Honestly, it's pretty funny when people just have a good time with it, like that episode of Frog>Prince where Rekki is having a tug of war with security guards over her sword in the lobby of a fashion show.
Typically Rekki will stand out like a sore thumb and probably be trying to take charge, breaking things or causing a scene, Subo will be desperately trying to just blend in, stay out of trouble and not cause a scene and Jules will probably be sat somewhere in a corner on their phone or quietly observing. Rekki is popular for cameos because she's very recognisable, but you can use anyone. Like on an upcoming page of Alien Heart, Urien and Zeph turn up on posters in the background
