Nobody's invincible, no plan is foolproof, we all must meet our moment of truth...
All for Nothing: Irving shows Mr. Robot a lavish rooftop party where he must go to clean up the aftermath of an overdose. As Mr. Robot gazes on, Irving informs him that those people are just a small contingent of many who have bought and paid for Mr. Robot's revolution. As he walks toward the building, Irving remarks that "nothing can stop these shindigs."
A Million Is a Statistic: Averted. The episode goes out of its way to remind you that stage two was horrifically damaging not just to human lives, but to the setting.
Back for the Dead: After six episodes and a year-long off-season gap, Mobley and Trenton return only to be summarily executed by the Dark Army in the end.
Darkest Hour: Pretty much every character on both sides of the spectrum is having a really bad day. Elliot is dealing with his failure to stop Stage Two, Mr. Robot is told the truth about his revolution by Irving which greatly affects him, Angela has completely fallen off of the edge of sanity with Darlene lost and alone in the aftermath, Tyrell is informed of Joanna's death by Santiago, who threatens Tyrell's son to ensure that he remains quiet, Price is reeling from the cyber-bombings and emasculated by Zhang into staying the course, Dominique is depressed by the possibility of Whiterose getting away with everything, and Trenton and Mobley are taken hostage by Leon, who eventually hands them over to Grant and their subsequent demises.
Downer Ending: Mobley and Trenton are sacrificed (against their will) by the Dark Army and posthumously scapegoated into perpetrators of the cyber-bombings. Meanwhile, Elliot is grief stricken by his failure to save any lives and is eventually sealed away by Mr. Robot, who tracks down Irving and learns that none of what fsociety accomplished ended up mattering in the end. The revolution has been bought and paid for, and Mr. Robot was just another puppet of the Dark Army. As the FBI take over, Dominique resigns herself to the white-board, crossing out Mobley and Trenton's pictures and adding Whiterose as a prime suspect. Despite this, she is doubtful that anything can be done to stop the Dark Army.
False Flag Operation: The Dark Army implicate fsociety as Iranian terrorists who carried out the cyber-bombings through extensive stage-setting and the use of a funded patsy.
Genre Shift: Starts as a Tarantino-esque black comedy with hostages, turns into a neo-noir psychological thriller with dysfunctional relationships, and evolves into a conspiracy/paranoid thriller reminiscent of Homeland and 24.
Idiot Ball: Trenton can't drive because she never learned how to in an urban environment. Acceptable. Not acceptable: swerving back and forth in an escape and somehow crashing into a lone rock when you have 359 other degrees to feasibly choose from.Shockingly, this event puts them right back at square one, with one opportunity less.
Madness Mantra: "I don't know if I can say it... I don't know if I can say it... I don't know if I can say it..."
The Reveal: Angela was the "individual" that Price mentioned in the season one finale, and has always been an object of manipulation by Whiterose, who entrusted Price to do it. As it turns out, Price could not, and Whiterose stepped in behind Price's back. Only this time, it would be a deliberate emotional attack, Foreshadowing as we would later discover.
Sanity Slippage: Angela goes through one after the attacks occur and spends the whole afternoon justifying that she can bring the victims back by rewinding the news report repeatedly, with Darlene trying to calm her down.
Shoot the Shaggy Dog: "eps1.5_br4ve-trave1er.asf" has some serious competition with this episode for the most devastating moment in the show.
Tyrell learning of Joanna's death and his son's status. Santiago uses this information to keep Tyrell in line should he think about rebelling. Unable to accept the truth, Tyrell begins sobbing and wailing. It is hard to not feel sorry for him in this scene.
Not only do Mobley and Trenton die bawling and pleading for their lives, they are later positioned among Irani flags, fsociety gear, and false plans for a second attack on both of "their" terminals just to cap off a false flag operation. In the end, their names are tarnished, and as observed on Dominique's white-board, they were at the bottom of the totem pole.
Angela's mental state. She has become a zombified shell grasping at straws to justify her guilt while simultaneously losing grasp on reality.
