Break the Cutie: His Tear Jerker of a backstory. He used to be the doctor of a small German village, but resorted to unfollow orders and steal medicine and supplies when a very serious illness broke out in the town and one of the victims was his son. Not only he was jailed, but said son was left in a wheelchair and his wife, despite still caring for him, left the place with said son. Once he was released from jail, he saw the Dandelion Troupe and joined it.
Secret Keeper: As a friend of one of the Premingers's retainers, Miss Applefield knew more than one detail about Nadja's origins though it's not clear how much. She did know that Colette was an Ill Girl not expected to live for long, but didn't seem to know who she exactly was, nor that she ultimately lived through (at least until she got the letter).
Chekhov's Gunman: Actually, Rosemary was clearly seen in the first episode and in the background of almost all the Applefield orphanage flashbacks. We just didn't know that her and Nadja's bond was deeper than that.
Graceful Loser: When she's definitely defeated, she aknowledges it without protest.
Pet the Dog: Her words of advice towards Nadja before she departs from the mansion, leaving her on good terms even.
Plucky Girl: Her evil plans to become a princess failed in the end? Pfft, the life of nobility was boring and restrictive anyway. So she vows to move foreward and work hard to earn her happy ending, becoming a princess on her own terms.
Twin Switch: Tries to pull one when he refuses to say that he's not Black Rose and is willing to go to jail for him, since BR is actually his brother Keith. Keith himself is very disturbed by the idea of Francis paying for his deeds, as he remembers that Francis often covered up for his pranks when they were kids and recognizes the very unhealthy patterns immediately.
Rebel Prince: All we know is that he walked out on the family after the death of the Countess aka his and Francis's mother.
Lovable Alpha Bitch: Yes, she's proud and rather snobbish. But she truly loves Francis, never lies to Nadja and even supports her claims, and once she sees that Francis does love Nadja, she quietly leaves.
Gold Digger: Despite being very rich already, he's hinted to be at first interested in Julietta solely because of her Blue Blood. Julietta herself seems to be scared of him, and Nadja immediately calls him out on it.
Uptown Girl: He once loved a young woman from the aristocracy, and they eloped to dodge a Parental Marriage Veto. She turned out to be an Ill Girl and died after a brief marriage. Raphael still blames himself for it at the present time.
