Billy seems to intuitively sense the shift in Old Bill when he randomly decides to take his old friend to breakfast. But even though some things change, others stay the same—Old Bill still wakes up cussing. The fact that Old Bill plans to take his ghosts with him shows that the tragic events of his past still mark him. But he’s leaving town for the first time in years, showing that he has begun to rediscover his sense of purpose. And, perhaps most importantly, he’s only been able to do this since becoming friends with Billy, who encouraged him to stop drinking, showed him love and respect, and will take care of Old Bill’s house—and its memories—while Old Bill travels.
