So.....how come Jotaro's father never showed up in the manga?
He wasn't even given a face.
Same as Jotaro's wife
She was at least shown in some Jolyne flashbacks, but the reason they are not prominent is because neither of them are of the Joestar bloodline and thus are irreverent
Because Jotaro's father is a disgrace, he left Holly alone when the Stand started to kill her.
You shouldn't abandon your hot wife when she's struggling, you should make sweet love to her, god damn it.
>Your wife is being killed by her own spiritual power.
>You should fuck her.
