(Micah leaves, slamming the door, and Mark tries to follow)
Lucas: You can't help him with this, son, he's gotta do it by himself. Now sit down and finish your dinner. (Mark is upset, thinking Lucas is being mean) Micah used to be a peace officer, son, one of the best. Then, well, he got hurt and he... went all the way to the bottom and now he's a-he's afraid. He's afraid to carry a gun... afraid to pin on a star - so he drinks too much.
Mark: Whiskey, ya mean?
Mark: I know just how he feels. (Lucas is surprised) I took a big swallow once, Arch Quinn dared me. Guess I felt sick for an hour afterwards.
Lucas: Well, I'll bet that taught ya a lesson.
Mark: Taught Arch, too. He got sick just watchin' me. (Micah reenters, slamming the door)
Micah: McCain! I'm useless here.
Mark: Whiskey make ya work better...? Supper will. (Micah smiles and sits down to eat)
