Sadly, that family photograph does not include my son, Hiro.

... I'm not your son or your Meister, Excalibur...

Fool! You are both. Do you know remember your mother, Arachne-Claire?

She was beautiful. You have your mother's eyes and wit, Hiro.

Um. I know my parents.

Then why aren't they ever in the show?

Because I'm a minor character and we haven't even met Maka's mom.

Hiro, I have something to confess.

You and Maka are related.

I am your father. Her mother is your mother.

... um. I really do know my parents. I grew up with them.

Those were robots.
