What's in a name?: a story of high implausibility. Very short, and very silly.
Harry listened as Hagrid explained about the name of the man who had murdered Harry's parents. And it really made no sense to him, at all.
"Hang on – is that kind of name normal in this world? It doesn't sound real, yeah?"
"Well," Hagrid replied, " 'e was a Lord and all that."
Harry's brow furrowed. "But Lords have old names – families or places, right? Is there like a place that is - what was it again? Valdimart? – or was it a family name?"
"Yeh know," Hagrid scratched his beard, pondering. "I dinna know. Never 'eard of the name outside You Know Who."
"Well, it's pretty obvious he has to have another name." Harry nodded with certainty. "I wonder what it was?'
"That's a real puzzler, 'Arry. Never thought u it like that, but yer right. " Hagrid nodded as he followed the conclusion of Harry's logic. "'E'd 'ave to 'ave a real name. No witch would name her baby Volde… well, you know. It's not a place, neither. "
Harry was quiet for a moment before coming to a decision about his family's arch enemy. "Well, I'm not gonna call him You Know Who because I don't. But if people don't like me saying the V word, I won't say that, either. How about the Puzzle… or wait… My cousin read these comics and one of the bad guys was the Riddler. So how about Riddle? I'm gonna call him Riddle."
Hagrid shrugged. "Suit yerself, 'arry. Now, lets finish this shoppin' afore I take yeh back tuh them muggles."
