"The movie says this directly, without words; shows them strikingly unalike, right off.  Ennis has hitched a ride through the night in a big truck; he hops off, walks into Signal, shrinks, hands in his coat pockets, hides under his hat from the daylight, from other eyes, as he waits by Aguirre's office trailer steps.  A train passes -- through gaps between cars we glimpse him smoke a cigarette. The train recedes into the distance -- Jack barrels along the road towards us in his beaten up pickup.  It turns, skids to a halt with a couple of 
jolts, coughs, splutters, spurts of smoke.  Jack gets out, leans against it, hands on hips, open: the opposite of Ennis.
