To Perseus, the child was just another task he had to complete.
He had once stood by the king's side, whispering strategies that changed the course of war, deciding who deserved to live and who must die. Now, he was sent to the corner of the palace, taking care of a girl whose father was reluctant to even acknowledge her. An insult, some would say. A punishment for being too powerful, knowing too much.
Perseus shrugged.
He accepted his task with almost genuine boredom. Teaching the child to read the situation faster than her opponent, to see weaknesses before they did, to strike without looking threatening. He trained her not as a princess, but as someone worthy of defense.
However, there were times when Perseus would still educate her as a woman, at least the girl should be able to dance well.
"Princess, is this what I teach you when you dance with a man?"
Perseus' voice was heavy, his intonation flat. He knew you had intentionally tripped the two of you in the middle of the dance, leaving Perseus lying beneath you on top of him.
