- Mary Ingalls Kendall: [the tragic moment, when Mary Ingalls awakens to discover she has lost her sight] Help me, Pa! HELP ME! Pa, I can't SEE! Hold me! It's dark! I'm scared, Pa! Hold me! It's too dark! I can't breathe!
- Charles Ingalls: I wanted to talk to you. See, your Mother and I have been hoping and... praying, but it was the scarlet fever and it weakened the nerves in your eyes.
- Mary Ingalls Kendall: It'll get better, won't it, Pa? My eyes will be alright again.
- Charles Ingalls: The doctor thinks that it'll get worse
- Mary Ingalls Kendall: Pa?
- Charles Ingalls: He uh... He feels that... your gradually going to lose your sight.
- Mary Ingalls Kendall: Blind? I'm gonna be... blind?
- Charles Ingalls: I pray and I pray. Why doesn't God listen?
- Reverend Robert Alden: He listens, Charles. And He always answers our prayers. He doesn't always answer in the way that we want, but he always answers in a way that He thinks is best for each of us.
- Charles Ingalls: How can taking the sight from a fifteen year old girl be the best thing?
- Reverend Robert Alden: We're only finite. He's infinite in His wisdom. I can only tell you that there is a reason. Charles, believe me. God must have chosen Mary for some very special purpose.
- Charles Ingalls: Tomorrow I have to tell my daughter that she's going blind. What should I tell her is that special purpose?
- Seth Barton: I really like your family.
- Mary Ingalls Kendall: They like you, Seth.
- Seth Barton: I don't think Laura likes me.
- Mary Ingalls Kendall: I think she likes you a little too much.
- Seth Barton: Oh.
