The passage is on 79 when they were talking about ditching Blevins:
Meanin this is it. This is our last chance. Right now. This is the time and there
wont be another time and I guarantee it.
Meanin just leave him?
What if it was you?
It aint me.
What if it was?
Rawlins twisted the cigarette into the corner of his mouth and plucked a match
from his pocket and popped it alight with his thumbnail. He looked at John Grady.
I wouldnt leave you and you wouldnt leave me. That aint no argument.
You realize the fix he's in?
Yeah. I realize it. It's the one he's put hisself in.
They sat. Rawlins smoked. John Grady crossed his hands on the pommel of his
saddle and sat looking at them. After a while he raised his head.
I cant do it, he said. ------ What can't Grady do?
