As for what I said before, it wasn't just Gourry who acted like he'd never heard of Zanaffar before(that would be expected) but everyone. Lina had heard of it before so she could explain what it was to the others (and the audience, of course), but none of them acted like they had actually fought the thing before, which was the main battle of the second half of the first season. Not something you'd just forget. Also, just so everyone knows, I felt the need to make sure I wasn't remembering wrong and saying stuff that was incorrect, so I popped in my dvd and watched where they explained Zanaffar, and sure enough, they acted like they'd never come across it other than the story. That's all I needed to convince me the writers were trying to replace the second half of the first season with (R)evolution, or at the very least, pretend it never happened. That disregard for the Slayers history irritates me greatly every time I think about it.
