Here is how Hiro's back goes in Luna and Yuna.
Hiro: Luna, I'm home.
Princess Luna: Hello, Hiro, How'd it go?
Baby Yuna: (happy gurgling)
Hiro: It wasn't too long. I took some time explaining the example of differences between Sodor and Equestria.
Princess Luna: I can't imagine why.
Baby Yuna: (embraces her mother)
Princess Luna: Oh, Yuna! (picks up Yuna) You know how much we love you. (kissed Yuna)
Baby Yuna: (laughs)
