Nightwing and Robin in “Unfinished Business”

Nightwing

[brings one of the muggers to Robin] Here, kid. I think you lost this.

I coulda handled him.

Nightwing

Coulda, woulda, didn't.

You sound just like Batman.

Nightwing

I'm nothing like him.

Yeah, right. The mask, the attitude, the long underwear.

Nightwing

Drop it!

I'd love to know what happened between you two.

Nightwing

Things change.

No kidding. You guys used to be the greatest. Batman and Robin, the Dynamic Duo.

Nightwing

Maybe you should ask him.

I did. And you'll never guess what he said. "Things change".
