Plot summary
Elliot declines a job offer from Tyrell Wellick, interim CTO of E Corp. Increasingly paranoid, Elliot uses more morphine than normal. Darlene visits him at home to bring him to fsociety, surprising him. Mr. Robot and fsociety want Elliot to destroy an E Corp offline backup facility called Steel Mountain by hacking an adjacent gas plant and causing an explosion. Elliot backs out because he does not want to risk lives. Shayla is Elliot's drug dealer and friend. When Elliot notices Fernando Vera, Shayla's supplier, abusing her, Elliot collects evidence against Fernando and turns him in to the police, despite Shayla's explicit instructions not to.
Meanwhile, Cisco, an unknown associate of the Chinese hacker group The Dark Army, hacks Ollie's home computer with a compact disc (CD). Elliot and Mr. Robot discuss Elliot's falling out with his father: Elliot told his mother of his father's terminal illness, despite promising his father he would keep the illness secret. Mr. Robot pushes Elliot off a railing onto the rock-strewn beach below as punishment for not keeping his father's secret.
