I'm assuming your question is guessing later on...not in BD, but if the story progressed. I would say most definitely. There's a lot of fan fiction out there on this topic, and for me, what the other books have talked about with imprinting, I would have to say absolutely.
Stephanie probably isn't going to write a sequel, but we can pretend on www.bellasdiary.com
It's the diaries' of the characters.(Bella, Jacob, Nessie, Edward, and Alice)
It's an amazing site, I love it.
Bella's diary is updated monthly, and the rest of the characters' are updated weekly.
I think they are well suited to each other! The book gives the impression that they are soul mates. Renesmee loves Jacob a lot and always misses him. Renesmee is truly happy with him. Jacob loves Renesmee more than anything, he would be willing to die for her. I think that Edward and Bella would do not oppose to their getting married, though not like it. Bella knows Jacob and know that Renesmee is always safe with him. I believe that they are happy together forever!
