As Felicity and Oliver try to figure where they go next, Cupid returns to Star City killing off high-profile couples. Meanwhile, Laurel struggles to make a legal case stick against Damian Darhk.
- Amicable Exes: Subverted. Felicity and Oliver try to be this, but their feelings for each other make it all but impossible.
- Armor-Piercing Question: Quentin ask one to Darhk's attorney that completely silences him after testifying:"By saying all these things, I'm setting a match to my career. and maybe my life. So why would I be doing that if everything I'm saying isn't true?"
- Artistic License – Law: There's no way Laurel would be able to cross-examine her father (or Diggle, her friend) in real life—conflict of interests. Hell, the fact she was directly threatened by Darhk and is personal friends with some of his victims means she shouldn't even be presiding the case.
- Breaking the Fellowship: Felicity leaves Team Arrow, since she can't work with Oliver while he's still pining for her.
- Bulletproof Vest: Cupid shoots Oliver in the heart, but he's wearing a Kevlar vest under his tux.
- Continuity Nod:
- Cupid adopted the phrase "love is like a bullet to the brain" ever since she saw Deadshot die from the explosion in season 3.
- Also, her mentioning that the two men she has loved are both dead might serve as a reminder (if your attention has wandered) that in-universe the vigilante known as the Arrow and revealed to be Roy Harper died after being shanked in prison, and that this new Green Arrow is a different vigilante who has taken up his struggle.
- During Darhk lawyer's cross-examination of Diggle, he brings up the fact that he brought 80 kilos of cocaine on Thea's behalf. He also points out that Oliver lost his job as CEO of Queen Consolidated, meaning that he shouldn't have the money to pay Diggle to be his bodyguard.
- When Laurel is struggling with her case against Darhk, Captain Lance points out that there plenty of guests who saw Darhk attack Oliver's Christmas party. Laurel sadly informs them that she's been busy trying to subpoena them and most of them would rather take a Contempt of Court charge then testify against Darhk.
- Tatiana tries to smash the totem but can't. In the previous episode, it took Vixen several tries even with her magically-enhanced strength.
- Oliver stealing back all the money Adam Hunt swindled from his victims way back in the pilot is mentioned, as is his first encounter with Felicity in her cubicle.
- Conveniently Placed Sharp Thing: Oliver wraps Cupid with a bolo arrow, only for her to cut herself free with an arrowhead and escape the moment Oliver's back is turned. The second time she tries this, Oliver just tranqs her.
- Dark and Troubled Past: Reiter reveals that at a young age, his village was attacked by evil men who murdered everyone he loved. Oliver points out however that he is every bit as bad as they were.
- Double Meaning: During their fake wedding Felicity just gives a curt wedding vow like she wants to Get It Over With, but Oliver insists on giving his own vow spelling out in detail exactly why Felicity is special and promising never to lie to her again. She's entranced, and later when trying to talk Cupid out of blowing them all up, gives what is implied to be a version of her own vow while explaining her love for Oliver. Oliver naturally takes this as a hopeful sign.
- Dramatic Irony: Whenever Cupid pines over the dead Arrow when he's standing right in front of her.
- Dude, Not Funny!: Oliver responds with a Death Glare when Thea makes the usual Psycho Ex-Girlfriend quip, but points out with this one her brother missed out on all the fun bits. In fairness given recent events with Felicity he's really not in the mood.
- Eating the Eye Candy: Cupid appreciates the lack of sleeves in the Green Arrow's costume.
- Easily Forgiven: Averted Trope, it seems at the end Felicity might forgive Oliver and they will get back together, but she realizes there will always be times Oliver will feel it's necessary to keep secrets or work alone - and she's not okay with that.
- Fluffy the Terrible: According to his lawyer the man with the extremely on-the-nose and alliterative name is actually Kenneth Bender, an innocent citizen of Markovia.
- Foregone Conclusion:
- Although this episode does tease Oliver and Felicity rekindling their relationship, the lack of a ring on her finger in the most recent flash-forward is a good indicator that it's not likely to pan out anytime soon.
- The thing Reiter was after 5 years ago turns out to be a familiar-looking idol. It's fair to assume he'll lose it eventually.
- Giving Them the Strip: Oliver tries to grab Cupid only to find himself holding her gauntlet as she uses a grappling-hook arrow to escape. Felicity then cuts up the gauntlet and puts it into a gas chromatograph to find out where it was made, giving Team Arrow the location of Cupid's hideout.
