Who's the Mommy here anyway?

(upon Hannah coming out of her room after bedtime)

Me: Hannah! Get back in bed right now!!!! (yelling voice)
H: (runs back to her room sobbing)
L: (to H) what's the matter sweetie?
H: mommy yelled at me! (sob sob)
L: (comes out to find me and says in a very stern voice:) Mommy! Did you yell at H?! You say you're sorry right now! (returns to bedroom)
L: (to H) mommy is going to say "you're sorry", ok sweetheart?
