I do love that you love Aberforth in this. I wrote him because I know you do like him. Aberforth knows the deal from the start and Albus would know he knew and still they play each other. What a fucked up relationship. *sigh* siblings
And Sirius clearly still has the drive needed to survive--for Harry's sake. He loves like three people, Harry being one of them. They are the blood in his heart.
