Scientists will save us all.

This note is scribbled above Johnny's last letter, to Frances. It reveals Johnny's utter faith in the pure sciences as well as his hope that, one day, science will provide help in ways it could not help him. Watching medicine consistently fail to cure him must surely have been debilitating to Johnny's confidence in science, but just as he survives through courageous optimism and refuses to sink into hostility, he still believes science will someday defeat the world's ills and harbors no resentment against that which failed him.
