Was totally shocked with the pairing - almost decided not to read it, thinking it would be comically grotesque. Instead, it's so tender, & moving & deftly written - so healing, & it works so well. The sense of Aberforth as gruff & kindly & sincere that comes across in his interactions with Neville in DH, is amplified here, & this line is so perfect: "He'd had his share of cast-offs in his life, worn out clothing and broken toys. Albus never was careful with his things. If nothing else, it had made Aberforth a fair hand at mending.", this says it all. Wonderful.
