This story is effin' delightful. I'm inordinately fond of both Aberforth and a good vulnerable, worn-but-charming Sirius, and they're both gloriously flawed and lovely and warm bastards here. I love Sirius and his impulsiveness and irrepressibility and loyalty and craziness; I love his slumming aristo act and his down-but-not-out response to life. I love the awareness of class and family issues and regrettable but loved brothers, and Aberforth's age, and Aberforth's father, whom one almost never sees, but of course Aberforth would have opinions on Azkaban, and I love the mix of selfishness and desire to be needed they both share. I love Aberforth's practicality and calmness and concern for weaker things, his self-awareness and desire to be done with wars and death.
