About MM, what if Harry comes back with MM-Harry and MM-Murphy. She stays here with him and the other one marries Lara and then finds a way back home. So, no vows for our Harry.

I have my doubts that he's going to be coming back with anyone. Given that MM-Harry is likely wholly dark side, it's more probable, I think, that normal Harry is going to end up having to kill him ... which will definitely give him some more issues. (Does that count as suicide?) And considering Grave Peril was when the Nightmare really tore into Murphy & they were at the height of distrust as a result, I can't see MM-Murphy becoming an ally. Time will tell, I suppose.

Later, however, there's this bit:

Then she stepped back and inclined her head slightly to Ebenezar. "Excuse me. I must coordinate with my sister's forces. Brief him on the plan, if you please."

I suspect it was just that.

He's a Knight who operates on the principle of "When I need something, it happens." Seems pretty simple. Remember how Michael just opened the door and Father Forthill was standing there, about to knock? Why can't Sanya inexplicably discover a crashed gang-banger's car that happens to have an AK in the back?

Harry knew about the chupacabra, he did not know Molly attacked him or why.

Yeah, that's how I read it as well. If you read their interactions as Carlos thinking Harry knows that Molly went gonzo on him due to the Mantle, and Harry not actually knowing about that, it sheds a lot of light on why Carlos is frustrated at him because it does seem like Dresden is threatening him and being an utter dick about it to boot...

It seems to me that Mab has probably more than one or two reasons for wanting to marry Harry to Lara.

I'd argue, given what we've seen in recent books, that Mab always tries to protect Harry (despite Harry's objections that she would only care for a Knight who can protect himself, she's been doing a lot to help him or prevent him from doing mistakes). So I assume that her main reason for her to make them marry is to protect Harry. She wanted it to happen right away. Why? Most people thought it was to torture Harry, but what had just happened? Harry had just been kicked off the WC, so he's basically defenseless. An alliance/marriage with Lara would mean one thing to Harry's potential enemies: if you attack him, you attack the WCV. Mab cannot protect her Knight openly, or it would make him look weak, but by giving him an ally who is basically a Chief of State of an Accorded Nation, attacking Harry would mean a lot more to potential random enemies (it's not gonna stop Mavra or some crazies/really powerful enemies, but it can stop others).

Second, Mab has to repay the favors she owes to Lara, and from her point of view, there's no reason not to strengthen Winter's position by making a more permanent and reliable ally out of the WCV, especially since Lara is such a good political player.

Third, the marriage is meant to piss off Molly, and to basically tell her to forget her human emotions and to start acting like a Queen of Winter. Mab said she was lacking and too dangerous to become Mab right now. Considering what we've seen about Mab, it's probably about being "cold" enough to put your feelings aside and do what's necessary. And Molly can't say no to Harry and will always run to help him, even if it means somewhat endangering her duties as a Winter Queen or exhausting herself and leaving her vulnerable.

Fourth, it widens the gap between Harry and the WC. From what we've seen at the end of BG, the Accorded Nations don't trust the WC, or they would have invited them to their private talks. One-Eye and Mab at least know that they're probably at least somewhat directed by either Nemesis or the Black Council (or both). It also protects Harry from the WC, because basically killing Harry would mean waging war on two Accorded Nations, which even the WC might be reluctant to do, especially in their weakened state.

Fifth, it protects Harry from Lara. She might be a "good guy" nowadays, but she still puts her interests or that of her family/Court first. Making Harry part of that family would make her less likely to kill him for political reasons.

Also, I agree that Lara totally knew what she was asking. She's completely in femme fatale falling for the detective mode right now. Freydis told us as much in PT.

This is very well phrased and tracks with my thinking. Plus, it'll (hopefully) give us a dumpster fire for a wedding that will be absolutely hysterical to read. "The wedding cake was on fire and it was my grandfather's fault."

Oh. Did you mean "White Court" instead of Council? I personally think that pretty much everyone knows that Daddy Raith is not in charge anymore ...

I did not like the Librarians introduction at all. Specially because we don't need more factions.

I actually think they were long overdue. Looking at it, the notion that the American federal government - or heck, any national government - just sitting back and not getting involved with the supernatural in any capacity is hard to swallow. They sit back and allow the White Council to dictate terms which, admittedly, has several centuries of capabilities on them, but still. There is no way, IMO, that individual national governments would not try and get involved in some way (whether that means fighting the supernatural, recruiting it, trying to suborn it, or even join it…) So there long needed to be some sort of organization in place that keeps trying to get Accorded Nation status but keeps falling short for some reason...

(In a Dresden Files RPG that I was running, I was about to introduce an overwatch organization called AEGIS (intentionally making a joke about SHIELD there) which was run by an Athena Grey who would naturally turn out to be the Athena down the road... so I am a little biased toward them showing up, though. )
