- Catharsis Factor: Even with Adrian still at large, it's a huge relief that he's been revealed as Prometheus both to the authorities and the public masses on YouTube. Kiss that Villain with Good Publicity status goodbye.
- Moral Event Horizon: If Anatoly doesn't cross this by stealing diabetes medicine from a struggling company to make a street drug, he certainly does by holding hostages and trying to kill them to get Oliver to back down. Anatoly himself fully acknowledges this, saying this is exactly what he worried he would become without Oliver's influence.
- Nightmare Fuel: The ending, where Chase brutalizes one of his guards with a pen, clearly enjoying it. The last scene is him driving away into the night with blood on his face, whistling cheerfully to a song as the police drive by him.
- Separated-at-Birth Casting: If you've enjoyed Josh Segarra's Christian-Bale-as-Batman impression, you'll love his take on Patrick Bateman!
