On the island, Fyers agrees to give Oliver and Slade a boat in exchange for the circuit board. To the exchange, Fyers brings his backup, Yao Fei, and Shado, who frees herself after Fyers threatens to kill her unless Oliver abides by the deal. A fight ensues, and Yao Fei is left behind. When Oliver, Slade, and Shado return to the hideout, the circuit board is gone; Fyers didn’t intend to hold up his end. Now the missiles are ready to launch, but Shado knows details of Fyers’ plan.As Oliver is literally hanging around in the base, he learns that John Nickel, a slumlord, is getting away with his crimes. The hood sneaks into Nickel’s home, but finds that someone kidnapped him. Over dinner, Diggle and Oliver discuss how Oliver is still “living on an island” after eight months. Everyone’s phone begins buzzing from a live feed of Nickel being interrogated and shot by “the Savior,” who is trying to clean up the Glades.Dinah and Quentin continue searching for Sarah, leading Laurel to track down the woman in the picture; it’s not Sarah. Dinah then reveals that she last saw Sarah before she went on the Queen's Gambit and was responsible for letting her go making her feel guilty for letting her daughter die. Still convinced Sarah is alive, she decides to leave Starling City but Laurel tells she can call her anytime. Moira meets with Frank Chen and assures him of Malcolm’s obliviousness to their part in his failed assassination. Malcolm later informs Moira that a Triad member was arrested and is willing to talk. As Moira tells Frank she ratted him out, the Dark archer murders Frank.Felicity tracks down the Savior, who now had ADA Gavin Carnahan hostage. Oliver follows Felicity’s directions, leaping tall buildings and sliding over car hoods, but comes up empty as the signal jumps around. Carnahan is killed. Thea visits Roy’s, but is knocked out as he is kidnapped. Diggle figures out that the Savior uses subway lines to move around. The Hood stops the Savior and saves Roy, who swipes a piece of the arrow. Oliver realizes that the circle glyph in his father’s book matches the subway lines near the Glades.
Tropes applying to this Episode:
- Action Girl: Shado. Double as Hidden Badass.Slade: ...well, that was unexpected.
- Borrowed Catchphrase: The Villain of the Week takes the Hood's catchphrase "You have failed this city!" before he brutally executes his victims on stream. Needless to say, Oliver isn't happy about this.
- Canon Foreigner: DC does have a character called "Savior", but he is completely different to Joseph Falk, being a superhero with powers. It's fairly safe to say Joseph Falk is an original character with no connections to this comic book version.
- Cassandra Truth: The guy who shows up at Roy's to deliver a handgun doesn't believe Thea's Thea.Guy: You look familiar... I seen you on tv or something?
Thea: Probably. I'm Thea Queen.
Guy: Yeah, right.
- Chekhov's Gun: An interesting case. Roy receives a literal gun for his upcoming robbery while Thea is visiting, but in an attempt to make her accept it, he unloads it (intending to only use it as a prop in said crime). His first reaction when the Saviour assaults him is to draw and fire his gun, but he never got around to reloading it.
- Crusading Widower: A villainous example. The Savior lets his wife's murder be his Start of Darkness and he never looked back.
- Evil Counterpart: To Oliver. The Savior is a vigilante trying to save his home, the Glades, by hunting down those he believes have wronged it... except he's less interested in saving and more in avenging, his victims aren't so clearly deserving, and rather than offering his targets a last chance to right their wrongs, he has them plead their case for their lives on live streaming video before invariably executing them anyway, since he's already decided they're guilty.
- Foreshadowing: After being rescued by the vigilante, Roy keeps the flechette used to save him. The lights in the club even turn red.
- Hypocrite: The Savior claims he goes after criminals, when he's a criminal; killing innocent people in cold blood and acting as judge, jury, and executioner.
- It's All My Fault: Dinah feels responsible for Sarah's death because she's the one who let her go on the Queen's Gambit with Oliver, which is why she is desperate to prove she's alive.
- Judge Jury Andexecutioner: The Savior feels fully justified in finding anyone he thinks of as guilty and murdering them.
- Knight Templar: The Savior really believes that he's just giving justice to wicked criminals as he kills teenagers and innocents.
- Mythology Gag:
- Dinah Lance leaves to go back to Central City and comments she'll be there “in a flash.” Central City is the home to The Flash in DC Comics, and in another coincidence, Dinah Lance, the Black Canary, first appeared in Flash Comics.
- Not So Different: They lampshade that Oliver is going after another vigilante.Oliver: I just don't like the idea that there's someone dangerous out there.Felicity: [significant look]Oliver: Someone else.
- Out, Damned Spot!: Moira sits in her car, weeping and scrubbing Chen's blood off her hands at the end.
- Parental Betrayal: Dinah reveals she knew Sara got on the Queen's Gambit with Oliver despite it being a betrayal of Laurel, and didn't tell Laurel about until now. Laurel is less than pleased.
- Pay Evil unto Evil: The Savior's intention. Except he considers a district attorney who chose not to take a case to trial for lack of evidence and a conflicted bit-part criminal barely out of his teens to be as worthy of public execution as a slumlord whose corruption has caused multiple deaths.
- Rapid-Fire Fisticuffs: Shado deals a round of these to Fyers, revealing her Action Girl status.
- Roaring Rampage of Revenge: The Savior's vigilantism comes across less as a calculated attempt to save the Glades and more as an extended version of this for his wife's murder; two of the three people he's seen targeting are the DA who chose not to prosecute his wife's murder and a young criminal he views as identical to the thugs who killed her, rather than more dangerous criminals.
- Snuff Film: The Savior's modus operandi is not only to execute whoever he sees fit, but to make sure everyone in the City gets a live feed of the victim begging with their last breaths.
- Vigilante Man: And unlike Oliver, the Savior really has lost it. He goes around executing people for petty reasons.
- Well-Intentioned Extremist: The Savior edges between this trope and Knight Templar. He really does desire to save the city, but is horribly misguided and takes it out on the wrong people more often than not.
