Chapter 45 - Third Year - Noble and Most Ancient

After the confrontation with Snape in Hogsmeade, Sirius locks himself in the bathroom for hours, devastated by the realization that his family has truly disowned him. Remus uses blunt honesty to get Sirius to open up, and they bond over their shared experience of family rejection. Weeks later, as tensions with Slytherins escalate and blood-based slurs increase, Remus devises a brilliant revenge plan to magically alter Snape's speech, replacing his cruel words with harmless phrases. The chapter ends with another confrontation involving Regulus and the Slytherin quidditch team, solidifying Sirius's determination for comprehensive revenge.
