I was going through Battle Ground and realized something:
The top tier of Dresden Files is pretty weak.
Mab, Titania, Odin, all these immortals all suck Ethniu's toes when it comes to the wire (which kinda begs the question as to why the Fomor are part of the Accords and not the unquestionable top dog of the world when apparently their leader could take everybody else's leaders, simultaneously, in a cage match).
Ethniu's big bad laser, which can disintegrate Uriel's physical form if he doesn't do the genius move of blocking or dodging it, has an upper limit of destroying a few buildings and maybe, at most, a city block (which somehow is enough to weaken reality????)
Mab (even accounting for it being Midsummer and so at her weakest) blocks said laser with raw power and is down out of exhaustion. I guess the Queen of Winter can block a city block's worth of destruction, which really isn't all that impressive from what I'd imagined Mab should've been capable of.
Even her compatriots, when they've disarmed Ethniu and weakened her with a whole lotta rain, just went down like a buncha mooks against Ethniu. Literally folded like a wet paper towel. Titania at the height of her power is nothing against Ethniu (who again, despite having the most motivation to cause mass destruction throughout the entire book, is only ever seen blasting, like a couple of buildings at a time with the Eye, which she didn't have when she dropped the Erlking, Odin, and Titania like a gaggle of redheaded stepchildren)
Literally, this scene has the most destruction we've seen on screen, from people with no motivation to hold back, by people we're told could take on the entire White Council (a single one of which apparently caused the Tunguska Event). And they all suck. Apparently, the power to beat a handful of immortals and warp reality itself has the same firepower as, like, 10 or 20 or 50 tons of TNT. (Or maybe even less than that, given again, Ethniu handed everybody's asses to them without the Eye, one shot of which was enough to drop Mab)
In retrospect, given how weak a showing all these immortals had, I wouldn't be surprised if Essence 3 Molly could straight-up pimpslap Mab or Titania or anybody worth a shit on her lonesome. If you thought Molly has resource issues with running low on Essence, Mab clearly has much bigger problems with running out of juice mid-fight (seriously, one not even city-buster-level laser is enough to take her out????). It's not like Odin or the Erlking or even Mab could've done anything to Ethniu if she wanted something and they were by themselves, or even all together as was shown in Battle Ground. At a certain level of power (not even that high), the leaders of the supernatural factions kind of have to let you do as you will unless you're gunning for their lives and they can't run, and Molly is very quickly approaching that level. Sad, really, given Molly isn't even that powerful a Celestial Exalt, but man Battle Ground brought down the bar in terms of how powerful the heavyweights of the supernatural world really are (barring Ethniu who apparently is the only one who lifts I guess). I guess they could try and threaten Molly's friends and family, but that runs into the fact that if Molly were in a room with Mab, Titania, the Erlking, and Odin, one of them can perfectly defend against setting off a snuck-in nuke, while everybody else is going to just die.
Seriously, even disregarding Molly using her Crown to ask for what are any random immortal's weaknesses and publishing it on the internet, Molly is still going to quickly approach Ethniu-levels of "I can do what I want because everybody else sucks"
), there's nothing stopping Molly from strolling into the Winter Court and making Mab swear a laundry list of concessions. What's Mab gonna do, not swear and get a first-hand taste of a human SUN? Once you have enough power, you don't have problems with your enemies. You have dead enemies and people who try not to be a problem for you.
