Jack Twist: God, I wish I knew how to quit you!
Ennis Del Mar: Well, why don't you?
Ennis Del Mar: Bottom line is, we're around each other an' this thing, it grabs hold of us again at the wrong place, at the wrong time, and we're dead.
Jack Twist: That's more words than you've spoke in the past two weeks.
Ennis Del Mar: Hell, that's the most I've spoke in a year.
Answer: At first they were just wrestling and horsing around. However, underlying tensions and frustrations over their impossible situation, and Ennis' reluctance to commit to Jack, causes their anger (particularly Jack's) to overtake them, and it erupts into a full-blown fight.
