huge fan of the headcanon that Duke can just... turn invisible and no one except for the BatFam/certain Associates know/can avoid him
Like Bruce is leading Clark and Diana through the Manor and chatting and randomly walks around the middle of the hallway for no reason and Diana follows him while Clark just walks headfirst into Duke and neither Duke nor Bruce realized what they'd done
Tim is casually talking with a couple of friends he has over and randomly picks up a sandwich from the plate in the middle of the table and holds it over his shoulder where it just disappears
Steph is helping Alfred set the table and just shoves a glass bowl into the abyss and lets go and Alfred is two seconds away from screaming when he realizes 'oh, Duke is holding it' and Steph didn't even realize he wasn't visible.
Hal is gesturing while telling a story on the Watchtower and turns to look at nothing and goes "You were there, tell them" and the emptiness starts talking and Barry nearly has a heart attack until Duke flickers into existence.
