Does it ever go in to more detail on why Darlene sided with the FBI? It seemed like they were leading up to something at the end of S2.
Mr. Robot: I think the implication is that when Dom showed Darlene the board they had she realized they were way closer to the truth than she had previously thought, having connected Elliot, Darlene, and all of fsociety already and is acting to protect herself and Elliot because their one out is the FBI is under the impression that Tyrell is the mastermind.
