have a bug au jazz ...flirtiing with? threatening? prowl.
prowl is against keeping the cybertronians hidden at first, so he and jazz bicker a lot. jazz wants to keep his friends safe, and prowl is worried that the cybertronians aren't as benevolent as they seem (the first one he ever saw was tarn- not helping this opinion at all)
he doesn't really warm up to the bugs like the other humans do, at least until jazz saves his ass from shockwave and he realizes he's been a jerk for no good reason.
jazz doesn't blame him, he didn't trust prowl either, he was just a hell of a lot better at hiding it.
(I had so much fun with jazz's expression -and then had to cover it up, so i'm including the scandalous visorless version lol)
