No way.....it wasnt LaShawn, he was having it off with Randall.....
Remember he had told his daddy he would bring his friend up to the ranch, he was gonna leave his wife.......
Jack didnt need another woman....when he went to mexico, he wanted a man, when he played up, it was with a man.....
But, I do wonder why he even mentioned he was getting a bit on the side, from the ranchers wife.....was it so Ennis wouldnt think he was playing around with another guy, and to give him the picture of him still being a bit of a rascal, but with a woman....
