I echo Tony, perarduaadastra. Great topic.
I also concur with Tony that it will be
work to detail the step by step development of the relationship. I don't know how much I can contribute, but I think it is certainly worthwhile, and as Tony said, surprising that it hasn't been done already.
I think Jack's nursing Ennis' wound was more than physical contact. The handshake, made obvious by Jack's waiting hand, as if to say to Ennis, I can wait forever if you are that damn shy, but I am determined to touch you. And that smartalec remark, "Your folks stopped at Ennis?" was meant to draw out more of the laconic cowboy. Jack showed interest from the first moment they laid eyes on each other and never let go. Handshake, beer talk, showing off at the jumping off point, etc.
Tending the wound was more revealing, showing a tender, softer side, without the bravado macho stuff. It's that gentler kinder Jack that Ennis fell for, and was willing to go hunt an elk. Ennis didn't want to shoot the sheep because he didn't want to get on the wrong side of Aguierre. But since he already made them break the law sleeping out there with the sheep, breaking another law is more acceptable of the two alternatives.
I agree that Ennis happy with beans while Jack won't settle for the same old boring food ration is a significant difference.
As for the comments about Ennis being the "shooter" and Jack's missing...

Interrrresting.

I also thought the comment about the coyote with balls the size of apples and the shower scene were unusual. Ennis appeared to be excited after the prospect of hunting down the coyote, his adrenalin pumping, his testosterone level up. I don't believe it was consciously a "come-on" but more like the macho machismo posturing that is common in the military among high-octane men. I think Ennis was just happy, in fact almost ecstatic just to be the "man" and not having to cook and tend the camp. It was like Ennis yearned to be the "man" in the relationship. There is no doubt Jack was attracted to that, as most gay men would be. I can't say if Ennis was consciously flirting with Jack, or simply appreciative of Jack's attention, acceptance, friendship, camaraderie. I suppose there is a fine line between preening and flirting.
Great topic!
