I love you.
From the day your dear great aunt introduced us, throughout the days we made plans to acquire the Deathly Hallows, to take over – 'For the greater good', we said.
You knew about how I felt; I know you did. You took advantage of these feelings, to get me to do what you wanted. I was naïve, and young. Of course I did as you wished. I loved you. I still do.
Even during that fateful duel that killed my Ariana, my beautiful little sister, the duel that tore my already broken family apart. I will never forgive myself. It was my duty after my mother died to look after Ariana, and I let her down; the woman who died looking after her daughter. I let Aberforth down, the one who looked after her more than I did, her best friend, her favourite brother. I let down father, the man who went to Azkaban for his little girl. Despite everything, I couldn't bring myself to hate you. I still loved you.
Even in 1945; the year we duelled, the year I defeated you, you got send to Nuremgard, your own prison. Even then, I still loved you.
Even now, when I'm old, and helping a talented young boy to defeat a dark wizard perhaps greater than yourself. Throughout all the years, and the years to come, I will always love you.
