Hermione suggested going to the Hogwarts library each and every time, and Harry had to explain that he and Voldemort — he and Voldemort, who would have thought! — had already been there. And at the Malfoy Manor library, and at Grimmauld’s, and at the Department of Mysteries...On quiet days, it was a part of their routine: meet by the lake, argue for a bit, and then head to whatever library Voldemort deemed was most promising this time. Harry dragged along, well aware that he had little to no chance of breaking the loop on his own. Voldemort was exceptionally skilled in complex magical arts, spoke several foreign languages, and had great research ability — Harry, on the other hand, could probably only boast of being able to fold paper planes so perfectly that they could fly through the library like fighter jets.
