It is the sigh before she starts the story that you understand.. she’s told this story many times before. It’s rehearsed. She knew he was murdered.

She only realised when he told her they used to herd sheep in the mountain back in 63, then everything clicked for her, that's the scene...

The shirts…heartbreaking. 💔

all we have IS BROKEBACK MOUNTAIN!!

This scene is brilliant because there are several scenarios, all possible, in which Jack could have died.

Well I thought if she knew she would have divorced him like the other wife did but she seemed not overly perceptive either of her husband not getting along with her Father other tensions and didn't sit at home counting the minutes till he got home either like the other wife did I thought she believed it was just his fishing buddy not his lover or likely would be more hostile toward him. His parents his Mother I think knew more than her the way she gave him the shirt told him he was welcome back etc.
