This wasn't in the manga.
Why is anime Jotaro such an asshole towards his own grandfather?

LOOK, NO ONER EVER SAID JOTARO KUJO WAS A GOOD GUY.
Do you remember how he treated Joseph when they first met in in prison? Something like this isn't out of the question for him at all.

At least when he was in prison Joseph tried to get him out against his will and even then he apologized for having him come all the way from America.
He's just being a dick for no reason here.

Joseph is scared like a baby. Jotaro doesn't like babies.
Jotaro is a dick, didn't you get the message?
