“You remember the Red Court’s attack last year,” he said. “That they called up Outsiders and assaulted us within the realm of Faerie itself.”
“Bad move, so I’ve heard. The Faeries are going to take it out of their hides.”
“So we all thought,” the old man said. “In fact, Summer declared war upon the Red Court and began preliminary assaults on them. But Winter hasn’t responded—and Summer hasn’t done much more than secure its borders.”
“Queen Mab didn’t declare war?”
“No.”
I frowned. “Never thought she’d pass up the chance. She’s all about carnage and bloodshed.”
At least consider the possibility that Mab didn't send the fetches or kidnap Molly. That the fetches may be there to draw attention to the Black magic in Chicago, goaded by the Scarecrow who might be controlled by the Adversary. Consider the outcomes if the Council executes Molly or if she is Killed at Arctis Tor. This is a loss to either the Council or Mab. Depending on how Molly dies.
Bob's theory on time travel is misdirection, if I'm in the same ballpark with the story. Mab sends the Gatekeeper. It's only in Cold Days that you find how close the Gatekeeper is to Mab.
Madrigal says that he has been scheduled for a year. Don't you find it convenient that it all goes down when he is in town? And then the Jinn gets whacked by the Scarecrow, who has no reason to be there. Certainly Harry thought it strange. It becomes more understandable in White Knight.
And why attack Arctis Tor at all? Everyone in Faerie would have done exactly like they did when Harry used Summer Fire. There's more to it but it's late.
Mab is running multiple games countering the Adversary.
