A Lone Wolf Remembers

Harry didn't escape a transformed Professor Lupin unscathed. While he didn't get infected he now bears scars from his encounter with the werewolf. It is safe to say that the course of events would change. Harry becomes depressed and Lupin can't forgive himself for hurting Harry. Begins at the attack and ends in Deathly Hallows, includes time-jumps. AU, kinda smart!Harry
