Thanks for digging that quote up. Should put the good justin theory to bed.

I always thought that Sue would appear again when Harry needed something big to take on a horde of faceless enemies (fomer?).

Marcone does not necessarily point Harry in a specific direction or at a specific enemy (example Changes: Harry was already pointed at the Red Court). He does give Harry information on occasion which serves three purposes usually. Number 1, it keeps Marcone in the know when it comes to potential fallout on Harry's cases. This allows him to protect/expand his own interests (acquired the Velvet Room). Number 2, it allows him to subtly achieve a desired outcome by giving Harry specific bits of information (removal of Vistor Sells). Number 3, it allows him to try and build goodwill with Harry (futile as that may be).

As far as Maggir Sr. goes, someday I am going to go through each book with a notepad and record every mention of her ever made.

You may have that chance depending on when Peace Talks comes out.

The trick is to either beat the nest without being detected by the swarm or by giving the swarm a more visible/appealing target to attack. Cowl is managing to do both pretty well so far.

I also want to know what people see when they soul-gaze Harry. Maybe we will get a peek via someone else in the upcoming books.

Both logical loves to burn Thomas, but why kiss him in the first place. She kissed Harry's head to heal his head wound. She kissed Susan's head to seal their pact and take away her memories. I think there is another motive for that kiss that was not revealed or has not been revealed yet.
