Jack Twist (Jake Gyllenhaal)’s Timeline and Summary

Jack falls in love with Ennis Del Mar on Brokeback Mountain.
They herd sheep in the daytime and at night, well, when the tent's a rockin'…
The next summer, Jack attempts to see Ennis again, but Aguirre, the man who owns all the sheep, will not give Jack a job.
Jack returns to Texas to ride rodeo.
He occasionally hits on other men in the rodeo, but he has to be careful not to come on too strongly where his advances may not appreciated.
Soon, he meets and marries Lureen Newsome. They have one son.
Jack later reconnects with Ennis and resumes their long-distance affair.
The distance is both physical and emotional. Jack grows frustrated with Ennis's repressed emotions.
He often travels to Mexico, where male prostitutes are readily available.
Meanwhile, at home, Jack sometimes clashes with his father-in-law.
But he tells the old man off at Thanksgiving, and finally gets to carve the turkey himself. (A big deal in Texas.)
Soon, Jack breaks it off with Ennis, and starts an affair with a new man in Texas.
Off screen, something goes terribly wrong, and Jack dies.
