Yeah pretty much. Assuming they somehow survived the Bloodline Curse, and then Goblin 'Hospitality' (which is admittedly possible)... The Eebs are a couple of two-bit loser cowards.
...
They were barely willing to fight non-Winter Knight Harry, with an army of minions and the full backing of the Red King. I doubt you could get them on the same Continent as him now.

Right, but that isn't the same as not being dangerous. The danger they pose just won't take the form of coming at Harry in a straight line and promptly getting their asses kicked.

They're perfectly capable of putting a price on Harry's head for contractors in the same general league as Kincaid or Goodman Grey from a continent away, for example.

Being smart and cautious where their own safety is concerned, though, I'd expect them to just wait for time to take care of Harry for them. At the end of the day, they're immortal and he isn't.

Because Mab doesn't have free will.  She wanted to respond to the Reds but couldn't.

Wasn't the Reds' trespass against Summer though? And Winter was only massing on the borders out of fear that Summer would hit them while their Knight was out of action rather than pay the Reds back?

Not having free will like a mortal is one thing, but that seems really extreme in the direction of troop movements being governed by instinct rather than conscious strategy. Besides, I don't think Lily would have found Mab's posture so inexplicable if it was a matter of Winter must do this in circumstances where they're disadvantaged by the margin of a Knight. Each side seems to have a pretty good sense of what's going to be driving the other in a given situation.

I think Mab had her troops far from Arctic Tor as a trap to figure out who else the infection had spread to from Lea, and / or restrict Maeve's ability to spread it around the army.

Could just be Peabody, but I don't think so.  I don't remember Harry noticing that Peabody's voice had any peculiar characteristics, just that he came off as an officious little twit.

Plus, a name like "Peabody" is pretty much as native-English-speaker as it gets.

It could have been that one, yeah. In the one I'm thinking of, he definitely talked about the name of the assistant Bianca killed changing from SF to GP as an example of an oversight, if that rings a bell for anyone else who can find it.

I remember thinking one of the shorts referenced a main novel later than the ones Jim had placed it between in the foreword.

That was the one where Harry was telling the Warden cadets a story, right?  I'd guess the earlier timeline is when the events actually happened, and the latter is when Harry was narrating them.

One must wonder though what the structures on the island with all those nifty runes  from some ancient era were doing while the ice went over the top.  Just maybe those damaged buildings are the source of the limp.
It all makes you wonder exactly how long ago those building were put into place by Merlin, as played by Alec Guinness.  Apparently the last glaciers went over that area about 35,000 years ago.  Or 34,000 Years BM(Before Mab)

Well, Merlin must have gone some distance into the past to lay the spell for the prison in five different times. But the stone buildings may not have been created at the earliest point he visited the island.

For one thing, even if he quarried and assembled the stones by magic, the fishing town that occupied the island somewhere around 1900 probably would have noticed something out of place if the architecture of the lighthouse was characteristically pre-medieval European from Merlin's native time, and showed obvious centuries worth of wear. Chances are Merlin convinced some settlers to build the structures on one of his forward excursions through time, and dropped his own enchantments on top.

In the first person storytelling mode we're experiencing, it makes sense that Harry is reluctant to divulge every detail of his last confrontation with his ward and mentor but when can we expect to see it? Is this the big choice that Harry makes in the "Mirror, Mirror" book? To follow Justin down the left hand path? Or later to succumb to the wolf belt in "Fool Moon?"

Jim's plot tease for MM was that the divergence started with the "big choice at the end of Grave Peril".

The readers have, to some extent, disagreed on exactly which big choice that was. The leading candidates were whether to tell Susan he loved her, whether to accept Ortega and Bianca's deal to give up Susan in exchange for peace, whether to fight or flea at Bianca's masquerade (which is stretching the definition of 'end' of the book since it's only about the 2/3 mark) or possibly whether to trust Thomas when he returns Amoracchius.

That last seems like less of an obvious big choice, but I've argued the case that it's potentially at least as consequential in terms of setting Harry's path afterward as the others.

As for a full flashback of Harry roasting Justin, though, no you haven't missed one. JB hasn't detailed that, and there's probably some reason. I'm hoping it's not a "Justin faked his death" reveal, though.

An interesting argument. Certainly possible at any rate. I don't remember that particular WOJ about her identity being someone that will hurt Harry but I am not doubting it either. Makes much more sense though if Kumori is Elaine, particularly in the context on Cowl being Justin.

I recall that one too. Someone asked in a Q&A if Kumori was D.E.D. from the blast when the Darkhallow backfired like Harry and Bob originally assumed, and Jim's answer was something along the lines of 'Why kill off a character when I can reuse her and have her identity cause Harry pain?'.

It's probably actually the biggest single piece of evidence for narrowing down Kumori's identity. There are less than a dozen magically talented female characters who it would personally hurt Harry to find out were working for the Circle.

Elaine
Faith Astor*
Jenny Sells*
Kim Delaney brought back by Cowl's necromancy (which would actually rather neatly explain her motivation to end death, her reluctance to strike at Harry, and her certainty she couldn't escape Cowl if she flipped on him ... I regard it as unlikely, but I can't see a reason it's impossible)
Maggie Sr**
Maggie Jr**
Molly**
Luccio**

* If they even developed wizard-level talents later in life
** In case of time travel / alt universe shenanigans that would cheapen the identity reveal anyway


As for Cowl, most of your points favouring him as Justin could also apply to the case for him being Simon. If the fake death curse was explosive enough, it might have been natural to assume his body was totally obliterated.
