"Expecto Patronem’. Pansy Parkinson, it’s Hermione Granger. I know you owe Severus a Life Debt, and I need your help to twist Fate back to my reality so that he may live again and you can be cleared of the debt. Meet me in your room, where I will play your favorite song by The Cranberries so that you know it’s me, and that we’re friends from when I’m from.
