Y’all know those fics where nightwing joins the justice league without anyone knowing about his connection to batman and stuff?
Well I need one where he joins the league and him and batman are able to act professional enough that no one even consider them knowing each other more than just as colleagues. They don’t seem particularly close, they work well together, which is to be expected considering how similar they are.
Literally everything is fine, no one has any doubts, it doesn’t cross anyone’s mind.
Then they walk in on them arguing.
At first it sounds like a classic argument that always happens when working on a team with someone. You’re bound to disagree on something at some point.
But then it starts to sound like the kind of argument that’s clearly a repeated thing. Whatever nightwing and batman are fighting about, they’ve faught about it before.
It starts sounding weirdly personnal. Too personnal for two coworkers who just started working together maybe a few months before.
It’s enough for the other members to start wondering if maybe the two might have known each other for longer than expected and have simply never mentionned it.
Then they hear it.
