To number eight, it's long been my reasoning that if you theorize something it's not the same as trying to give Jim story ideas, because in the telling your implying he already had the idea and your just looking at what's already there, freeing him up to use it if he wishes... Very glad to see he's actually utilized this fact lol

I figure it was the clue for what he does later with Molly's illusion. It's basically the same thing with extra steps...

It would solve a lot of dangling plot threads, although Blood on his sole was neatly tied up already until River unpicked it. This would allow Jim to concentrate on the build up to the BAT, which I rather think Nicky is bound up with, as he has the Grail. I think Nicky wants to cure Lucifer of Nemesis, which would require all the objects and all the swords.

that'd be too selfless. I think his biblical name gives the key to what he wants, to devour an immortal.. maybe the big G himself

The interesting question is what happens if all the Checkov's guns go off:

1) Harry uses a Darkhallow
2) On Demonreach
3) While holding the Blackstaff

I mean, what's the staff's limit? Does it effectively complete the prison? Can it work on magic you already did (ie, will it cleanse Harry's magic of Justin at this late date?)

in theory, mouse has already cleansed Harry's old black magic from him.

If he even can kill the genoska, might be better off trying to trap him on DR.

I choose to believe DR is too basic and foreign to be Nfected, to believe otherwise pretty much screws reality without recourse and seems like an easy out for nemesis that would have been tried already.

If you've read mouses story the correlation between black Magic and infection is no longer an ambiguous idea, or it's ability to effect mortals, which is pretty much confirmed anyway when Rashid feels it's necessary to examine Harry personally, or list off incidents involving mortals. I think she's quite common, she's the devil in everyone's ear, everyone has a shadow for her to speak through, humans can just override it. Those who can't, quite clearly have their own shadow mirror inside reality to prevent Nemesis room to maneuver.
And thomas became addicted to poison soon after, he craved the love and wouldn't be well fed without it, that's not natural. Nor was Justine's original illness which Kravos likened to a drug addict, which was directly reasoned in book to reduce willpower and allow possession. She acted not only entirely different but in possession of mind reading abilities not natural to what she seems usually capable of. No, glossing over Justine's sickness is blinding oneself to deeper clues, I plain out don't believe medication does anything for her, and despite her tongue and cheek reply in WN that that's why she's normal now, it doesn't have anything to do with it, if she even actually takes medication besides Thomas, whom was literally her medication as per her description of his effect on her. A particularly large dose/bite seems far more likely and proven of an idea. Especially since we encountered another with similar issues in sarrisa... Same issues? Doubt Mab helped her with meds either.
