Did NOT see that coming.  Quickly:

Butcher has said that the books are the worst day of Harry's year. That said, IF Karrin and Harry are going to get together, better it happen off screen.  Also, parenthood is about invested time, not grand gestures.  His relationship with Maggie belongs there, too.  Karrin comes out for the weekend, bringing Maggie and they build campfires, go for walks, do homework.  LARP with the Alphas.  Butcher really GETS the repetition = depth thing.  And I believe that this is what will allow reality to survive the apocalyptic trilogy.  (Love, Harry's love for the reality that encompasses his partner and child.)  Did anyone else notice Murph and Harry just got married there.  Now they just need to have sex.

If Harry is going to be living on Demonreach, he's going to need a fast boat or a short cut.

Aww, poor CatSith.  I liked the nasty kitty. 

The Mouse greets Harry.  Onions, I swear someone was cutting onions in my room at 3 in the morning.

Unrelated to the +/- with Harry, I think Murphy is due for an upgrade, either via sword or Odin.  And I'm sure Butcher will do this in the worst way possible.

Came here for the Deeper wells stuff.

A strange confluence of Spike/Harry/James Marsters being both.
