Ennis enters the tent at the coldest point of that night:
EXT: BROKEBACK MOUNTAIN, WYOMING: NIGHT (LATER STILL): 1963:
The moon is full up, notched past two in the morning.
ENNIS is dizzy drunk, on 'all fours, struggles to stand.
ENNIS
(weaving)
Too late to go out to them damn sheep.
(pause) .
You got a extra blanket, I'll roll up out here and grab
forty winks, ride out at first light.
JACK
(doubtful)
Freeze your ass off when that fire dies down.
Better off sleepin' in the tent.
(stands up)
But he staggers under the canvas, pulls his boots off, falls asleep on the ground cloth. Snores.
JACK follows, crawls inside his large bedroll.
EXT: BROKE BACK MOUNTAIN, WYOMING: CAMP: NIGHT (YET LATER STILL): 1963:
Coldest point of the night.
ENNIS shivers, teeth chatter uncontrollably.
JACK
(irritable, sleep-clogged)
Jesus Christ, quit hammerin' , and get over
here. Bedroll's big enough.
ENNIS, too cold to protest, crawls inside.
