Headcanon: Everyone just assumes that between Bruce and Hal that Bruce is the disciplinarian and Hal’s just there to look pretty. But one of these men was raised in a strict military family and the other one drove his butler wild with his rich kid shenanigans. So the JL are in for a shock when BruceHal are off-world on a mission and the Bat kids have somehow set 2/3 of the Gotham harbour on fire. Like the water’s on actual fire.
Barry: We’re going to tell Batman!
Batkids: *look at each other and shrug*
Batkids: Weird flex but okay.
Superman: And I guess we should tell Green Lantern as well?
Batkids:…disperse!
