Deleted Scene: At 5:39 pm, Angela (Portia Doubleday) continues to sit in front of her TV and watch news coverage of the attacks. Mr. Robot (Christian Slater) knocks on the door, startling her and demanding to be let in. She does so hesitantly and he demands to know who changed the plan. She denies any knowledge, although he insists she and Tyrell (Martin Wallström) had something to do with it, despite Angela's insistence that she spent the weekend with Mr. Robot. The news anchor grabs his attention, telling of a supposed second attack coming in 24 hours. Mr. Robot wants to meet with Irving, demanding Angela's form of contact. She retrieves a phone he gave her, after asking him to not touch the TV. As Mr. Robot uses her laptop to trace Irving's location to the car dealership, Angela becomes transfixed by the news. She rewinds a moment when the anchor puts the recent death toll at 3,817, playing it again and again and repeating the number aloud. Mr. Robot finds it strange and leaves.
