After a year-long stint in Arkham, Harley considers going solo.
Tropes:
- Asshole Victim: The boat party Harley and Joker crash at the beginning of the episode is literally celebrated by a bunch of old white guys giving a toast to a pile of money they got from "fucking the poor."
- Balls of Steel: With a metallic "clang", when Harley delivers a kick-to-the-crotch on a Brawn Hilda Arkham guard.
- Batman Gambit: Poison Ivy, of all people, pulls this off when it's revealed that Riddler's scheming in the episode is actually her doing in order to convince Harley that Joker never loved her. Of course, she would expect him to choose Batman over Harley in a Sadistic Choice.
- Batter Up!: Harley decides to use her signature baseball bat in her fight against the Joker's goons.
- Bring It: Harley's response to Joker siccing a room full of goons on her.
- Brown Note: Riddler claims to have a riddle that will make heads explode, but it turns out to be a lie.
- Can't Kill You, Still Need You: After destroying his hideout, Harley spares Joker so that she can see the look on his face when she becomes the queenpin of Gotham City.
- Epic Fail: Somehow, Calendar Man can't remember the date of his own son's birthday, despite knowing the exact length of time the "porn clown" (as his wife puts it) has spent in Arkham. All he can figure is that it's "Juneish".
- Establishing Series Moment: The moment Harley starts speaking, she starts dropping a ton of swears, showing that this is definitely not a kid's show by any stretch of the imagination.
- Everyone Has Standards: Nearly everyone agrees that Joker is a terrible boyfriend and question why Harley would bother waiting for him in Arkham despite it being very clear that he isn't interested in rescuing her.
- Evil Is One Big, Happy Family: At least the ones in Arkham are, as they all are trying to get Harley to dump the Joker for her own good. The Riddler even volunteers in Poison Ivy's Batman Gambit to help her realize this.
- Evil Versus Evil: There are plenty of instances of villains killing other villains here, but the most prominent one is Harley Quinn turning on Joker, fed up with his abusive boyfriend ways.
- Eye Cam: Harley waking up after the prison breakout is framed by her eyelids. The first thing she sees are Poison Ivy's plants.
- Idiot Ball:
- Harley for expecting Joker to spring her out of Arkham even after many months to even one year passes since she was committed there. But then again, she was super-infatuated to him at the time.
- Though it's used as the basis for hilarious cruelty, Calendar Man's son is somehow able to get a cactus to the visitation room, which the guards then burn and scold him for.
- Why did Arkham even allow oranges to be served to the prisoners anyway? Or not buy seedless ones?
- Instantly Proven Wrong: Harley fends off Riddler's insistence that Joker will never come to spring her out of Arkham, with Harley stating only the Riddler thinks that, before all the other prisoners and even the guards shout in unison "HE'S NOT COMING!!"
- Ironic Echo: When Joker tells her that he can call off his men from attacking her if she admits defeat, Harley responds the words he said in the flashback: "Til death do us part".
- Mythology Gag:
- When the Joker finds out via the news that the Riddler is more famous than he is, he shoots his television.
- The Riddler kidnaps Batman and Harley Quinn, then makes Joker choose who gets dropped to their death.
- The Joker stabs one of his henchmen with a billiard cue while saying he's agent of chaos.
- Harley takes to using a baseball bat during a brawl with Joker's henchmen.
- No Honor Among Thieves: Joker abandons Harley to fight Batman on her own (just so he can have time to escape) and doesn't even bother springing her out of Arkham.
- Properly Paranoid: The Arkham guards use a flamethrower to incinerate the cactus that Calendar Man’s son brought out of fear that Poison Ivy can use it. Considering that a single orange seed shat out by Riddler is enough for her to execute a prison break, they were right to be afraid.
- The Reveal: After Ivy saves Harley from the acid that is actually margarita mix, Ivy reveals that she set the whole thing up to prove that Joker doesn't care for her.
- Sadistic Choice: Riddler suspends Batman and Harley over pits of acid and makes Joker choose which gets to live. Joker picks Batman because he doesn't want Riddler to have the credit for killing Batman.
- Self-Serving Memory: Harley believed that she danced with Joker at the wedding and him telling her "til death do us part". In reality, she never danced, they were on a rooftop committing a crime, and he said the words to Batman, not her, as he left her with a live grenade as a distraction.
- Significant Wardrobe Shift: Harley's first costume (her traditional harlequin one) shows the symbolism of being made into a fool to believe that Joker loves her when in fact, he does not. Her second costume symbolizes the fact that she is going to leave him for good.
- Shoot the Television: Joker rids his TV with bullets after the news call Riddler the "funniest Gotham villain".
- Take That!: After Harley mentions she got a Reese Witherspoon movie for date night, Joker states a desire for it to be Legally Blonde.Harley: [nervous] It's Sweet Home Alabama.
Joker: This. Day. SUUUUUUUUUCKS! - Time Skip: Takes several times during Harley's year-long stay in Arkham, punctuated by Harley insisting that Joker will break her out, despite everyone there telling her, "He's not coming!"
- Title Drop: The title comes from Harley's delusions on Joker proposing to marry her "til death do us part".
- Toilet Humour: Ivy's prison break is made possible by Riddler eating an orange during mealtime and shitting out a seed for Ivy to work her Green Thumb on, when the guards usually take steps to keep plant life out of her vicinity.
- Unwanted Rescue: Harley is insistent that Joker will rescue her, even as an increasing length of time demonstrates the opposite. Ivy finally loses her patience, arranges her own breakout, and knocks Harley out when she won't escape willingly.
