Dr. Walker cuts him short and explains that he doesn't expect anything from Gruenwaldt but only asks he try to understand that life and death situations occur daily to the extent that he can't remember them all. Gruentwaldt eventually gives grudging thanks for the saving of his life but makes it clear that he will still carry a hatred of his saviour for the loss of his wife, which Dr. Walker sagely replies "then that is something which we will both have to live with."
