Tropes:
- Actually Pretty Funny: Why the Joker went along with the lie of Duela being his daughter; he just found it hilarious.
- The Big Damn Kiss: After a lot of Belligerent Sexual Tension, Steph and Harper share a kiss at the end of this episode, which at last confirms Steph's a lesbian.
- Clark Kenting: At the Ace of Clubs, Turner lampshades that wearing a beanie hat makes him unrecognizable.
- Closet Key: Stephanie realizes she's a lesbian by growing attracted to Harper.
- Coming-Out Story: Stephanie reveals herself as attracted to women, at least to her romantic interest, Harper.
- Corrupt Cop: Lincoln waltzing into the interrogation room while the Commissioner is "on her lunch break" has Stephanie realizing she's in the Court's pocket.
- Dance of Romance: Stephanie and Harper dancing sexily together at the club (just for cover at the time, it appears), came shortly before the former kissed the latter, after she realized her attraction to girls.
- Deceptive Legacy: Duela's mother Jane Doe had lied to her from the beginning that the Joker was her father (with the Joker's approval); it turns out that Harvey Dent is her real father.
- "Eureka!" Moment: It's when Jane complains Harvey was acting "like two different men" that Harvey finally realizes his alternate personality was already taking him over back then.
- Gaslighting: Jane Doe accuses Harvey Dent of doing this to her, saying he would have sex with her secretly but then claim they had no relationship in public, before finally having her locked in Arkham as a supposedly dangerous, deluded stalker. After he hears this, Harvey realizes that it was his alternate personality who had been with her. Doing things such as leaving a cow's heart as a "gift" with his secretary probably didn't help her case however.
- In Name Only: So far, at least, Jane Doe is an extremely far cry from her comic-book counterpart, a completely skinless woman whose M.O. is to Kill and Replace other people by removing her victims' skin and hair and wearing it over her own body while perfectly mimicking their voices. Here, she's an ordinary woman (if a bit mentally unhinged) and criminal without any special abilities like this. In a previous episode, Duela mentioned that her mother had taken on many different identities as a con artist, but she's not shown doing so here and presumably only used mundane disguises when she did.
- Internal Reveal: Cullen finds out that Carrie tore the pages out of Bruce Wayne's journal.
- Lipstick Lesbian: Stephanie forced herself to date boys just to please her parents and conform, but is in reality a lesbian, with a very feminine style (long hair, usually dressed in a blouse and skirt), confessing her feelings for Harper (a bisexual girl).
- Making Love in All the Wrong Places: The episode confirms Duela and Turner had sex in the library, as they're shown lying there together afterward. She then dishes to Harper on this, with far more details than she'd like later.
- Mythology Gag:
- The original character of Duela variously claimed the Joker and Harvey Dent as her father. She only says the Joker here but then it turns out Harvey Dent is her actual father.
- Jane complains Harvey was nothing but a "two-faced liar."
- While dancing at the Ace of Clubs, Stephanie says that Harper should have a codename like Robin and suggests Bluebird based on her blue hair streaks, which is Harper's superhero name in the comics.
- Harper asks Stephanie, "Ready to spoil the party?", alluding to Steph's own superhero name in the comics, Spoiler.
- Not Me This Time: Lincoln claims to have nothing to do with Arthur being arrested (he loves his show) but is happy at the convenient timing of it.
- An Offer You Can't Refuse: Lincoln thinks he has one when Stephanie's father gets arrested for illegal possession of prescription drugs (to give her addict mother), saying he will get the charges dropped if she gives up the fugitives. Stephanie however realizes this would mean her friends dying. After agonizing briefly over it, Stephanie refuses the offer, realizing she can't save her parents from themselves anyway.
- Parental Sexuality Squick: Duela repeatedly comments "Ew" when her mom mentions her sex life.
- Patricide: Duela has carried a bullet she wants to kill her father the Joker with for years it turns out. When she learns her father is really Harvey Dent, Duela shoots him at her mother's urging. However, he lives due to a Court of Owls coin which was in his front pocket stopping the bullet.
- Pretty Boy: When Turner doesn't want to abandon their friends to run away from Gotham with Duela, she scoffs that he's too pretty for a life on the run anyway.
- Psychological Projection: Harper accuses Crystal of projecting all of her own negative personality traits like selfishness onto Stephanie.
- Queer Colors: The episode features several scenes of Stephanie and Harper being bathed in blue and purple light, which both symbolizes their respective Color Motifs from the comics (Steph is Purple, while Harper is Blue) and foreshadows Stephanie realizing that she is gay and in love with Harper. Significantly, they're the colors of the bisexual pride flag (Harper's bi).
- Relationship Upgrade: Harper and Stephanie embrace their mutual attraction and become a couple via a Big Damn Kiss.
- The Reveal: Duela's birth father is not the Joker, but Harvey Dent.
- Sexy Discretion Shot: Turner and Duela had sex offscreen in "Poison Pill" (several times, it turns out) with them shown lying together afterward here.
- Too Much Information: In contrast with the conversation it's intercut with where Turner refuses to give Cullen any details on what he and Duela have been doing, Duela tells Harper gleefully of having sex with Turner ("riding the Bat-wang" as she puts it) several times in the library, including where Harper's preferred books are, to her increasing horror. Harper ends up covering her ears over this. Cullen is less than pleased at hearing about it later too, to a lesser extent, and Carrie jokes that she'll never banish the mental image of them having sex when Cullen tells her.
- Wham Line:Jane: Duela, meet your father...Harvey Dent!
