Harry looked at his two friends. "Guys, this is a Horcrux. I know it."
Ron looked unconvinced. "Are you absolutely sure, Harry? Because I don't want-"
"I am absolutely sure." Harry said as he took off his jacket.
Hermione sighed. "OK, Harry. Go ahead. Ron and I will be at a safe distance, watching anything other than you - I mean, watching to make sure you are safe."
Harry did not seem to have heard his friends as he continued his preparations for the one thing that they knew would destroy a Horcrux. Fiendfyre was effective, but the process used to cast the spell...
A short distance away, Ron and Hermione stared fixedly at a nearby mountain.
"You know," Ron said casually, "those clouds look like they might snow on us later."
"I think you are correct." Hermione said absently. "We'd best find a new place to pitch our tent, we don't want to be stuck here."
Both of them searched for something to take their minds off what was happening behind them as Harry destroyed the Horcrux.
The Boy-Who-Lived had finished his preparations. He was now wearing a green skintight spandex unitard and false, thick, black eyebrows. His hair had been magically restyled into a bowlcut, very different from his usual rat's nest. He frowned as he spoke the words to cast the spell.
"FLAAAAAAMES OF YOOOOOOOUTH!"
Author's notes: Yet another fragment inspired by a discussion in a fanfic Yahoo group. This one revolved around the fact that the exact incantation for Fiendfyre is not actually given in canon (at least, not that I and everyone else on the group could find). This lead to speculation as to what it might be, and of course the jokes start...
Oh, and disclaimer the second: I own no part of the Naruto franchise either.
