Elaine is the wizard the White Council should really be afraid of.

Unless Harry looked into a mirror while using his Sight, there is no way he should know what the sign of HWWB looks like or that he even carries it.  I picture Harry learning about it in one of two, maybe three ways, the last one being the most likely one.

Death Masks, Harry consults with a Loa or Ulsharavas;
  The Ulsharavas would have seen any shadow of an Outsider on Harry if it was there I think.  It said that Harry was stained with the taint of black magic.  Harry answered that not all of it was his, but admitted that he had made a bad call or two, now whether he meant when he killed Justin or not, it doesn't say.  The Ulsharavas says it appreciated Harry's honesty and agrees to look into what Harry is asking.  The Ulsharavas said nothing about the taint or shadow of an Outsider about him, if it was there I think the Loa would have seen it.   The Loa did ask Harry why he does what he does, getting involved with the problems of others? Harry had no answer, he didn't know.  The Ulsharavas remarked that maybe he should know.  So either being around an Outsider leaves the taint of black magic, or whatever the Three Eye addict saw, the Ulsharavas couldn't or didn't see it.

I do not believe Outsider-taint is that easily detected; not even via soulgaze.
The Gatekeeper -- likely the preeminent wizard in the field -- cannot reliably detect it.

If it were all that easy... there are plenty of Wardens.  Just get a new Soulgaze on a suspect, and bam you found the taint.

And Nemesis is even harder than other Outsiders:  Titania and Mab cannot detect it, only infer it after the fact.  (I'm unclear that taint/possession is even all that common a trick amongst the Outsider crowd; do we have any other instances that we know are not Nemesis?)

What are you suggesting?  That the taint of an Outsider is on Harry and that is what the addict saw?  That Eb couldn't see it in a soul gaze, nor the Loa, nor Rashid, who I believed did his own scan of Harry with his eye?  Even if he saw the spiritual scar or taint, did it really mean anything?  Does it mean that Harry is possessed in any way?  Or does it mean something else?

Let's check out what the exact quote is from Storm Front.  page 134-135

Then something strange happened.
   The young man looked up at me, and his eyes rounded and dilated, until I thought they had turned into huge black coins dotted onto his blooThey dshot eyeballs.  His eyes rolled back into his head until he could hardly have been able to see, and he started to shout in a clarion voice.  "Wizard!"  I see you!  I see you,wizard!  I see the things that follow, those who walk before and He Who Walks Behind! They come, they come for you!"

The junkie said he saw things that follow, not something that is part of Harry.
Then on page 136 Harry says he had never met the junkie, and he didn't sense any magical practitioner. So how paraphrasing, "in the hell had he seen the shadow of He Who Walks Behind in Harry's wake?" Harry goes on to admit that he is marked, indelibly with the remnants of the hunter-spirit known as He Who Walks Behind, though the Outsider didn't succeed in what it was trying to do. Then he says those who know how, using the Third Eye would spot the sort of spiritual scar left from the encounter.  But this was an addict, not trained to either spot the scar or taint, nor to recognize it if he saw it.

Then Harry says; page 136

only a wizard had that kind of vision, the ability to sense the auras and manifestations of magical phenomena. And that junkie had been no wizard.

That last is the important bit, that junkie had been no wizard.  Didn't know Harry, or at least Harry hadn't seen him before, yet the junkie was calling Harry, wizard. Yeah, maybe he looked Harry up in the phone book, but still the junkie had to know what made a wizard to call Harry, a wizard!  Let alone what an Outsider was, by name even!  Harry goes on to say on the next page that the Third Eye allows wizards to see things supernaturally invisible or other things as they really are.  Examples of that are when Harry made the mistake of looking at the Skin Walker with his third eye, the horror of that encounter turned him into a fetal ball, or when he saw Murphy with it and saw an angel.  My point? Because he is a trained wizard, Harry knew what he was looking at.. He also said that wizards learn to be very careful with that vision because it can harm them.. As Mac told him only recently, the real vision of who he is would kill or drive Harry mad. 

Yet this addict knew all of the stuff he told Harry!  The important point isn't that Harry bears some spiritual scar from his encounter with HWWB as a sixteen year old, call it a taint if you want, its of no importance.. What is important is who is trying to train up and teach these addicts?  This happened with Sells, ordinary man with a little talent that exploited, turned him into a sorcerer.. He was also one of those making and pushing the Third Eye drug.  To what purpose? 

They come, they come for you!

In other words it is a bit of a warning to Harry, the Outsiders were still after him.

...  Harry and Elaine have soulgazed.  Unless she was nemfected afterward, I'd think it would have shown up.

I'm pretty sure they soulgazed right around the time they became lovers.
Plenty of romantic "gazing into one  anothers' eyes"moments...  Pretty darned hard to avoid, in fact!

My pick for when she got Nemfected would be at the very end; Elaine said Justin "enthralled" her, but I suspect either that the "enthrallment" was intentionally exposing her to Nemfection, or that in the dazed state just after Harry killed(?) Justin -- when we already know HWWB was in the field -- she got Nemfected as a vector into Summer.

You could be right, but then again, depending on how early they became lovers, could have been as early as thirteen or fourteen years of age.  Remember when Harry fought HWWB he had just turned sixteen, and had no clue as to what was attacking him.. Or Harry and Elaine soul gazed by accident unless specifically taught by Justin what a soul gaze was and how it worked.  If it was by accident it could have happened as early as the age of twelve.. At any rate, even if he saw Nemesis or the taint of an Outsider in her, he wouldn't have known what he was seeing.  He may know now, but we have never heard Harry ever talk about what he saw in his soul gaze with Elaine.  He has mentioned before what he has seen in other soul gazes, but never what he saw in the one he had with Elaine.

Harry has also mentioned that the Soulgaze (like other Wizards' Sight phenomena) are "do not dim with time" experiences.  So Harry still remembers (with 100% clarity) the teenaged soulgaze with Elaine, and can consult it with his modern perspective.

If Outsider-traces were there -- and detectible -- modern-day Harry would know.

OTOH, you're right that it'd be really interesting to know exactly what he did see, when he soulgazed Elaine!

What are you suggesting? ...

Mainly, I'm refuting the idea that Elaine's Nemfected-or-Not status is something a soulgaze (or any other magical inspection really) is likely to detect.

Very possible, but one still has to know or have some idea of what they are looking at.  At the age that Harry and Elaine soul gazed, Harry would have no clue that he was looking at Outsider taint or Nemesis.  To your point, Eb soul gazed 16 year old Harry after the fight with HWWB and while Eb mentions seeing anger, he makes no mention of Harry being tainted by either an Outsider or Nemesis.  I think Eb would know that kind of taint if he saw it in a soul gaze.
