Pigeon Giovanni is his favorite aristocrat pigeon from a post-apocalyptic world.

No really, he's fond of him. He understands the pressure of having good ol' dad put a load of shit on you (and then have people get hacked off at you when you think you're doing a service for the family), and it was really the point where he stopped mocking Sakuya and started treating him like... well not a dumb animal.

Juan still does tack on a little "not bad for a bird" mentally whenever he talks about Sakuya, but that's because Juan's a classist, possibly kinda racist, and now apparently speciesist dick. Despite all of that he more or less treats him like a feathery human and he'd probably share things that he wouldn't with others... as long as it doesn't make him look like he's giving the family a bad name.
