You don't need to know the canon to love this, but if you just can't bear the thought of reading it blind, you can go study this thread (aka "A Foolish Mortal Tries to Avoid SGA") first.
Hee! You linked to it. And when it comes to SGA, resistence is indeed futile. *g*
In a week or two, when I've finished my exams and essays and the semester, I'll add some stuff to that thread: other characters, other races, etc. Did you have any more questions you wanted me to answer when I do that?
