Sanity check.  Saying somebody has a good soul is not the same as saying that they were soul gazed.  Eb may have looked at him with his sight or he may just have observed Malcolm as he raised Harry. If Malcolm was soul gazed by Eb then Malcolm would have seen Eb.  Nothing in the text mentioned that Malcolm had ever met Eb.

Except Eb seemed to know Malcolm pretty well.. page 299 Blood Rites paperback

"She met your father.  A man.  A mortal, without powers, without influence, without resources.  But a man with a good soul, like few I have ever seen.

Confirmed by Eb in this passage, Malcolm was an ordinary human, not a scion of an angel or anything else.  Also while if you want to split hairs, one could claim that when Eb says, a man with a good soul, like few I have ever seen. He means he saw him and thought he was a good man, but really? I think when Eb says, "a good soul, like few I have ever seen. Yeah, Eb did a soul gaze with him and saw his soul.. It makes sense that he would, after all his only daughter was taking up with this man, and seemed changed by him.

He didn’t even try the weak pretence of “present company excepted”. Wizard’s have terrible social skills, it’s not just Harry.

Eb hadn’t ever met Harry other than in his capacity of his Master/mentor, nothing really to hide, and that is Eb’s fault due to his theory of childraising. They had no other connection. Bad Eb.

He really only started his grandfatherly relationship with Harry after the soulgaze, probably when he realised he wouldn’t have to execute him.

I suspect during Next Book the existence of Maggie becomes widely known amongst the Supernatural community, and Harry basically says:-

“Come for me, not my daughter if you have a beef with me.”

“The Red Court went for my daughter, kidnapped and brutalised her. I rendered them extinct. All of them.”

“Nicodemus Archelone threatened my daughter, I gave him the very worst day in his very long life, and I haven’t finished with him yet and I WILL kill him, because I can.”

“The Titan tried to kill my daughter. Ask her how that worked out. If you can find her. Please try to find her.”

“Mortal or  immortal, threaten my daughter and it’s the last thing you will ever do.”

His views on the subject are diametrically opposed to Eb’s, so no wonder it didn’t come out in the soulgaze.

None of that has any baring on Eb's opinion of Malcolm's soul, nor does is it any reflection of what Eb thought of his grandson at the time of their soul gaze.  Harry was a sixteen year old alienated and angry kid who had just killed his adopted father and nearly lost his head for it.  At the time of the soul gaze Eb was under orders to kill his grandson if he saw anything overly off.  He didn't.. Now I guess it depends on how one compares the souls of teenagers driven by hormones to adults who are driven by other factors.  So it is really hard to make any comparison in my opinion.  I think Harry was happy to hear that Eb's opinion of his father mirrors his own memories as a six year old of his beloved father.  I don't see Harry or anyone else in his place upon hearing this, demanding, "well,what about me? You soul gazed me too.."  Nor has Harry ever thought of himself as some kind of saint, so the idea that Eb might think higher of his father than himself, wouldn't bother him.  Also I might add, everyone who knows Harry and knew his father says he has his father's good heart, that should be enough for any good son.

Eb has probably soul-gazed Listens to the Wind though, which would set a high standard for Malcolm. He soul-gazed Harry, so telling Harry that Malcolm was the best is an unintentional dig at Harry. Bad Eb.

All that means of all the people Eb has soul gazed up until that point, and I imagine that is a lot of people.  It doesn't mean Malcolm's soul was the best out there, only of those Eb has ever soul gazed.  Harry wouldn't see it as a dig at him, he knows the state his soul was in when they had their gaze.  He also doesn't see it as some kind of goodness contest between Malcolm and himself.

Eb did soul gaze Malcolm, in Blood Rite he told Harry that he was the finest or best soul he'd ever seen.  With plain old vanilla mortals that is just a saying, but Eb is a wizard so it takes on a different meaning.  If Malcolm was a scion of something else, Eb would know.

We simply do not have all the information to say something or other definitive about Mab or her motives. Look at how she was presented originally as a Evil Faerie Queen as opposed to the more nuanced representations in the later books, as the great defender of humanity. I think that process has yet reached its ultimate end, and the likelihood is that the end result isn’t going to be black and white. Mab is going to turn out to be a VERY complex character with everything we have seen to date only parts of that character.

