Neville clenched his jaw, sympathetic tears burning the backs of his eyes. It was horrible to watch someone try to hold himself together like this. It was even worse to see someone that he'd looked up to as a child lie, instinctively, as if he'd done it a million times before. He couldn't even bring himself to be angry, or furious, or vengeful. It was a horrible scenario, one that was about to play out before their very eyes over the next several months.
And all Neville could do was feel sorry for Remus, pity him for the lot in life that he had been stuck with. And -- there was the anger, the pure fury that he remembered from his years as an Auror when faced with the sheer depravity that Fenrir Greyback had exhibited. He'd attacked a child, given him no choice but to live his life as he had, and this was the result. A young man, little more than a child, living hand to mouth as one of the most feared creatures known to wizard-kind.

He found himself with a hard core of determination to keep Remus alive, understanding that the person before him would be the last person to intentionally hurt someone, and that the wolf within him was not representative of Remus Lupin, human. Greyback had made himself and his wolf one and the same, but Remus had not. That must be preserved. "What happened?"
