Deathly Hallows: Part 2 Use
Does it need mentioning that Severus Snape may have used this spell during his duel with McGonagall in Deathly Hallows: Part 2? As the "fire spells" never happened in the book, as far as I can remember, it shouldn't really be considered canon, and therefore should not be listed under the Known Uses, right? Just wondering, I wasn't sure if I should remove that or keep it up, thanks. AlastorMoody 17:34, August 8, 2011 (UTC)
