review: "Stage 3" - The Workprint

"They own the FBI" is the message Mr. Robot leaves Elliot on the mirror which kickstarts Elliot's journey in this episode. After last week's guilt tripped journey with Trenton's brother culminating in Elliot finding meaning again in his life, Elliot finds some information read by Mr. Robot the night before: Trenton's e-mail and Tyrell's surprising release from the FBI. Meeting at the old F-Society arcade, Elliot and Darlene discuss the details of Trenton's e-mail, which was sent to Elliot after she and Mobley were murdered by the Dark Army. It details a way of undoing 5/9, discovering that Leslie Romero, the older hacker from seasons 1-2 that was killed by a'stray bullet', had exported the encryption keys used in the 5/9 hack as a safety precaution. But all his files were now stored in the FBI Sentinel network system after his death.
