A Crusader asks about Joseph's hand and with no hesitation he says "I had a Karz accident."
Jotaro just has this weary expression while everyone else is baffled because of course his grandpa told him this all about story in the past ( Okay, sure Vampire and Stands are proven to be real supernatural things but CMON OLD MAN!!! the Ultimate Being??? Bullshit. ) and he refuse to believe that could possibly, in any conceivable way, be real.
And then, years down the line, Karz returns to earth and Jotaro is just. Oh No.
I am not proud to say that first line got an audible snort out of me but I'm also not too much of a coward to admit it
that is. 100% absolutely a thing Joseph would say and he's super evasive about the specifics of the accident, not in a Traumatised way but in a Lets See How Long I Can Not Explain This way
Jotaro is Too Fucking Tired to deal with jiji's bullshit and he isn't sure is he's pleasantly surprised or more exhausted at the fact his story was true
he settles on More Exhausted
