You heard about the sequel right? Bareback on Brokeback?
Ennis Del Mar moves to Pendleton, Oregon and gets a job in a woolen mill. The fuzzy wool fibers floating in the air and the smell of wet washed wool routinely send him into eroctic daydreams of his days of wonder with Jack. He's tragically killed while dry humping a cloth rolling mill and becoming...er... entangled and crushed to death.
Jack, upon hearing the news of Ennis's untimely death, loses it and returns to sheepherding on Brokeback Mountain. While doing his job and daydreaming of Ennis, he too becomes enthralled with the smell of wool and starts some new romances. Before long, he can no longer remember Ennis's face but does own the area's largest collection of rubber knee boots and velcro gloves.
It's kinda a happy ending as nothing to baa-aaa-aaa-aad happens once Ennis is gone.
