Curate, connect, and discover
The Batkids definitely forget that their comms are on and linked up to each other's, which is what leads to instances such as:
Cass humming some song for our twenty minutes, nobody has even thought about interrupting and several Batkids have taken to texting each other
Bruce flirting with Clark
Barbara doing asmr as she works and hacks. It gets slightly more concerning when she starts talking to her dolls.
Sound effects related to devastating injury and then that Batkid furiously huffing and puffing and trying to play it cool (Dami, while everyone grimaces)
Bruce flirting with Selina
Dick bitching about something stupid a JLA member did and then going quiet, and threatening everyone listening in
Duke making sound effects under his breath and catchphrase-celebrating unseen feats of heroism and/or parkour
Steph making grim but cheerful comments about near misses while driving, and then going "Haha just kidding. Got you guys good."
Bruce flirting with Khoa
Jason panting heavily, and clearly running for his life, before profusely thanking a bus driver
Tim making mission impossible sounds very quietly as he walked after bad guys at the edge of some rafters. Followed by him falling through them
Bruce being awkwardly flirted at by Riddler, followed by an ew straight from someone's soul
Alfred's random commentary
