Princess Tutu Fans

Hey everyone! I have one new inquiry and one old discussion topic that I never got around to posting, so get ready for a double whammy!

1) I was watching the prelude to Episode 21, and for the first time, I really paid attention to the fact that the 'Once Upon a Time" story included the fact that Drosselmeyer wrote stories for "The King, the Nobility, and all the Kingdom's rich" before they started fearing him. This isn't that unusual, and this has NOOOO solid basis in canon, and is more of a discussion point, but I started wondering if the Prince Siegfried in the Prince and the Raven was the son of the King who used to go to Drosselmeyer for stories, and whether putting the Prince in the story was Drosselmeyer's way of getting back at the kingdom who had scorned him. Like I said, no canon basis, but a fun thought, right?


2) This is music related. I was playing a game named Catherine and there was a stage playing THIS SONG (no worries, no spoilers), and I could have sworn I've heard it in Princess Tutu. Does anyone know when/what episode it might have played in, or alternatively if I'm just MAKING IT ALL UP IN MY HEAD?? Inquiring minds want to know and any help would be much appreciated!
