Time Heals All Wounds?

Chapter 7 is very important because it shows a change in Billy. It shows that he's aware that the war has an effect in his daily life. He remembers an event without time traveling: "Billy thought hard about the effect the quartet had had on him, and then found an association with an experience he had had long ago. He did not travel in time to the experience." (PDF)

Billy's focus will probably always be on war. After his experiences there, it's normal everything will remind him of Dresden. But the fact that he doesn't time travel and still remembers, suggest Billy is healing from his war experience.

When there's a life changing experience in your life, you usually compare everything to it. It usually appears everywhere. With my grandpa's cancer, I see articles and commercials about cancer everywhere. They were probably there before, but I didn't link them to anything. The same happens with Billy. He wouldn't have linked the Febs with war if he hadn't been in it. Hearing the Febs, made "His mouth fill with the taste of lemonade, and his face became grotesque, as though he really were being stretched on the torture engine called the rack." (PDF)

Will Billy be able to live a normal life after the war? I believe that with time, he'll live without being terribly affected by the war, just as he's leaving the time traveling behind.
