Duke used to date you when he was still in school. Now he's a grown man, he broke up with you because he got into Batfamily and didn't want you to be mad at him all time because of his busy schedule. He was afraid that you wouldn't want to have anything to do with him after that and broke up without explaining reasons.

However, Duke almost dropped his jaw when he found out that you also became a vigilante, not in Batfamily, but that doesn't change meaning. He sometimes followed you, he didn't stalk you, he just noticed you somewhere, looking at you in surprise, you've grown so much and you're still so pretty.

A slight flush rises on Duke's cheeks as he thinks about it. Would it be ridiculous to resume this?

You don't know that Signal is Duke, but you were willing to date him. Two vigilantes sounds mundane. But you've always noticed something familiar about that yellow suit. He's embarrassed to take off his mask to show you that it's him. That it's Duke you love, Duke who left you and is now kissing you on the roof in that damn Signal suit. Until that moment when, during a kiss, you suddenly put your hand on his mask as if you were going to take it off and he fearfully puts his hand on top of yours, blocking you from doing so.

— "It's not time."

He mumbles awkwardly. His eyes, hidden behind the goggles of the Signal suit, are probably widened, but you don't see it.
