Hastily becoming second in line to get the crown as the Black Heir wasn’t exactly expected for Regulus. Yes, he grew up in the royal Black family as Prince Regulus next to his brother, Prince Sirius, but he always figured there’d be a plethora of relatives before him when it came to getting the crown and becoming the King of France. Yet, he had been told everything, and Sirius practically pushed him to be first in line since he didn’t want to be King.
Which highly raised his ego, but he wouldn’t ever tell anyone that. Him and his esoteric ego. His family had their fair share of enemies when it came to other royal families, and he knew your family, the Baudelaire’s, were always balancing on that very thin line between enemies and alliances. He, of course, did not enjoy your presence, or your family’s, for that matter.
He believed you to be a cloy. He saw through you, and you two always bit at each others necks. Especially because you were the first in line for your family to be the Queen, and you’d rather die than bow down to Regulus. Not to mention, your lady in waiting always left some sly remark to him and probably tried to poison him a couple hundred times at dinners, and boy, that just heightened the urge to throw you off the side of a cliff whenever he saw you.
