This is a passage from a novel:
"No," he said again, standing up straight and wiping his palms on his pajama pants. "We've already got plane tickets." (Both quotes are Neal's)
"Neal, I'm serious. I can't miss this meeting." (Gerogie said this)
"I know," he said, turning toward her. His jaw was set. Permanently
What does "his jaw was set" mean?

Bridge to Terabithia Chapter 3:
Jimmy Mitchell’s jaw was set. “I won, Fulcher. You couldn’t even see from way back there.”
I guess "to set one's jaw" means to show his or her determination.
