Oliver must fight off impeachment charges for covering up Billy's murder
- Aesop Amnesia: Felicity has forgotten the consequences of hacktivism from her college years as she joins up with Helix full time.
- Artistic License – Law: To impeach a public official does not mean to remove them from office; it means to put them on trial to be removed from office. So Oliver was in fact impeached; he just wasn't convicted in the end.
- The Bad Guy Wins: Oliver's press conference means the city no longer sees the Green Arrow as a hero, just like Prometheus wanted.
- Bait-and-Switch: Dinah recovers a small piece of Vigilante's mask and then Adrian Chase convinces her to give it him to log into evidence, making us think that he's Vigilante, trying to recover evidence that could point to his identity. Then we learn that Chase is Prometheus, not Vigilante.
- Bittersweet Ending: Oliver is still Mayor, but Green Arrow is now Public Enemy Number One.
- "Blackmail" Is Such an Ugly Word: Thea brushes off her plans to blackmail a council member to swing the vote in Oliver's favor as "politics".
- The Bus Came Back: Alena aka Kojo Sledgehammer returns and welcomes Felicity to Helix.
- Character Development: The new team has lived up to Oliver's goals for them, culminating in his total acceptance of his life being in their hands. Well, except Evelyn.
- Composite Character: In the DCU, Prometheus and Adrian Chase are two separate characters, the latter being the civilian identity of Vigilante.
- Decomposite Character: In the comics, Vigilante and Adrian Chase are one and the same. Here, they are two separate characters.
- Evil vs. Evil: Vigilante tries to kill Oliver which naturally puts him on Prometheus' list. Prometheus probably would've won their fight had it not been for Vigilante's uncanny ability to pull a Stealth Hi/Bye.
- Fair-Play Villain: During the flashbacks, Viktor opts to agree to Anatoly's request of electing a new Pakhan instead of finishing Anatoly and Oliver even though they have them at their mercy. Gregor on the other hand opens fire once he loses the vote.
- Good All Along: While many viewers saw Susan as a Bitch in Sheep's Clothing, this episode reveals that she really does care about Oliver and she even keeps his secret.
- Heel Realization: Thea resigns as Oliver's chief of staff when she realizes she's becoming too ruthless and leaves to "fix" herself.
- Hope Spot: Curtis thinks Paul is meeting him for dinner in order to give him a second chance. In fact, he's handing him divorce papers.
- I Did What I Had to Do: Thea tries to justify her shady actions at first, until she has a Heel Realization.
- Insistent Terminology: Curtis is pretty annoyed at everyone calling his T-Spheres balls.
- Must Make Amends: Oliver strong-arms Thea and Felicity into making amends with Susan so she can get her job back.
- Not His Sled: In the comics, Adrian Chase and Vigilante are one and the same. Here, Vigilante is someone else, and Adrian is actually Prometheus.
- Pragmatic Hero: Thea plans to blackmail a councilor in order to help Ollie win the hearing and even proposes framing Billy posthumously. Oliver is not amused.
- Pre-Asskicking One-Liner: After Vigilante mocks Curtis for missing after tossing a T-Sphere at him:Curtis: They aim themselves.Sphere flies in and explodes in Vigilante's face
- Properly Paranoid: Vigilante correctly anticipates that Green Arrow or his team might figure out he's planning to assassinate Oliver Queen during the laters speech from a building across the city hall, and thus set up sensors to warn him if someone else enters the building.
- Pyrrhic Victory: Oliver as the mayor is acquitted, but as the Green Arrow he is now public enemy number one.
- Recycled Set: Curtis meets Paul in a nice little restaurant... that is clearly the Jitters set from 'The Flash (2014)''.
- Red Herring: Adrian's strict anti-crime views (plus the fact that they're the same person in the comics) were meant to make us think he was Vigilante. In fact, he's actually Prometheus.
- The Reveal: Adrian Chase is Prometheus.
- Running Gag: Curtis's T-Spheres being called "balls" by other characters.
- Shout-Out: Vigilante has already been compared to The Punisher. And his first line in this episode? "Bang."
- Taking the Heat: Adrian offers to take all the blame at the start of the episode. In the end, Oliver decides to frame his own second identity.
- That Came Out Wrong: When Curtis presents his T-Spheres, Rene summarizes it as Curtis getting balls to improve on his combat skill, before he recognizes that was taking it too far.
- Title Drop: Oddly it came from John in regards to Felicity using the Pandora files to blackmail others.John: "Sometimes we do fight fire with fire, but every single time we risk being burned."
- Took a Level in Badass: With his new T-Spheres, Curtis forces Vigilante to flee, after he already wounded Rene and John.
- The Unfettered: Oliver throws Green Arrow under the bus to keep himself from getting impeached.
- The Un-Reveal: We still don't know who Vigilante is, and since he escaped again, we may not find out any time soon.
- Villain: Exit, Stage Left: Vigilante, yet again.
- Wham Shot: Prometheus unmasks himself to reveal he's Adrian.
- What the Hell, Hero?: On top of still being mad at her for ruining Susan's life last week, Oliver is angry to find out that Thea now intends blackmail a council member to swing the vote in Oliver's favor.
- John calls out Felicity on everything she's been doing with Helix's illegally-collected data.
- Xanatos Gambit: No matter what Oliver does to combat the impeachment proceedings, Prometheus wins. Sensible, given his only goal is to destroy Oliver emotionally before killing him.
- If he gets impeached, he's removed from office and Star City is destabilized once again, undermining Oliver's confidence.
- If he doesn't get impeached, but condones blackmail to combat it, then he's compromised his morals.
- If he doesn't get impeached, but uses someone as a scapegoat (the candidates offered being Adrian or the deceased officer Malone) to save himself, then it further pushes the point that Oliver's choices wind up hurting his friends and family.
- If doesn't get impeached, but tosses his alter ego under the bus (which is what he does), then Green Arrow is Public Enemy Number One (again) and that restricts his ability to operate as a vigilante.
- The only wild card was Vigilante, which if he succeeded in assassinating Oliver, Prometheus' revenge plot would have been undermined, but it still would have been a devastating loss for Team Arrow.
