Lucas McCain:
It's over and done with now Mark. Why so glum?

Mark McCain:
If they'd have hung you pa, it would have been all my fault.

Lucas McCain:
Now wait a minute son. Don't you ever think that way. If they'd have hung me it would have been Charlie Crown's fault. Nobody else's.

Mark McCain:
Charlie Crown. Stealing his own pa's horses and then selling them to poor Mr. Schneider. Just to get money. Guess I didn't make such a good trade after all. Guess I better leave the business to you.

Lucas McCain:
No siree! We're partners. Every lesson you learn makes you a better partner. Only one thing...

Mark McCain:
What's that?

Lucas McCain:
Just remember the lessons... Both laugh.
