Yes, but through this and the way that we see Vin having Hemalurgy, my theory makes A LOT of sense, unless it all just happens to be coincidence.
I personally agree that Vin's mom has hemalurgy, but that brings up a whole host of other questions that don't sit well with me.
warning, random questions coming:
Why give an inconsequential skaa hemalurgy?
Who gave it to her? (Steel Inquisitor or genetics)
Would genetic hemalurgy allow Ruin to control someone, enough to sacrifice one of your kids? ( I think not)
So she needs to have some spikes in her to give Ruin that much control.
Therefore, the Steel Inquisitors (SI), under the control of Ruin, put spikes in Vin's mom to give her hemalurgy.
Did Ruin have that much control over the SI to make them do this? Put spike in a random skaa?
In answer to your questions, which I didn't see last time I posted:
1)Said inconsequential skaa will eventually have a child that has the strongest allomantic ability of anyone born in years, and if above mentioned inconsequential skaa has hemalurgy, Ruin has the perfect tool to be able to control Vin in the future at hand. This does, however, require one of two things. a) Ruin can predict the future (which I doubt) or b) Ruin is able to get information that Vin's mother is sleeping with The High Prelan dude (which he could get from the inquisitors) and just made a lucky guess.
2) Based on above answer, I'd say likely an inquisitor, but it's possible that she got it from some other wacko. I would guess that in order to learn how to create a hemalurgist, you either have to have had it done to you or be able to communicate with Ruin (which tends to entail number 1). However, there could be a "How to make a Steel Inquisitor 101" course book floating around somewhere that we're not aware of.
3) If genetic hemalurgy exists, then I would say yes. I personally believe that genetic hemalurgy does not exist.
4) Yes, I agree that Vin's mother needs to have a spike of some sort somewhere. We don't know enough about her to prove or disprove this, but it's a logical assumption to make.
5) Yes ruin had enough control to make the Steel Inquisitors put a spike in a random skaa. Even before it's freed Ruin has enough control to make marsh fight Sazed, which Marsh wouldn't do without being controlled.
So here's my random question of the day (along with my previous question):
Could the steel inquisitors have given Zane his spike? Why would they do that?
The obvious answer is that they did, but it is theoretically possible that someone else did give it to him. As to why, I would say because they found out he was a mistborn. But then, why haven't they done that with any other noble mistborn?
Thoughts?
