I just had a thought. Nessie can't have Quileute blood from the Ateara's because of Molly. Molly married into the Ateara family and not the other way around, so she took Swan blood into the Ateara family and not Ateara blood into the Swan family. I'm not saying there's not still a link, or denying the possibility that somewhere along the line the Swans have married into other native families (It's quite possible actually considering the Swans have probably been in Forks for a long, long time).
I read that but I still wonder about the genes because the family trees made a point of listing who carries the wolf gene. You would think it would be better if both members of each couple carried the gene. Survival of the species. But on the happiness front, Kim liked Jared before he ever noticed her. It was love at first sight for Sam and Emily and the book said Quil would be perfect for Claire because he'd be whatever she needed (brother, friend, lover). Why wouldn't they end up together?
Yes Kim liked Jared before they got together but I've liked a lot of people in the past (don't even get me started on my teen years ) but that doesn't mean that they were all the right person for me. Yet with all the imprinted couples there's love there. I don't think that can be explained by the imprint itself. Sure even if imprinting is love at first sight (which it could be), if the imprinted couples had nothing in common then they wouldn't last/ would have problems. They have to enjoy each others company. I just find it hard to see how imprinting would not only find your perfect genetic match but also the person you get on with best/have the most in common with etc. I could be completely wrong, imprinting could solely be for genetic purposes to either make the wolves stronger or give them the best chance of carrying on the line, I just think an element of it has to be personal too.
Plus Jacob has a double dose of wolf gene. He wouldn't need someone strong like Nessie. The wolves are all bigger than those of Ephraim Black's time and there are more of them than ever. But I think there's a trend here.
You could be right on the double dose front. In fact, I think it's a really good theory. But maybe, because he's an Alpha he does need it now that there's two Alpha's. It says in the guide that Sam wasn't really an Alpha until Jacob rejected the title when he first phased. Sam was a kind of stand in. I think it mentions in the introduction on wolves that Sam only came into his Alpha powers (being able to order unbreakable commands) when Jacob rejected. Now that Sam has the powers of a Alpha, maybe his children will also inherit the title, like Jacob's children will. I'm really specualting now, but perhaps Jake's children need to be stronger in order to fight off the competion? Or maybe you're entirely right on the double dose side, who knows!
You seem to be as interested as me in all this stuff, and I love it! It's rare to come across someone else who thinks a lot about the inner workings of imprinting!
I have a very 'out there' theory on why Jacob imprinted on Nessie. If imprinting is about genetics and stronger wolves and carrying on the line, then surely it must have something to do with preserving the wolves/wolf line too? If Jacob had killed Nessie then a fight would've definitely broken out between the Cullens and the wolves. All the wolves would've joined in and no matter what the outcome, a lot of the wolves would've died, if not all. If Jacob hadn't imprinted then a big chuck of the wolf line would have be obliterated, so maybe he only imprinted as it was the only way to keep the wolves going? As I said, it's a very 'out there' theory and I'm sure how much stock I put in it myself, but I like to use it as an easy excuse in my stories to carry on my Blackwater obsession!
