This is set sometime before Sirius dies.

"Hey Remus?"

"Yeah Harry?"

"I was just wondering, umm, well, why am I named Harry?"

"Well, Sirius was actually the one who suggested it."

"Really?"

"Yeah. He came to meet you right after you were born, before Lily and James named you. Some babies are born bald, but you already had messy black hair like James. And Sirius said, 'He sure is a hairy baby isn't he? You ought to call him Harry.' He was joking, but James thought it was funny, and Lily said it fit, so there you have it."

"Sirius named me?"

"Yep. Scary thought, huh?"

"Yeah."
