New scene, later that night. Camp fire dies down, coldness descends. Ennis, with only his blanket, chills (as Jack had warned), shivers, puffs, teeth chatter as he tries to keep warm. Wakes Jack with his snorting . . . annoyed, Jack opens the tent flap, yells . . .
JACK: ENNIS!
ENNIS: Whut?
JACK: Jus quit your hammerin' an' get in here!
Ennis sleepily get up, grabs his blanket, staggers to the tent knocking pot and pans on his way. Jack (cleverly?) scoots over, giving Ennis some room to lie down in the tent on Jack's right hand side. Then as Annie says "and in a little while they deepened their intimacy considerably."
