nito was such an intimidating figure when they first met but now vash sees the big skelly-man as a big softie with a big heart somewhere in those old bones.
he'll always bring cookies or pastries when he visits--his brother and he are always experimenting with different flavors and fruits from their garden so id not be surprised if nito's become a taste-tester of sorts for them.

also seeing a pokemon as big as a giratina is definitely scary but vash totally knows what its like to be a big scary guy but actually be a shy fella
somehow giratina reminds him of nito himself

sometimes a parent is just like their pet huh
