"Bring nothing," Walter said. "Just what you're wearing. I'll give you the rest." (31.74)
Walter commits a huge act of love by taking Max into hiding and helping him find his way to Hans. And that's what friends are for.
Quote 2
"Sorry it's taken so long. I think people have been watching me. And the man with the identity card took longer than I thought […]." (23.19)
Max's best friend Walter Kugler is about to go to Poland to fight on the side of the Germans. Of course, he's been drafted and wouldn't have gone of his own accord. It must make him feel like a criminal. By helping Max, he's committing a crime with a death penalty. But, we bet this doesn't make him feel like a criminal in the long run.
