Also, as far as foreshadowing. Harry recovered from death in Arctis Tor for weeks. Once Mab started trying to murder him daily for a set numbers of days, 60-70-ish. That seems innocuous yet vaguely important, the number of days, or the progress he made in that time. Of course, as a final product after that "training" could never compare to what he'd have managed to train up to on his own. Death is the great motivator. There were only a few examples given to us as what types of encounters he faced. But I would assume that Mab what throw seemingly random death at him, that wasn't really random at all. Events coordinated to force him to use this magic over that, to use brains over brawn, to use environment over skills. Harry is now on a level that I believe he absolutely could not achieve on his own.
All because of a deal. I think that another deal may come up.
Fae love games and bargains. Who's to say Mab won't be offered a deal that's too sweet to pass up? The trade however would be giving up her knight? Harry's already an "indentured servant", and historically indentured servants contracts were purchased en masse in some cases.
I'd love to see Odin buy out Mab's hold on Harry. Have Harry swear fealty to Odin. Or even have Odin nullify the deal altogether, just to have Harry owe him one. Or even Chauncey come back and trade Harry with Hitler... Thoughts?

...I had forgotten that. And after that is checked off, he calls in a favor from Mab that was possibly blocked before by RCV? Maybe the break-in was also on this check list? That would suck and be completely par for the course if Harry was inadvertently helping the nickelheads achieve their goals. the Charlie Brown of urban fantasy indeed..

well I agree but for a different reason. Yes, he has said, it was Mab, Lash, or kemmler. But only as far as the options that had the power to help him, not because those were the ones that had beef with RCV.

I did post this in another thread, but still seems relevant here as well. Let's call one of the GC as a member of the Denarius. We, of course, don't know the extent of the Denarius' plans or even all of their enemies. Who's to say they didn't have a reason to get back at the Red Court? And of course the theory I floated in the other thread.

I could see that. Our Harry will eventually break the time law. And hilarity will ensue. We have to assume that if there was a split decision, and the alternate Harry in that bubble still thinks along the same lines, just with a more pessimistic view, we must also assume that this altHarry will break the time law as well. Possibly even more if he's taken out those who would come after him for it. (WC) So the propagation of his alt-ness would ripple even into the past that presumably both worlds shared. And by shared I don't mean interacting, just that they were they same until that split.
Though, the theories about Cowl being Harry fit better if he's the altHarry.
