From an early version of the script:

Mae: "What kind of world is it where a man has to shovel coal all night for 60 cents but can get his face beat in for 70 dollars?"

Jim: Think of all the people who'd give anything for 70 bucks.
(Anger overtakes her without warning)

Mae: I've never told you not to fight!

Jim: (Softly) Easy

Mae: (Trying to calm down) You're not even healed up yet.

Jim: Got to take 'em when they come. It's not like the old days. People don't have the money to buy tickets anymore.

He hesitates then takes her hand. Instead of lacing her fingers through his, she holds his hand tenderly in her lap.

Mae: It's broken, isn't it?

Jim: Chipped a bone. Doesn't hurt.

She lifts his knarled and stained hand gently and kisses it.

Mae: (whispering) Liar!
