[Randolph and his servant are at a military hospital, where Randolph has discovered that the amnesiac soldier there is not his son John] Charles Randolph:

A wise man would remember that this soldier was in John's regiment. If his memory returns... he might tell sahib what happened to his son. Perhaps sahib would learn that John is in British hospital now wishing a kind man would take him home... away from his pain
