On summoning and sending. There is a discussion between Bob and Harry about how fetches move back and forth. When Maeve summons there is a tell. The temperature drops 40 degrees. This happens in the Cantina scene in Summer Knight
Sudden blue light gathered around her fingers, and the temperature in the room dropped by about forty degrees. She spoke again, and flicked her wrist, sending glowing motes of azure flickering toward Slate.
and now Proven Guilty.
The temperature had dropped maybe forty degrees in the space of a minute.
As I did, the air temperature plummeted, sending the hotel’s climate from near-sauna to near-freezing in a handful of seconds.
It's a sign of Maeve not using her magic effectively. When the fetches attack Pell in the bathroom Rawlings just outside the door notices nothing like that. And as a bonus no one is killed. But that event starts Dresden down the road to discovering Molly.
Sandra Marling is the player in the center who brings all the kids together and suggests to Molly that fear could control her friends. Sandra meets them because Molly has gotten in trouble with the authorities and is in conflict with her family and Marling is volunteering with at risk kids.
Early in the book Harry suggests that the best way stop warlocks before they become one, is to try and find them.
The best solution is prevention. Find the kids displaying serious talent and teach them better from the get-go. But the world population has grown so much in the past century that the White Council can’t possibly identify and reach them all.
Given in the Dresden files that magic is a myth to the public these kids would tend to be like Charity and Molly and find themselves in the juvenile justice system. The BC seems to be looking in the same way that the Formor are seeking minor talents.
Why do I think LC and the Outer Gates might be related. In White Knight when Harry follows Grey Cloak and is sensed by Cowl and attacked,
Cowl held up a miniature hand for silence, a gesture that looked, somehow, stiff and pained. Then his hood panned around the room.
The figure's gaze met mine, and hit me like a literal, physical blow, a swift jab in the chest.
"He is there!" Cowl snarled. The misty figure turned to face me and lifted both hands.
the scene mirrors the scene in Small Favor when Mab uses the snow scene to show the Denarian's taking Marcone, including Gard blocking Mab's vision.
Then Gard’s head snapped up, looking directly at where Mab currently stood, as if the little snow sculpture could somehow see the titanic form of the Winter Queen looking down upon her. Gard reached into her suit pocket, drew out what looked like a slender wooden box, the kind that really high-end pen sets come in sometimes, and took a small, rectangular plaque of some kind from the box. She lifted it, facing Mab again, and snapped the little plaque in her fingers.
The entire snow sculpture collapsed on itself and was gone.
“They saw the hidden camera,” I muttered
In one of the short stories Luccio say that the white Council doesn't have a satellite to detect Black Magic but that Rashid seems to be very good at it. This it turns out is Rashid's job at the Gate. And he tells Harry that the eye has many functions.
The thesis is then that the whole thing was an attempt to get Harry out of the way by putting him at odds with the White Council using Molly as a stalking goat. Uriel, unnamed until another book, moves Michael out of the way. Rashid starts Harry looking and Mab shows him where to look.
The third attack is meant to be big and draw the Council in, Madrigal is window dressing whose killing would make sure the Council wouldn't miss it. With no warning Harry would only find at the trial that Molly was the warlock. Leaving him no choice but to go down swinging.
The events at Arctis Tor are more difficult to explain but basically they reveal why Mab didn't retaliate. She isn't sure if Summer is behind the plot. But it tells Harry that the Denarian's are involved. and it keeps Harry out of Chicago why the events involving Michael and Eb play out. And finally it is clear that Rashid is helping Harry delay as his allies approach at Molly's trial.
