Little House on the Prairie, Season 4

Dr. Burke:
[to Charles about Mary] I didn't know your daughter had scarlet fever, Mr. Ingalls.

Charles:
Yeah, she had scarlet fever.

Dr. Burke:
How bad was it?

Charles:
It was bad. It was scarlet fever. What is it?

Dr. Burke:
The scarlet fever damaged the eye nerves. Weakened them.

Charles:
How long until she's better?

Dr. Burke:
I'm afraid she won't get better. The condition only worsens. Mr. Ingalls....Mary is going blind.

Charles:
There must be some mistake.

Dr. Burke:
I'm afraid not. I wish there was some medicine or treatment that would help, but there just isn't.

Charles:
There....some.....something. There must be something.

Dr. Burke:
It would have to be in the nature of a miracle, beyond the skill or knowledge of a doctor.