Basically You are probably both wrong, or probably both right.

I've never thought that Mab was evil.  Why?  Because Winter is a force of Nature, Winter can be cruel but that doesn't make it evil, and without it, the world would be worse off.

Harry at first sees her as evil because that is how he perceives his godmother, Lea.  Why? Difference of opinion on how to keep him safe, he fears her and by extension everything else about the Winter Court.

As Harry gets to know Mab and understand her and Lea better, he comes to realize that she is indeed a complicated creature, perhaps even a likable one, once he comes to understand her better.

Count the pieces on the chessboard. With an eye to the balance of the courts. Butcher feeds you there answer. 

He has Harry present a rationale that you can compare against what really happens later.

Maeve is selling the idea that Mab is Nemfected to the Summer Lady. The second paragraph is Maeve's con. The first paragraph is for contrast when Harry throws Summer Fire at Winters Wellspring. Mab tells him why Slate lives in another book.

But was it a con?  I don't think it was, you forget that we saw Mab with the Knife in her belt.  She isn't immune to the effects of the Knife anymore than Lea or Maeve herself were.  I think Mab realized it sooner than Lea did and got her monoclono antibodies before the infection could fully take hold, thus she was able, barely to direct her defense.  However Maeve didn't know, by this time she was full blown bat shit and betrayed her mother.

As of Dead Beat when the conversation with Malcolm takes places he still has the sigil doesn't he? His hand is burnt in Blood Rites.

Yes, but he got that because he picked up the coin, but he never accepted the coin.  As in fully embracing it, taking it into himself, thus becoming a Denarian. The coin is physically taken into the body in some way, remember when a Denarian dies the coin sort of falls from the body.  Or as in Sanya's case thrown away in rejection. One of Lash's last acts in White Night was to save Harry by trying to get him to accept the coin,when Harry refused it, she sacrificed herself for him.. Once she did that the sigil was gone from his hand. Lasciel had marked Harry, because he touched her coin, but she never got him.  With the death of Lash the mark went away. Page 395 White Night

I'd worn a mark for years--an unblemished patch of skin amidst all the burn scars, in the perfect shape of the angelic sigil that was Lasciel's name. The mark was gone.  In it's place was just an irregular patch of unburned skin.

That's the deal with Uriel, he rewarded Harry for that with Soul Fire, to replace Hell Fire. When Lasciel cheated by trying to influence Harry free will to commit suicide, Uriel could step in with his seven words.. I think he could have stepped in sooner than he did, but he felt that Harry needed to learn a thing or two as he did in Ghost Story.

That was flip on my part so I apologize. Still the point is that no one else in the text speaks to anybody who has gone to Heaven.  I get it that Harry is a Chosen One, and as such, is special.  But I don't understand why Uriel would balance anything that Lash does. Harry knows of or at least suspects her presence since he has the sigil and is concealing the fact that he picked up the coin.

Currently my thinking on the Jabberwock is that it is indicative of Lucifer or the Outsiders.

Harry no longer has the sigil, that disappeared when he rejected Lash's last offer that he pick up the coin, then he dug it up and Father Forthill took it.  Harry mentions a "white scar" where the sigil mark used to be.  Harry stupidly perhaps not believing how dangerous they were once touched, picked up the coin to save little Harry, though it would have been better to pick up little Harry to save him from touching the coin.  Then he buried the coin and put a magic circle around it thinking that would keep it's affects contained.  It didn't he still got the shadow of Lasciel in his head.  Having said all of that, picking up the coin isn't the same as accepting the coin.  Harry never accepted the coin even though the shadow of Lasciel put him under tremendous pressure.  He instead transformed the shadow into Lash because of her love for him. That is so rare that it really had never happened before.. That is why he was gifted with Soul Fire.

Perhaps not speak of anyone going to Heaven, but Uriel at the end of Ghost Story hints at it.  Supposedly he was giving Harry a choice, to work for him like Captain Murphy because he wasn't prepared for what comes next.  Harry asks him what he means by that exactly?
Uriel answers; page454

"The part involving words like forever, eternity, and judgement."

I would think that judgement comes first, and I assume that however that comes out, it is Heaven or Hell from there.
