I don't run in Lydia's circles in-game but every time I see her pop up something I'm immediately sitting up and interested. She has such a particular point of view and you work her strange mash-up of genres very well into the game in ways that are surprising and fun to read.

And on a shallow note I just love that icon of her tilting her head in confusion and disdain. I don't know why. It just feels sticky to my brain.
