When Dennis is talking to Mr LeBay...not Roland, but Rollie's younger brother George and he tells Dennis about Roland, about his anger, the letters he wrote, about how he was married to the army, married to the ****ters...and he speaks of the letters home...they were his suspension bridge, his novel, his symphony, his great effort. I don't think he wrote them to get rid of the poison in his heart. I think he wrote them to spread it around.
Another...through Arnie's stream-of-consciousness...he has just pulled into Darnell's garage...this after the car ride and the apparition or whatever it was, the rider...that was now gone...though the smell was still there. Arnie reasoned If you hung around the ****ters for long enough...everything started to smell like ****. And that made them happy, of course.
