See you then, JoJo.

Fufu, oh good. Caesar-kun really does understand Joseph after all.

Dio was later obliterated.

JoJoooooo! It's good that you lived, but you're an endless pile of trouble!! You haven't changed at all since we met in Venice!!

I think it's cute to think that Caesar-chan would be yammering on all the time about how worried is about Joseph, but he'd say "You dumbass...!" to Joseph if he came to heaven and would force himself to act all cool while kicking him out. (imagination)
