They rarely studied for their shared courses, however. Instead, they pulled every book imaginable on bonds and bonding rituals from the restricted section, courtesy of the password Hermione coaxed from Slughorn one afternoon. It was scary, really, how easily she’d been able to get the information out of the old professor. He seemed to still want to "collect’ students, and still had Hermione in his sights, being a war hero and all. Unfortunately they had yet to come across any information that explained their particular set of symptoms from the bond. It appeared they were at an impasse. Just that afternoon, their "study session’ ended in a particularly heated argument regarding the possibility of a celestial aspect to the bond. She’d argued it was a ridiculous notion, while Draco argued the merits of the theory, given the aspects of a celestial soul bond as noted in the book he held. Hermione refused to believe it– the celestial bonds all held some aspect of blood magic. There was simply no way. Blood magic was thought to be a grey area, of course, not quite dark but not light either. The notion was absurd, in her opinion.
