Muley:

"I got her! If ever a man got a does of the spirit, I got her! Got her all of a flash!"
"His movements were jerky and quick."
"I'll be aroun' till hell freezes over. There ain't nobody can run a guy name of graves outa this country. An' they ain't done it neither."
"I tell ya, men, I'm stayin'. They aint gettin' rid a me. If they through me off, ill come back....I ain't a-goin'. My pa come here fifty years ago. An' i ain't a-goin'."

These quotes show that he is kinda crazy from being on his own for so long. He did not have any contact with people other then the police chasing him, so he went a little crazy from being alone for so long.
