That post-divorce scene is really moving, and just highlights the fear and repressed emotions Ennis has about his feelings for Jack. On first showing, I didn't even get the significance of the white truck - in fact, I first thought it was Alma for some reason - but on second showing, I realised it was noone, but just the fact that someone, anyone could see him standing talking to Jack, would make them suspicious, in Ennis's mind. Jack was totally oblivious, in his own world of thinking how life would be now that Ennis was divorced...only to be brought back down to earth with devastating effect. Heath Ledger was heartbreaking here I feel, he could hardly look Jack in the eye, but when he did, he was trying to say so much in those few words ("I'm sorry Jack, you know I am"). Poor Ennis.....poor Jack...... :'( :'( :'( :'(
