Yeah, more like she trusts him but also knows him and the world at large, how it's effecting him at any given point. She trusts, but doesn't wear blinders to him either.
The thing is, though, that she's still not the Karrin we met back in the early books, and Harry is no longer the young punk of a Wizard, either. The romantic attraction was always there, and still is, but it no longer feels...well, the attraction feels natural but the idea of them acting on it no longer feels natural to me, not the way it comes across back around
Death Masks. Back then, even when he was with Susan, the Murphy relationship felt more natural than the Rodriguez one.
Now, though...that sense of them together as a natural development, at least for me, is gone. I still feel in in reread of the older books, but by the time of
Cold Days and
Skin Game, the idea produces more of an 'It's Too Late', reaction.
Maybe
Peace Talks will change my reaction, we'll have to wait and see.
But I suspect that JB will have to do
something about Karrin soon, if she's still going to play a major role in unfolding story. I suspect he'll find it necessary even if he doesn't plan it right now, simply because of the demands of the story.
