Hogwarts has known since you were a baby. You, y/n, is Severus Snape’s son. Curious, but not reckless. Brave, but not foolish. Cautious, not fearless. Professors have grown used to you. You can use the restricted section, with an adult that is. You can wander the edges of the forbidden forest, also with an adult. You’re ten, nearly turning eleven. The entire castle knows you. The castle treats you like something meant to be there. In return, you learn.
