Bruce coming to Diana and other members of the JLA and every woman in his vigilante life to help when it comes to designing Steph's official costume as Robin because Steph is his first girl and he's not sure what to do.
Bruce: So the Robin costume is inappropriate?
Zatanna: You can't say that. But yes, she's a teenage girl and the early versions of that costume are seven ways of wrong.
Dinah: She's going to need better protection. Just because she's a girl and might want to look good, doesn't mean that she shouldn't think about safety.
Diana: And can't have her wearing shorts. It's freezing in Gotham.
Kara: Grayson was eight when he picked those, we will be polite and call them pants. Steph is a teenage girl.
Dinah, nodding: Yeah, shat if she gets her period? She's going to want as much coverage as possible.
Selina, holding his hand: Bruce, we discussed this. Every month-
Bruce: Every month? That goes on every month?
Selina: And she should get to have a say in all this, too. She's the one who wears it. And I'm sure she doesn't want to look like a carbon copy of the boys. She's a young girl, she will want to feel like one.
Bruce: We could... Um, give her a hairband? A red one? Red for Robin...?
Selina: that's... Ah, good start but we'll keep thinking.
