Is Marci really now described as gorgeous? I checked, and... no?
Mousy haired is not a compliment. 2nd-cutest werewolf depends on how cute the others are, and while Andi (1st-cutest) is gorgeous, (but wasn't originally, she used to be too big for Dresden's taste) Georgia is not described as particularly pretty.
Nerd wish fulfillment:
Involved in a FFM relationship
Effectively has a lightsaber
Outhinks everyone else. Can do stuff that (usually) only the hero can do because he's smarter than the hero.
There's probably more...
