Little House on the Prairie, Season 9

Marvin:
[to Jenny] What are you gonna do now? Go home and feel sorry for yourself? That'll do you a lot of good.

Jenny:
You don't understand. You pretended to be my friend, but you don't care. You don't care at all!

Marvin:
That's it! That's it! Get angry! It's good for you! I do it lots of times, because I'm a doctor and I'm going blind. And that makes me damn angry because I'm still a good doctor and I can't help people anymore! [voice softens] I do understand, and I do care. If I didn't care, I wouldn't have told you to go back to school. I didn't want you to, you know. I wanted you to spend your days here with me. I couldn't wait for you to come every morning. It made me feel that I was still able to help someone, that I was useful. And I wasn't quite so frightened with the coming doctors, because you were around. Jenny, you're my last patient, and you're getting better. You're getting better all the time and you can still keep getting better as long as you fight. You got angry today. Use it! Fight this thing. Show Nancy. Show them all!
