I've been rereading Dead Beat, and one thing really jumped out...
When Harry is helpless at the feet of Cassius/Liver Spots, expecting to be tortured to death, he thinks about Shiro and decides that his best tactic is to stall in hopes of divine intervention, probably in the form of one of the Knights. He figures that as a former Denarian Cassius has a karmic connection to the Knights, and also the total depravity of the necromancers would tend to attract disapproving heavenly attention. In Harry's own words, "In my own experience, I had noticed that when something truly, deeply evil arose, one of the Knights tended to show up."
This goes on for several paragraphs. Butcher makes it kind of a big deal.
Here's the thing ... when Harry is rescued a couple pages later it's not Michael or Sanya who saves him ... but Waldo Butters (ably assisted by Mouse) performing what is probably the first physically heroic act of his life ...
So what I'm wondering is ... is this just a cool coincidence, or was Butcher actually foreshadowing Butters destiny as a Knight a full eight books before his actual recruitment?

Sorry if this has been thoroughly hashed over previously. I'm new here.