- The Guards Must Be Crazy: The prison guards somehow missed that Darhk smuggled a ring inside his mouth.
- Heroic Sacrifice: Captain Lance testifies against Darhk, risking his career and liberty to do so.
- Hidden Depths: Turns out Thea is a big fan of celebrity gossip, including browsing message boards and blogger sites, and is apparently a Shipper.
- Honor Before Reason: The reason why Cupid's out of ARGUS's custody. Waller actually kept her word about the Suicide Squad members being able to work their way towards freedom.
- Hope Spot: At the wedding ceremony to flush out Cupid, it seems like Felicity and Oliver are ready to get back together. Oliver is, but Felicity's not.
- Human Sacrifice: Reiter orders his men topside to execute the prisoners so their lifeforce can power the totem. Taiana and Oliver overpower Reiter and run off with the totem, forcing him to cancel the execution.
- Improbable Aiming Skills: In her first dual homicide Cupid fires two arrows simultaneously, one into each heart of the victims who are sitting on either side of her.
- Jury and Witness Tampering: Heavily implied, as none of the guests who were at Ollie's Christmas party want to testify against Darhk.
- Monster of the Aesop: The Villain of the Week is obsessed with the death of romantic relationships just when Olicity has seen the death of their romantic relationship.
- Nice Job Breaking It, Hero: Oliver felt sorry for Cupid and had her sent to the Suicide Squad to do some good. Unfortunately this gives her the chance to work off her prison sentence and now she's back in Star City killing innocent people whereas before she was targeting criminals.
- Open Secret: As The Bait for Cupid, Olicity pretend to have a secret wedding which Thea leaks onto the celebrity blogs so everyone will know about it.
- Portmanteau Couple Name: In a nod to the fandom, the news refers to Oliver and Felicity's wedding as the "Olicity wedding". Leading up to this gag, Thea gives the In-Universe portmanteau names of the other celebrity victims, e.g. Allison Lee and Robert Joyce = "Allibert."
- Put Them All Out of My Misery: Cupid's new MO; kill high-profile couples to deal with the pain of losing Deadshot.
- Schmuck Bait: Two of Reiter's mercs find the totem sitting on the floor of the mine. As they're wondering why Oliver and Taiana left it behind, said persons jump them and take their guns.
- See You in Hell: AvertedCupid: I'd say enjoy the afterlife, but we both know that's just eternal nothingness.
- She Cleans Up Nicely: Oliver just stares in Stunned Silence when Felicity enters in her wedding dress.
- Shipper on Deck: Thea and Diggle do what they can to try and convince Oliver to patch things up with Felicity.
- Ship Sinking: It appears that Olicity is dead, for now at least.
- Shout-Out: On seeing Felicity cutting up the gauntlet, Thea dubs her Felicity Scissorhands.
- Silent Antagonist: Damien Darhk does not have a single line of dialogue in this episode, though his facial expressions say a lot.
- Special Edition Title: Like in "Broken Hearts", the arrow behind the title is one of Cupid's heart-shaped ones.
- Stealth Insult: Felicity's rather curt wedding vow.Felicity: Oliver, you have many qualities... many astonishing qualities. And I, for one, cannot wait to move on to the next chapter.
- Surprisingly Realistic Outcome: It is exceedingly difficult (if not impossible) for a vigilante team to testify in a court of law in their civilian identities and actually legally put someone away.
- Together in Death: At the episode's beginning, Cupid murders a couple with a double arrow shot, then poses their bodies in a heart shape.
- Trailers Always Lie: The original trailer for this episode that was released after the previous episode aired contained scenes that ultimately were not present (which included the characters of Curtis and Malcolm, both of whom were absent in this episode).
- Turn in Your Badge: Done without the usual Large Ham cop show drama as Lieutenant Pike accepts Captain Lance's gun and badge after his public confession that he was working for Darhk.
- Wham Shot: Darhk taking a ring implied to be imbued with magical properties out of his mouth, and then putting it on his finger.
- You're Insane!: Baron Reiter has just shot a man in cold blood so his lifeforce can power a magical totem.Oliver: Reiter, you're insane!Baron Reiter: The difference between insanity and belief lies only in the number of believers.
