Thanks for the review. In the storyline, Severus (or, rather, I) needed a fast solution and, as Harry views McGonagall as more of a Great-Aunt figure, Albus has proved himself untrustworthy (in Snape's eyes) and Severus hasn't yet been able to repair his relationship with Harry (and, indeed, doesn't know whether it's possible) the candidates are reduced to four: Sirius, Hagrid, the Weasleys and Remus. Now, casting aside Severus' opinions of Black (who is, in some ways, even less mature and more dangerous than Hagrid (considering his daredevil attitude), Sirius is a man on the run and, therefore, would be hard pressed to create a secure location. Remus is a werewolf, nuff said, and the Weasleys, while being good parents, are not really able to provide an appropriate level of security and, besides, Ron is at varience with Harry. Hagrid, on the other hand, lives in Hogwarts (and could take a suite inside the castle during the holidays), is very strong, has a natural defence against curses and, most importantly, he loves Harry and Harry loves him. As for Aberforth and Severus, I've always thought that the two astute, no-nonsence men would probably have a grudging respect, if not a positive friendship, and I can see Severus letting off steam about his students (and employer) to Aberforth's sympathetic ear (after all, as a DE, he has to stay in character ;).
