There were way to many variables with too many available paths to being seriously up the creek for the CI scenario to have been micromanaged. MAYBE if we had seen Lea whisper to Harry that turning Susan and sacrificing her was tha answer I could by into your theory, but Harry came up with it all on his own that we could see. An no one, anywhere, wants to leave any plan up to Harry's bolshevik muppet thinking bringing him to the right conclusion.
Read the conversations that Harry had with Odin, Mab/Lea and Uriel again. They don't
quite draw him a chart but close... Odin at least was practically hammering him over the head with "See, bloodline curse will follow the bloodline up, remember this, it's important, and did I mention that all Red Court vamps are family-as-in-related-by-blood, geddit? Get what I'm saying?" Susan wasn't going to randomly die in the battle either, because Lea gave her magical protections that made her completely undetectable and she had Amorrachius to boot. Sanya conveniently appeared after Harry was injured, not ten seconds before when he could have stopped it from happening. Both Odin and Uriel directed Harry towards becoming the Winter Knight. And from where exactly did the idea to sacrifice Susan come into Harry's head, anyway? Mab
was whispering in his mind during that battle.
I agree that those three COULD have known, but I doubt that all three DID know. In fact, I'd bet that the WG and Lea/MAB did know. Odin - maybe after Harry's visit. But enough for them to micromanage the events in Changes ... I find that doubtful.
There's no doubt that they knew. They all mention Maggie before Harry himself brings her up, and Odin is the very person who volunteers the info about the bloodline curse and Chichen Itza.
ETA: And on top of all this we know for a fact that Mab's highest ranking servant, Lea, and Odin were working together to bring the Grey Council to CI. There had to be coordination and planning going on.
Oh? I'm sure it wasn't an accident.
Same here.
