Questions regarding BtVS canon

[estepheia]

Is Xander's Uncle Rory, the taxidermist, the brother of Xander's dad or mom? Do we ever find out what kind of job Tony Harris has? IMHO Xander's dad has the snide behaviour of a man who's forced to be polite in his job, like a used car dealer, who hangs up his charms and manners along with his hat, when he steps into his home. What do you guys think? What kind of job does Tony Harris have?
And how readily do fourteen-year-olds use the word 'Fuck' in 1996 California?

And yes, the questions indicate that I'm writing today, or trying to. I'm working on the-fic-that-no-one-reads AKA Four Fear. As far as I can tell only two people read it. *waves at brandil and pinkdormouse*. I try to console myself thinking that if I get it finished another 5 or 6 people will give it a shot. That will teach me never to write another story that a) has no Spike, b) has no porn, c) prominently features an original character... Sorry if this sounds bitter... but it is a bitter pill when you're writting a story you care about but it gets the cold shoulder as though it were the love child of Attila the Hun and George Bulwer-Lytton...
