I KNOW you didn't choose the name after D.H. Lawrence's wife that he convinced to run away with him by comparing her to his mom BUT that's all I can think of when I read the name Frieda

I'm gonna steal some of this now, she ran away from home (see: moved out like a normal adult but she was dramatic about it) to join The Theatre bc she fell in love with a stagehand for a touring opera company and MvK was weirdly ok with it bc 1. He spent years paying for singing and acting lessons he's just glad she's using them and 2. She's such an eccentric character that he's like well of course she's gay she's a theatre kid.

Manfred von Karma mentions a grandchild (granddaughter?) at one point so it's a fair assumption that he has at least one more child and through several leaps of logic I have decided that this third child is a high maintenance lesbian opera singer named Freida von Karma.
