Wait.

So what's pure speculation and what's WOJ?

If something is WOJ, when and where did it happen? Who can confirm?

Word of Jim, something he said at a book signing or some other gig..  Most place that above what he wrote in his novels, some of us do not..  Not always but sometimes WOJ seems to contradict what he was getting at at the time he wrote the book.  There are those where who  keep all WOJ on record. and you can find most things that you are looking for.  Then there is the stuff that claims to be WOJ but turns out are made up out of whole cloth, urban myth, yet taken as gospel over what was written in the books.. That has lead to some really hard feelings between the what is written in the books verses WOJ crowd, until someone comes clean and says that Jim never said this or that.. Apparently Fitz is one of those hotly debated subjects.

Could you please define 'great moral character'? It just seems like one of those 'fuzzy' opinion things.

Also, remember, she was engaged to the Loup, and I think there's a scene where she tells Harry at least part of the reason is because he's the most destructive thing out there.

  By her lights, tis a judgment call for sure, she was honest as only a wolf or a dog can be honest, the Alphas would have turned into a mess if it weren't for her..

HA!

 Makes sense because red heads are supposed to have bad tempers...

http://en.wikipedia.org/wiki/Red_hair

"Red or reddish-tinged hair is also found in other European populations particularly in the Nordic and Baltic countries as well as parts of the Netherlands, Spain, Belgium, France, Greece, Turkey, Portugal, Italy, Germany, Russia and South Slavic countries."

 Yeah, it is all about the right combo of genes, it isn't good to generalize too much about any group.

So...Jim didn't actually say Fitz is cursed, Serack did...?

It's because he has red hair isn't it? Ron Weasley had red hair! Ginger power!

(Even though I have brown hair  )

 He could also be related to Gard, lots of Scandinavians have red hair, remember the famous Viking, Eric the Red?

I still think that fitz can't be a wolf because we have a wolf character. it would be like a new cop joining with murphy-what's the point? we have a couple of wolves already. IMO, that means that 1. either fitz is a wolf but will not be significant, or 2. that he isn't a wolf and would be significant.
since fitz got a lot of screen time in GS, i say it has to be the second

  I can see Fitz at some point becoming a Holy Knight, but sorry but I agree to me it just doesn't fit as a wolf.  I cannot see a child of Tara West, raised with her values in the woods of the Pacific Northwest, falling into the gutter to be pushed around as he was by a second rate sorcerer.  So as much as his description fits some things most of the stuff just doesn't fit.

Fitz may well be too young to have had his first transformation.  It would be entirely in-genre for such curses to remain inactive "until his 18th birthday"...or 16th, or 21st, or whatever is particularly significant.  As far as Tera West's possibly unconventional parenting style, it's worth remembering that she isn't human, and lost her mate, who was human, several years ago.

One thing to remember is, according to the curse, it's almost certain that West and MacFinn had a child.  Since we know that they never married before MacFinn's death, that child would be a bastard.  Fitz means bastard.  He has physical characteristics that resemble Tera West and MacFinn, acts in a semi-wolfish sort of way socially, and we apparently have a WoJ that Fitz is cursed.  These are rather a lot of factors to dismiss in order to claim it's a coincidence.

I realize JB's also said that he had no plans to use Fitz as a character again, but you never know.  That doesn't contradict any of the above; it could mean that JB doesn't plan to bring the Loup-Garou curse back into the plotline.  This makes sense--the Loup-Garou curse was covered in FM, and if it originated from Saint Patrick (who was a bloody idiot, if so), then it doesn't seem to be an integral part of the long-term plotline.

Okay, but wouldTera conceive as a human or a wolf?  Have one child or a litter of pups?  Yes, Fitz means bastard, but people have names like Fitzgerald and they are not bastards, an ancestor was.  Surely Fitz knows what is coming if he is indeed her son, yet how long is he going to stick around those kids?  I mean can you see Zero leaving him?

The wolf speculation comes from:
A) Tera West was supposed to be in GS
B) A lot was done through proxies
C) MacFinn's curse can't die, but he didn't have a kid (that we knew of)
D) Fitz's skin was dark, almost bronze, like native american dark
E) Fitz's hair was red, like an Irishman's
F) Fitz's eyes are roughly the color of Tera West's
G) Fitz is Cursed

Taken together, it seems to point to Fitz being the result of Tera West and Harley MacFinn

But Tera West wasn't in Ghost Story, or at least I do not remember reading about her.
 Yeah, but the  proxies mentioned where Mab, Lea, Demonreach, maybe Uriel.  Nothing mentioned about Tera West.
 If MacFinn died, then either his nearest relative caught it, God wouldn't that be terrible?  Or the curse died with him.  The curse was on his family, when his family died it would die with them.  No evidence that Terra West had a litter of puppies.
 Fitz's skin is dark.. Well, he could be Hispanic, Italian, half AfroAmerican, Middle Eastern, Micronesian, and any other combination that produces darker skin, East Indian...
 Fitz's hair is red like an Irishman.. There are red haired people in my family, we are Danish.  There is a famous Viking named Eric the Red, because of his red hair, lots of Englishmen have red hair. 
 His eyes are roughly the color of Tera West's?  Lots of people have that eye color.
 Fitz is cursed.. Okay, WOJ on that one, but he also said Fitz in more books not likely.. So why say anything at all?  However there are more curses under the sun than you can shake a stick at, stay tuned.. You could be right, or just jumping to conclusions.
