I've always seen Xander as the sensible one, with an innate common sense. He may not be book smart, like Willow, or even Buffy, but he is the one who sees.
I'm so glad you like my Giles too. I love drawing out the relationship I always thought was there, because when Xander was in trouble, he went to Giles for help, where the others... not so much. *g*
Thank you for your lovely comment.
