Gah, I like the word "queen" because of etymology. I chose it for my long-Buffycentric fic. The phrase really assumes other meanings changing king with queen. I think it's because of the hystorical values of these words.

I've read it in fanfiction as well, all of which have been far better written and better developed than the comics but the solution still never quite works for me no matter how elegantly or skillfully it's presented.
For me too the spell is an endgame. I think it's the best possible solution in that situation and I don't see why taking away the power from the girls after. Everytime Buffy makes the "Chosen" speech I could cry ugly empowered tears. It refers to all of us, I think, to take the power in our hands and be brave. It's really inspiring.
