Like with politicians..

Yes and no.

Politicians say weasel words and half-truths all the time because its better PR-wise so when they don't follow through. They can claim that their words were misunderstood.

The Fae hedge their words so that they can fulfill their oaths in the way most advantageous to them. They always keep their promises, but opinions may differ on what the promise actually was.

But was it really?  Interesting that it was a shot to the heart and not the head, death wasn't instant was it? That he fell into ice cold water that would immediately begin to cool his body and slow things down, that he just happened to fall into Mab's waiting arms. If he had fallen onto the deck, he would have quickly bled out.  Harry was never all dead, he was mostly dead, which is slightly alive. Uriel wanted to teach Harry a lesson, and Mab felt she had no choice but to go along knowing it was a risk because "death is a spectrum".  Ivy was pissed because Harry would think of doing such a thing, and more pissed at Kincaid because he'd go along with it.  It is my opinion that both Mab and Uriel anticipated what Harry was going to do and acted accordingly.

Ivy forced Kincaid to make a chest shot and not a headshot. If Kincaid had done it with a headshot Harry would be DEAD dead. There wouldn't have been enough for Mab to save.

Exactly, before she was infected she was 100% vanilla human, if she had talent it was of the ordinary kind like Butters when we first meet him..

Yes, but we are led to believe by the books that Susan didn't become pregnant until after she was infected. So Maggie is the child of a wizard and a quasi-ramp. If she has any magical potential, then Chichen Itza may have activated it early.

Sadly, I think this is true of every character in the series that isn't a present or former Knight of the Cross.

Why give Harry a way out? If Aurora and Elaine are both nemfected?

And if Aurura died where did her Nemfection go? Not Lily, Fix? Toot? Aurora died by Harry’s hand he was holding her while she died. Maeve was killed by suicide and her infection passed on. Is that the difference? Harry in killing the host kills the Nemfection?

Maeve died by Murphy putting a bullet through her face on Halloween. And her Nemfection didn't pass on. Justine was already controlled at the time according to Nemesis' own words.

“How long?” I asked. “How long have you been in Justine?”
Justine waved the steel bar in a vague gesture. “Mortal time is such a limited concept. A few years. Ever since she became close to Lara.”

I've never thought that they can't affect the physical world. We've had plenty of evidence of that. I just think that they can't form ectoplasmic bodies.

We are told in Skin Game Goodnan Grey pulls in ectoplasm from the Never to increase his mad to that say if a horse. The principle for Bob to create an ectoplasmic body would be identical.

No idea how a shapechanger gets rid of mass though I do note that both LTW and River retained their mass in shapechanging in PT and BG, so I suspect Jim hasn’t figured a convincing explanation either in his own universes rules.

One way would be to convert the mass to energy, but then you need to store that energy and then convert it back into mass, basically teleportation. BG of course contained foreshadowing Harry aging shape shifting and teleportation abilities in the future.

Notice that Goodman Grey is a corporeal being. Bob is a spirit being. We know that he and Evil Bob can both form bodies once they are in the Never-Never, but not once do they do it in reality.

I think manifesting a body requires a link to reality that only corporeal beings innately possess. Ghosts possess the link because they were once alive and summoned beings get it thru their summoner. Spirits just don't have the required innate link.

Even the greater powers are limited in this way. The Fallen need their Coins and hosts and even Uriel only became solid after investing his abilities in Michael.

And it has to be this way. Otherwise, some minor wizard/warlock/witch would accidentally open a portal to the Never-Never and things would come pouring out.

I don't believe he can.

I don't think any spirits except for ghosts have ever formed an ectoplasmic body on their own. And even the ghosts need to be "insane." Every other entity that has been seen so far, that has formed an ectoplasmic body was either summoned or is still corporeal and uses the ectoplasm for shape changing purposes.

It makes sense though. Otherwise, the world would be a far more dangerous place.
