[He doesn't bother with Josuke's inquiry and keeps himself silent by taking a long sip of the coffee. What it boils down to is that he's too old and too miserable to also spend time hating Josuke. That takes too much out of you and isn't conducive to a quiet peaceful life. Would he have liked to kill the boy and wash his hands of this mess? Absolutely.

But... The Fourth God made him a promise. A wonderful promise. He can put his hate aside for all of them. Because when the Fourth God wins... Oh, it's going to be so wonderful! So this. All this nasty time and energy consuming hatred... it is so pointless and unnecessary when he's unknowingly won. (Assuming the Fourth God actually beats the Fog Witch, that is.)]

It's mother? Hard to say. Princess of the Universe or God Save the Queen. That's a ragdoll and a persian. Big fluffy cats. The father could be any of the boys so your cat could become anything. Long haired, short haired... I don't know why it has a mouth like that but it's your chatterbox now.

That one in particular likes to climb. Climb specifically up your leg and then scream for food.

[The first time that happened he knew exactly who should get this furry annoyance even if he was still cold on giving Josuke a cat.]
