Spoilers for this episode and earlier episodes.
Elliot's call with Tyrell offers no clear account of the missing days. Mr. Robot ends it, and news of Gideon's murder deepens Elliot's panic. He takes Adderall obtained through Leon, hoping that staying awake will prevent Mr. Robot from taking over. A terrifying vision of men forcing cement into his mouth gives way to Elliot vomiting the pills. He swallows them again, refusing to let Mr. Robot decide what happens to him.
The drugs keep Elliot awake for days and briefly make him feel free of his unwanted companion. That relief breaks down as exhaustion and distorted perceptions take hold. At his church group, he launches into an angry speech about religion before leaving. Ray later returns Elliot's journal and talks about the loss of his wife. He offers a way to talk through what Elliot is carrying, while continuing to seek help with his computer problem.
