Nellie: How can I eat knowing that Laura Ingalls is going to ride my horse in the race?
Nels: It's not your horse anymore.
Nellie: You shouldn't have given it back to her. You should have shot it.
Nels: Now look here, young lady. I wouldn't bring that up again if I were you! You mistreated that horse, and furthermore, you lied to us about being hurt. You don't deserve a horse, and that's final.
Harriet: Well, I never thought I'd see the day when you would take sides over your own flesh and blood!
Nels: A fact is a fact. She'll get over it. In the meantime, she doesn't deserve a horse.
