I've been reading this thread. A few comments.
When Namshiel gets control of Marcone it will be by using Marcone's little secret shame in a coma.
I thought the same. I don't know exactly how, but that girl is involved. Also, Marcone won't be subjugated by the Fallen. They will work as equal partners or Marcone will dominate him. But I think sometime in the future, Marcone will ask Harry and the KotC for help to get rid of it. I don't know. I just want to see Marcone asking Harry for help
Another question I have is: what's up with the conjuritis? It is over by the end of the book? Does it has a meaning before just a random sickness with side effects? I thought it meant that Harry had got it from Maggie, who would be revealed as a witch. But as nothing is mentioned in the book or, six months later, in CS, I am not sure now.
Last thing (I mentioned it in a thread about Justine), will Nemesis carry the baby? Will they be born between books? What utility will the baby have for Nemesis? A host?
