Helena Kyle: Do you have any idea how hard it is to find clothes that look sexy?
Helena Kyle: I like to look at the law as sort of a guideline, kind of a helpful suggestion.
Helena Kyle: [to Dinah] News Flash, it's high school. The closest thing our society has to institutionalized torture.
Alfred: [to Barbara] Batgirl was strong but impetuous. You've grown into a thoughtful, beautiful woman with the capacity to care more for others than you do for yourself. And if that's not a hero, I don't know what is.
Alfred: A good butler does not eavesdrop... he discreetly overhears.
Helena Kyle: [about Reese] He's not my boyfriend. Boyfriends share things with girlfriends. They don't hide massive secrets!
Barbara Gordon: Just because something looks simple doesn't mean it is... and nothing worth having in this life is easy.
Helena Kyle: Oh, no... you do NOT mess with the outfit!
Harley Quinn: That's my boy!
Barbara Gordon: We thought we could do no wrong. We ruled Gotham's nights and answered to no one but ourselves.
Alfred: If I may be so blunt, Miss Barbara... this mask... this suit... no longer fits.
Helena Kyle: The drinking came after the driving... and armed robbery... but before the dancing and strip poker.
Harley Quinn: I mean, really, he is the perfect child for the busy career woman: Low maintenance. No sleep deprivation. They don't live long enough to borrow the car.
Helena Kyle: This whole thing is gonna send me straight to my shrink.
Harley Quinn: Me and my Mr. J, we would have had such beautiful children - my green eyes and his green hair.
Harleen: The city is gonna pay for what they did to my sweet Mr. J.
Helena Kyle: [about Dinah] She's dangerous when she's pissed, huh?
Barbara Gordon: Dealing with demons is never easy, whether they're on the outside or the inside.
Helena Kyle: Our jobs are supposed to be so easy: Find the bad guys, kick the crap out of 'em, feel good, and go home.
