I mentioned it once, but not in this much detail, and I'm sure it got lost in the flood of information. This fandom is like drinking from a firehose!

Seydlitz, btw, is the one who got wounded in battle, recovered from his wound, and right before he returned to active duty, wrote to Fritz asking if he could marry someone who could act as his nurse in the hypothetical event that he got injured again someday.

Fritz: Sure! I'm all about marrying for the distant prospect of future medical care. I know you would never get married because you *wanted* to...right?

Seydlitz: Nope, not a bit of it. I mean, what about my entire life history would make you think I'm attracted to women? I'm as pure a Potsdamite as you and your brother! Just like your chamberlain boyfriend, who also married a nurse.

Fritz: I find this argument totally convincing. Permission granted!

Seydlitz, sotto voce: Fritz will let you marry a prospective nurse, spread the word!

ETA: Seydlitz also the one about whom Fritz wrote to Heinrich that his death could have been avoided if only he had listened his doctors like Fritz notoriously never does.
