Pastime, not past time.
Remy and Siri are horrible fanfic nicknames. Remy doesn't even make sense as a nickname: it's no shorter in speech than the name it replaces, and if pronounced the same as the real world name Remy uses a completely different e sound than the name Remus. The e in Remy is like the e in them, while the e in in Remus is like the e in tea.
Making Remus a Pyromancer (an ability never mentioned anywhere for anyone within the canon) seems unnecessary and arbitrary. It could simply be an unfamiliar spell, rather than a completely new ability unto itself.
The idea that Remus is addicted to chocolate is another bit of fanon, and one that I feel diminishes the character. If he's hooked on the stuff, then having it on hand is the act of an addict. If he's NOT, then it's the sign of a well-prepared Defence teacher acting with forethought to have a remedy on hand when he knows that there are to be Dementors at the school.
Why would everyone look at Fudge after that bit about Hagrid, and why would Fudge look guilty? Sure, Fudge locked up Hagrid in Azkaban BECAUSE of his earlier expulsion, but that's not what's being mentioned here. Only the expulsion is, and that happened DECADES before Fudge was in power, and was decided by the then headmaster (Dippet), not the Ministry at all.
Author's response
Well, I'm basing the nicknames off of the fact that before they came up with the Marauder names, there had to be something they called each other to get a rise. And the pyromancer thing is just me trying to throw something new into these stories. And while it was never mentioned in canon, there are a lot of things that weren't mentioned in canon that people create fics off of (ditto with the chocolate addiction, or not .
And people would look at Fudge because he only went off of what someone's past record was, and since explusion and Azkaban are two entirely separate things, the reaction might be a bit stronger. Also, Dippet and the previous Minister arent exactly present at the moment to receive the glares.
Wow, that was the longest response to a review I've written - thanks!
