he didn't love anyone, except possibly Fredersdorf

I'm still amazed that Fredersdorf rather than Wilhelmine was the exception. After years of abuse and faking love with the one person who stood by him and suffered with him, he suddenly acquired the ability to love at age 19, while imprisoned? But then never used it again?

Oh, wait, I'm trying to make sense of the senseless. Never mind!

But seriously, if he was going to only ever love one person, it would be either SD or Wilhelmine, imo.
