David & Latjjoreme
More than that - the way she treated Ennis; the look of understanding AND joy (?) that he couldn't 'eat no cake right now,' the gentle hand on his shoulder @ that potentially devastating moment, the way she kept her sons room, her nudge of Ennis towards the room - she knew he didn't have a place to be with Jack's ashes, but he had his moment alone there in that room, the slight smile & nod of acknowledgement when he came down w/ the shirts, when she asked Ennis - the last link to her son - to come back and see them again.
Because of all that, I know that she, when Jack mentioned 'the Rancher' knew that that man meant little to nothing to her son. I absolutely believe that she just knew.
