But that is nothing special, that is just Harry being Harry. Peace talks will show that Harry is still a member with all the rights and obligations that brings.
Um what. That was exactly my point. Harry being Harry he's been calling the council out for ages and will undoubtedly continue to do so for ages more. There's nothing special about Harry doing that and there never will be. Yes maybe someday circumstances will conspire to give Harry the whip hand and change how the council works, but Harry's not going to treat them any different just because he's got the whip hand, thats not how Harry works. He'll stand there and spit in the eye of gods, faires queens, vampire,s angles, (fallen or otherwise), and plain old vanilla mortals no matter what his relative position against them. Thats how Harry rolls.
Molly is not human anymore, according to the councils definition of human. That will place her outside the councils jurisdiction.
More to the point so long as it doesn't interfere with the purpose of her court Mab mostly isn't going to give a monkey's about what anyone does to any of her people. The Winter Knight Mantle changes hands reguarly, getting a new knight would put a hiccup in Mab's work, but an easily smoothed one. Having to replace the junior queen would be a major disruption, and that makes it a direct attack on the courts purpose. Mab is really going to care about that, zand she's winter fae, her response to any kind of threat to her purpose is going to be to kill it as fast and hard as possibble.
