I did used my lunch wisely and pulled my copy of closed range and my laptop and my copy of the BBM DVD and went to a part of the cafeteria and watched that scene and reread the that part. And well on my personal thought Jack was on his ending, i mean he was at the border of desperation for almost 20 he had being working hard to get Ennis with him and to make a life but he is always unable to get that. he hides his desperation to Ennis and always shows him his happiness and like a glass of water, his anger, bitterness, and all he the feelings he have are getting bigger and bigger. He love Ennis and he hates him, he love him, he always did and will do, but he also hates him because thanks to his fears they can't go further than a couple of hight altitude F***s. and his anger grows bigger when he his plans for their next meeting were changed.
They both know what brokeback mountain mean to them, it was the place where their bodies fell under the spell of love and where they became one and doomed, i have said this many times before. but they were one soul and each time they were together they were sharing their happiness, but sometimes that is not enough. and that is what happens to jack, this is not enough for him and since he didn't want to loose Ennis he stand it. he is forced to not tell his feelings to Ennis he tries on many occasions but the fact that he don't know how would Ennis react doesn't let him. Ennis meant his world to him and G'd knows that he is more than willing to leave his wife and his kid to be with Ennis, he don't care about the world and how they would judge him he don't care for money he just want Ennis.
Ennis is his sacred realm his soul is only and only Jack knows that but Ennis doesn't, he don't know that Jack love him more than anything that only a minute with him is a paradise for jack and I'm gonna quote a part of the short story when they were at the motel "Come on Ennis, you just shot my airplane out a the sky---give me something a go on" he was aware that he wanted Ennis so badly.
"I hope you know that if you don't never know the rest...." What is the rest? it is not about Randall or the Mexican prostitutes it is about how they missed each other, how they deeply love and how their souls went to a higher state of unity that can't allow them to be appart, how he love him and how he wanted to tell him that. how much he wanted to be with him and spent his last days with him ( :'( :'( :'( :'() jack was telling in a hidden language I love you bastard why you don't want to be with me. he was aware that Ennis was in denial of accepting his love toward him and he wanted to make him wake up of that state. this words hit him and were the ones that caused him to cry it was truth Ennis understood it but too late.....
