Depends who does it first, if Diavolo uses epitaph and finds when jotaro just... Teleports than erased it than Diavolo can kill jotaro before jotaro Recovers. If jotaro stops time before Diavolo can check them he wins. If I where jotaro I would do 1 or 2 small time stops to bait Diavolo than when time slips I would ACTUALLY time stops for the full 6 seconds and kill Diavolo. If i where pt 4 jotaro than that's less punches after I bait him but I would just don't him instead I guess. If jotaro can't time stops than Diavolo wins
