Well, when one consistently refers to “my grandfather and grandmother,” like there’s only one of each (and presuming the other two aren’t dead), it’s kind of like declaring that fully half of one’s lineage is irrelevant. Kind of.

I’ve noticed that in a lot of fiction, when a character inherits some vital object or title — you know, a magic sword or the job of protecting the world from demons or something like that — it’s almost always inherited from the character’s father’s side, from the father’s father and from his father before him. In Marvel Comics, a lot of biographical information exists about the fathers of Mister Fantastic, the Invisible Woman and the Human Torch (they’re siblings), the Hulk, and others, but virtually nothing about their mothers.

I suspect that Joss Whedon deliberately subverted this in “Buffy the Vampire Slayer” when he revealed that it was Rupert Giles’s paternal GRANDMOTHER who had been a Watcher since her youth, and had then passed the role on to Giles’ father, who passed it on to Giles.

But whatever. ;-)

We’ve at least met Bruno’s maternal grandmother, who’s African-American:
