Kinsey will be diagnosed with antisocial personality disorder.She shows a lot of the symptoms of it. Most damning is that even though she can still love and care for people, she can't empathize with their pain or be worried about them. The closest she can get is being angry on their behalf. Nina Locke is about to get another phone call that'll make her very unhappy.
Detective Mutuku is going to have a swordfight with Dodge.And it will be awesome.
Rendell Locke's final confrontation with Dodge took place on stage during The Tempest.Since it involved the dramatic use of so many keys, the memories of adults could only explain it to themselves by remembering it as part of the production. This also made them not remember that the group was fighting. Judging by Professor Ridegway's flashback, Rendell Locke fought with the Crown of Shadows and used the Anywhere Key somehow. Dodge seems to have made himself larger and more muscular (but not Giant Key-sized) and Rendell looks like he made himself older. Also, Kim Topher may actually be flying.
There's a Chekhov's Gun in the flyleaf of the hardcover Crown of Shadows.The cross-section view of the wellhouse clearly shows a hatch at the back of the cupboard, opening into to a shaft leading down off the bottom of the page. Ten to one says that will get explored at some point. (Question: Is this more accurately described as Chekhov's Gun or as Foreshadowing?)
The Eldrich Horrors beyond the door live in a dimension beyond time, and can see into the human realm.This Troper was annoyed at first that apparently Benjamin Locke made keys that included symbols he'd have no familiarity with (A ying yang? DNA?), but then I remembered that apparently the whispering iron, well, whispers. The door demon parasites can see into the human realm and don't have any respect for chronology, so of course they throw random symbols onto the keys that don't make sense for a moderately-educated 18th century blacksmith to know.
The real reason Erin Voss only says "white".It occurred to this Troper when reading Clockworks #5. Dodge with parasite comments that Rendell will never love Erin because she is not white. While this might at first just seem to be a remark to sow discourse, Erin probably believes this as well. Later on, she only says "white", but not only because her empty head is completely empty and white but because it reminds her of everything she could never have and now can never have.
Tyler Locke will make a soul key.Counterpart to the head key, it allows access to the soul, and would let them get a demon out of someone.
The reason Dodge's echo first appeared in the Wellhouse.I keep on wondering why Dodge's echo would be in the Wellhouse, because why would anyone want to bring back the echo of a murderous psychopath? Rendell used it to at least bring back his mom so he could talk to her again. Then I realized maybe Rendell, or someone else, brought back Dodge for the same reason, hoping to bring back the echo of his old self before he was possessed. Obviously, it didn't quite work.
In Clockworks, the reason the boiler isn't working despite multiple plumber inspections is that Bode is desperately trying to communicate in ghost form the only way he knows how.
