Oh, Harry...

I'm rereading the series for the first time, and I got to the passage in Storm Front where Harry talks to Karrin at her office and she brings him a cup of coffee and his response is something close to "Karrin, you're an angel." And all I could think was "Oh, Harry... If only you knew..."

You think Jim Butcher had this planned from the beginning? You think he was just smiling to himself with his devious plan to rip out the hearts of millions 12 years and 16 books later with one simple repeatable throw away line? (pun intended)
