Just a bit of a plot bunny that popped into my head, and I felt the need to get it out into the world. Hope you like it.
"Dad, where did you get my name?"
"Well, Albus Dumbledore was one of the greatest headmasters Hogwarts had ever known--"
"No! Not that name, my middle name?"
"Uh, well, he was a man that really cared for you grandmother, Lily, my mum…"
"That's not what I was hoping for, Dad."
"I'll tell you more when you're older."
"Mum, tell me Dad's joking and there's more to my middle name than he had a crush on Grandmum Lily."
"He was a double agent, a spy. Is that good enough for you?"
"Eh, I guess that's okay. You didn't pick the name did you, Mum?"
"Love, if it was up to me, your middle name would be Remus."
"Gran-Molly, you know everybody, what was the guy who I've got my middle name from like?"
"He was, erm, interesting…"
"Was he handsome?"
"I wouldn't go that far…"
"Athletic?"
"Not from what I saw."
"Yeesh! What was he?"
"He was quite brilliant."
"I thought the guy I got my first name from was brilliant."
"They both were."
"Oh, that's exciting."
"Grandpa, you'll tell me the truth, won't you?"
"I'll do my best."
"What was the guy who I got my middle name from really like?"
"Uh, well, I didn't really know him, never had him as a professor…"
"So he wasn't all that great and you just don't want to tell me?"
"C'mon, I'm doing my best…"
"Auntie H, you've gotta tell me what the guy who taught you potions was like."
"The man who you got for middle name from? Really, I don't know if it's my place."
"I'm asking you, therefore I'm putting you in the place."
"Well, he was very unusual in his teaching methods…"
"How so?"
"Uh, he wasn't particularly kind."
"He call you dumb?"
"Well, not exactly, more like a know-it-all who didn't know when to shut her mouth."
"Oh."
"Uncle Ron, you'd never lie to me, would you?"
"Oh, no! I heard you've been asking questions! I'll take no part in this!"
"Why not?"
"Because I'm not gonna be the one to tell you what a git he was! Ah, bugger."
"Uncle George, you're my last chance, I really and seriously mean this, will you tell me what the guy who I got my middle name from was like?"
"Sure I will! He's the git who cut my ear off!"
"What?"
"Sliced it right off, used dark magic! And your parents named you after him!"
"That is so…"
"I know."
"Cool!"
"Uh, what?"
"The guy was a real bad-ass! I mean, sorry about your ear, but wow!"
"You totally missed the point of me telling you this."
