welcome to the shitshow :))

like so many dark edgy ya boys are brooding loners who aren't good with people but kaz is such a subversion of these traits

in the first scene we see him through inej's point of view he's cracking jokes with the dregs, he makes smalltalk about weather with the black tips, like Inej makes a point to note when he changes from being Kaz to being Dirty hands, who is all those edgy tropes but kaz isn't always Dirtyhands

"you're passable at demo you're excellent at hostage"

"why don't you pay someone to burn your Kruge for you thats what the big players do"

literally anything he says to Matthias when he's trying to goad him

like kaz is not some humorless sad boi, even his eternal monolog can be funny

"I definitely didnt tell them to blow up the lab"

"maybe I'm finally going to pay for all those tree spirit jokes"

also the entire scene with Van Eck when Van Ecks like "the best thief to send would be the guy who stole my deKapple" and Kaz just straight face saying "yeah. too bad we don't know who took it huh?" and then a scene later telling Inej to move it from its UNDER HIS BED cause he didn't even care enough to sell it
