"There's lots of them, so they need nicknames," Kanim explains.

"We do know that if the same set of parents have children they will wind up with children who are alts of each other. Rose and Angela both married Jokers and had daughters, and Rose's girls match Angela's elder two."
"Oh, sweetie," sighs Glass, "not all alts are much alike, anyway, if they have one of you," she gestures at the visitors, "she'll grow up in such a different place. That other Tony is even a boy, there's no telling what another Carinna would be like."
"And she wouldn't be named Carinna. Not now that we know you had the name first. Although it's a very pretty name."
"I'm not sure. We haven't really talked about having little princesses."

Shell Bell kisses her cheek.
"But we might talk about it later," she tells Carinna.
"Will you let me name the me?" Carinna wants to know. "I think that would be fair!"
"I don't know yet!" Carinna says. "It might even be a boy. Then it would need a different name from if it was a me-me."
