You have some good points, Sonja and butler. Especially about Mrs. Twist looking scared. I welcome your thoughts.
That Ang Lee is maddening sometimes with the way he presents things so ambiguously. Even the visual of Peter McRobbie as Old Man Twist was puzzling. The way he stared at Ennis with his two differently colored eyes. I've heard that there are myths about people with different colored eyes, that they are oracles or witches, or just see things differently. The way he chewed his tobacco and spit it into a cup. He seemed to me to be the Old Man who, in movies and stories, acts as kind of an oracle and sums the story up. There was such a character in McCarthy's No Country for Old Men, who was also blind.
Then, when Ennis comes down the stairs with the two shirts, he actually turns to Twist and presents the shirts, showing the old man that he has them. Or one of them, anyway. The bloodstained shirt of Ennis's is hidden within Jack's denim shirt. Twist doesn't seem to react at all, but Mrs. Twist reaches for a paper bag (like the one Ennis began his journey with) to put them in.
