2. You're My Sister
The final two entries on the list provided the show's two central mysteries, and led to large fan speculation about who each character actually is in the narrative. Elliot's mental instability, the sneakiness of those around him and the unconnected dots generated many theories, and intriguingly the show answered each of them in episodes eight and nine - leaving the finale to stand on its own, separate from those other enigmas. The first, and one that had arguably been pretty well hidden (with the clues being fairly subtle), was the revelation at the end of episode eight that fellow fsociety member Darlene is a lot closer to Elliot that he had originally thought. She tells him she loves him, and he kisses her. Revolted, she pulls away and demands that he remembers who she is. "I'm your..." "...Sister. You're my sister!" he realises, suddenly. Given that he clearly had no idea, it is shocking for the viewer. What? His sister? How could he not know? How does he know now?! Elliot's mind begins to unravel, and he rushes home. Both Elliot and the audience are deeply confused. Why can't he remember any of his life? He searches through his files for something about himself, and he finds an unmarked CD. Loading it reveals hundreds of pictures of Elliot as a child with his apparently deceased father... Who is Mr. Robot. Suddenly there's a knock at the door. It's Mr. Robot. "We need to talk", he admits, as the episode concludes. Genuinely mind-blowing stuff. Is Darlene actually Elliot's sister? Is Mr. Robot Elliot's father? Isn't Elliot's father dead? Why doesn't he remember any of this? Episode nine couldn't arrive quickly enough...
