Why does Jack hold Brokeback Mountain responsible for their passion? What was it about that summer that couldn't be repeated?
@royandronnie - your summary is bulls-eye. @CellerDweller15, you also tapped into the alcohol dropped the walls, lowered the inhibitions and and loosened the pants.... so to speak.
If I flip this around, perhaps if there had been a bit less liquored up while up on Brokeback, maybe Jack would have NOT placed Ennis' hand on his groin which initiated the FNIT or maybe Ennis's inhibitions would be have been higher. After the FNIT, we see the "loving dozie embrace", the shirtless playful antics and maybe the bear attack..(sorry I cannot remember that sequence exactly. Then we have the willingly done, SNIT. So, being up on Brokeback, a supposedly safe location, out of the public eye, allowed their passion(s) to develop at different rates.
We also see Ennis's
passion at least twice: once when punches Jack right before they descend from the mountain and the 2nd time when Ennis is kneeling in the alley punching the wall - sick in pain of "losing Jack..."
That summer was unique from the vantage of two younger men, one of which likely had
never let his homosexual feelings surface (Ennis). There's a certain innocence in Ennis's perspective. We know Jack had earlier male partners - maybe only short durations or one-night stands. From Ennis's innocence or "first time" vantage,
that was unique to that time on Brokeback - that first summer and simply could never be repeated. Their later fishing trips were "good" but their first time,
could only ever be "up on Brokeback..." V.
