Diaz and Black Siren travel to Bludhaven to contact the Quadrant, the largest crime organization in the country.
- Barbaric Bully: Jesse, who abused a young Diaz in every way imaginable.
- Best Served Cold: After 25 years, Diaz finally takes revenge on his childhood bully Jesse.
- Bond Villain Stupidity: The Cartier crime family didn't check to see if Diaz was really dead. They should've shot him in the head.
- Boom, Headshot!: How Diaz disposes of Cartier Sr. after one too many taunts.
- Bullying a Dragon: No pun intended. Cartier Sr. really shouldn't have further taunted and insulted the man who just killed a dozen of his men, including his son.
- But for Me, It Was Tuesday: Jesse takes quite a while to remember Diaz. The latter is even disappointed he didn't leave more of a mark.
- Card-Carrying Villain: Diaz mentions that it feels good to finally be able to call himself a crime lord.
- Continuity Nod: Black Siren mentions how Diaz reminds her of her first employer Zoom, a man who let his hate consume him.
- Crazy-Prepared: Diaz anticipated that the Cartiers would double-cross him, so he wore a bullet-proof vest.
- Cruel and Unusual Death: Diaz douses Jesse with lighter fluid, before setting him on fire.
- Dark and Troubled Past: Diaz grew up in an orphanage with a sadistic bully as his roommate, having to fight for every scratch of food.
- A Day in the Limelight: This episode focuses on Diaz and Black Siren's efforts to gain favor with a crime family.
- Dirty Coward: Both Cartier Jr. and Jesse, when Diaz has them at his mercy.
- Disproportionate Retribution: Despite Jesse being a Barbaric Bully towards Diaz thirty-two years in the past, Diaz hunting him down and brutally murdering him by setting him on fire—after Jesse mentions that he has a family, no less—is portrayed in a very dark light.
- Even Evil Has Loved Ones: Possibly. It's mentioned that Diaz was abandoned by his father at an orphanage and kept his picture with him at his bedside before Jesse burned it. Diaz managed to salvage the last piece of the picture and kept it for years, before tossing it into the same fire he used to kill Jesse.
- Even Evil Has Standards: Black Siren is troubled by the gruesome and frankly sadistic way Diaz murders his former bully and tortures Cartier Jr. Earlier she seemed troubled when during Diaz's Motive Rant when she realizes he's basically another Zoom, minus the super-powers. Which is ironic, given how sadistic she has been shown to be earlier.
- Evil vs. Evil: The central conflict of the episode.
- Evil Is Petty: Diaz takes the trouble to hunt down his former childhood bully, to murder him.
- Freudian Excuse: It turns out Diaz grew up in an orphanage after his father presumably abandoned him. He had to put up with a sadistic bully who would often burn him and tells Diaz that he will never amount to anything. Diaz also mentions having nothing as a child and would often have to fight for every scrap of food he could get.
- Friendship Moment: Despite all that has happened, when push comes to shove Curtis is still Felicity's friend.
- Impaled with Extreme Prejudice: When they are storming the Quadrant's meeting, the shockwave of Black Siren's scream impales one of their opponents on a table leg.
- Informed Ability: The Quadrant, a group we've never heard of before, are made out to be the shadowy, nigh-untouchable kingpins in charge of all crime on the North American continent. Those few who have heard of the Quadrant consider them to be an urban legend. Nevertheless, Diaz somehow knows all about them, their internal structure, their relationships to one another, and the locations of all their Star City safehouses, and manages to completely out-play them at every turn. Diaz actually had to put more effort into infiltrating one town's already-corrupt police department than he does muscling his way into a supposedly all-powerful crime syndicate.
- Internal Reveal: Curtis finds out that Oliver is now the only member of his team.
- Karmic Death: Jesse, Diaz's childhood bully who burned Diaz's last surviving picture of his deceased father, gets burned to death. Diaz even throws the last part of the picture he managed to save into the fire.
- Klingon Promotion: How does Diaz get a seat at the Quadrant? By killing Cartier Sr.
- No Honor Among Thieves: The Cartier family had no intention of ever giving Diaz a seat on the Quadrant.
- Nothing Personal: Cartier Jr. tries to use this as an excuse for trying to kill Diaz. Black Siren is quick to call it out as bullshit.
- "Not So Different" Remark: Black Siren calls out the similarities between Diaz and Zoom, both growing up in orphanages and letting their hate consume them.
- Out-of-Genre Experience: By sidelining the heroes, this episode focuses on Diaz's efforts to ingratiate himself into a larger criminal syndicate; thus, the episode ditches the superhero genre and instead plays out like gangster fiction. This is also signified by the higher level of violence in this episode than usual.
- Self-Made Man: Diaz, who had to fight for everything he has today, as opposed to Cartier Jr., who had his daddy provide him for everything.
- Special Edition Title: Instead of an arrow symbol, we get Diaz's dragon tattoo in the background for the Villain Episode.
- Strapped to a Bomb: Cartier Jr.'s ultimate fate.
- Villain Episode: Almost the whole episode is dedicated to Diaz (and to an extent Laurel). Felicity and Curtis only have 2 scenes, while Oliver himself only appears in one.
- You Have Outlived Your Usefulness: After he rescued their man from the FBI, Cartier Jr. immediately tries to kill Diaz alongside said man. Luckily, he was wearing a bulletproof vest.
