I think that, when it comes down to discouraging dangerous enemies from doing evil things to the people you love, it makes little difference whether the person is related to you or not.

Whether Ebenezar raised Harry as his grandson, or raised him as an adopted son, doesn't mean that he wouldn't have essentially gone through the exact situations and scenarios that Eb claims to have been trying to avoid.  If Eb was trying to keep Harry away from attention and dangerous people who would have had reason to either murder, kidnap, or enslave him, it wouldn't matter if it was adopted or not.

But Klaus employs much of his magic through toys and objects, and Cowl showed no sign of that.

Are there any Warden-level wizards that have made appearances and are not firmly in the "good guy" category?

Is there really ANYONE who is firmly in the "good guy" category?  I mean, literally, all Warden Chandler would have had to do was intercept the letter intended for Dresden from Anastasia in Changes and substitute one of his own, and suddenly Dresden not only think's he's got Ana's full trust, but all the readers think he's an A-OK guy, too.

Thirded.  I'm not sure who said it first here, but narratively, it really is time for the wise old mentor to die.

Here's hoping that he and Thomas not only learn about each other, but have some sort of reconciliation, before the end.

Yes, but unless Dan Brown was really onto something, he didnt have any offspring.

Most likely he's from the line of David. After all, Jewish tradition highly looked down on marrying outside of God's chosen people. By now, they're probably ALL related to David in some way or another.

Here's an interesting fiction trope that I hope gets used.

All those outsiders, struggling so hard to burst through the Outer Gates, and to leave wherever they're coming from and enter our reality.

What are they running from, and why are they so willing to die by the billions to escape it?

Yup.  This is one of the things that I believe - that either Malcolm Dresden works for Uriel in Chicago Between (or another office), or he works for a similar organization that labors to ensure free will and balanced scales that we just haven't heard of yet.  The exchange in Dead Beat is just altogether too similar of what we see in Ghost Story to be anything but.

The only real argument I've heard against this is that Malcolm Dresden was a good man, and that Between isn't for people who are ready to Move On.  But I think that it would be painting Between with a little to broad of a brush to just up and call it Purgatory, and that the only thing that could keep a mortal man between is not being either good or bad enough for a northbound or southbound train.

Besides, there's a chance that Papa Dresden had an inkling of what his son may have to face one day, and the last thing he ever wanted him to do was face it alone.  Something like that, I could imagine, could keep a person from moving on.

Cozarkain - I get the conundrum you're talking about, but I think you might not be giving the idea that Mab's lie is a lie of omission a fair enough shake.  Faeries cannot speak lies; however, they do nothing but lie through omission.

In addition, take into account the comment to which Uriel (because it is Uriel; he's not about to go and rope some lower being into lying for him, especially considering the circumstance with Collin Murphy) responds to:

"I have his oath, ancient one. What he has given is mine by right and you may not gainsay it. He is mine to shape as i please."

She's saying this for Harry to hear, but she's not saying it to Harry.  From the perspective that the quote is being said, it is absolutely true.  Demonreach cannot do anything to stop what she does; she has the right, not Harry, to work her will on him.  The fact that she never says "As long as he doesn't put up an epic amount of will to counteract, which almost no Winter Knight has ever done" doesn't really need to be said, as Mab's statement is truthful to the letter of the word.

Yet Harry's understanding of Mab's words is not truthful.  The Fae are deceitful, manipulative creatures, and Mab's omission here is critical.  And while a lie of omission is permissible to the Fae, it is still a lie to an Archangel of the Lord.  Therefore, Uriel is perfectly correct in stating "Lies," rather than "False" or something else.

Hmm...  I dunno, I'm skeptical.  Jim likes his foreshadowing and his various pieces of Chekov's artillery.  I mean, we got at least two different mentions of Wizard Peabody before he was ever relevant to the story.  So I really, really think that we must've seen Cowl's alter-ego throughout the books, in one form or another.

The only wizard of the White Council who I can think who's appeared several times but doesn't have a name is Lucky, the poor sod who Mab almost killed when asking for passage through Winter in Summer Knight.  And I really, really don't think that Cowl is Lucky the Wizard.  I think there's a higher chance of him being the annoying mailman from chapter 1 of Storm Front.  That, at least, follows Scooby-Doo tradition.
