It seemed to keep showing how close in color their hair is! I kept thinking that since she was little... I think it's true!!
I think he very well could be. Or at least was romantically involved beatrice. In the novel, he even walks Rieta down the aisle on her wedding.
I'm so happy to read that last line because morbidus is raising some serious death flags in the last few chapters and I'm SCARED. I want to see Rieta's joy when she realised she has family left in him and they leave happily ever after.
Huh, now that I think about it Morbidious and Beatrice seems awfully close. Any chance Rieta is their daughter? If that is even possible?
Nah probably just my wishful thinking. Headcanon to me for now haha
