What happened with 3?
1, 2 we don't know if he is going to be the Warden after BG and if he will be keeping the weapons.
The others, I don't know how much will be revealed, but we know that after BG there will be still a White Council and Harry will still be a member. We also know he is still the WK and Winter good graces. What else? Well, Mab, Molly, Vadderung, Sarissa, Michael, Maggie and Mouse are alive. Harry had to say "too many goodbyes" and I can stop hurting thinking on that. (Oh, please, let Mister be well)
