"And the man breaks."
"He turns and runs, or crawls off afterward over the corpses of the slain, or steals away in the black of night, and he finds someplace to hide. All thought of home is gone by then, and kings and lords and gods mean less to him than a haunch of spoiled meat that will let him live another day, or a skin of bad wine that might drown his fear for a few hours. The broken man lives from day to day, from meal to meal, more beast than man. Lady Brienne is not wrong.
