A few time ago I spoke with two other Brokies about the similarity of these two scenes-although they maybe could be included in the thread "Double meanings"...-.One of them says that in the first pic,Ennis turns his back to Alma,as if he didn't want to see her,maybe because he's believing that is Jack who is holding him.And that in the second,it's Ennis who is holding Jack,but he does it without wanting to see that is him whom is holding.She declared that all Ennis inner fight is seen in these two pics;that he never could be himself,neither with Jack,nor with Alma.
I said on my part that it also can mean that in the first pic is Ennis the held by Alma,the one who really loves.And that with Jack,he's the active part-I'm not talking about the sexual sense...

-,who holds Jack,who is the person he really loves too.Like a change of positions and feelings...What's your opinion about?.
