He leaned casually back against whatever happened to be behind him, shaking his head lightly. "No idea. Hagrid was right persistent, though. Can't talk him out of anything if Dumbledore's behind it." And since he had already gone against Albus with the whole secret keeper thing, he hadn't felt like he'd had much of a leg to stand on.
Maybe he could convince Dumbledore to let him raise Harry, if he ever got back.
Managing a little smile of his own, he otherwise didn't comment about Prongs. He felt like he was stuck in this weird place between mourning the death of James and hoping like hell he arrived here. Hoping he showed up here was slightly less painful, though, so that was winning out most often.
"Don't know the whole story about Voldemort, yet. I ... I thought he'd been killed at James and Lily's, but Lily said she was talking to Frank and Alice's son here and he said that Voldemort wasn't actually dead at the time. Supposedly he came back later and Harry defeated him. Afraid I don't really know anything beyond that and it's third hand information," he raised his hands, spreading his fingers as he shrugged.
