The funny thing about everyone's comments here, which I completely agree with, is that no one expects Jacob to grow up and mature on his own. At the same time, how can Jacob grow up and learn respect if he is forced to by Nessie, if he actually has no choice?
This is one reason why I hate the imprinting scene (among many reasons). And I hate it because it hurts Jacob. I know that sounds bizarre coming from me, since I make it clear I detest him. But that was Jacob's big moment, and it isn't going to come around again, ever. He destroyed Bella's reunion with Nessie. There is not a second in Bella or Edward's life where they can actually revel in the joys of parenthood with their daughter as just a little girl whose future is bright but remains unknown. They already know exactly who she is paired up with, who she is getting married to and who she will be sharing a bed with. There wasn't anything Jacob could do about that at that point, the only thing he could have offered to them was a little respect.
And due to the finality of what happened, I really don't see any more stories coming from SM based on Nessie and Jacob. We already know what is going to happen. Sure, there may be some dustups between the two, but Jacob will always back down, and Nessie knows that. And because she knows that, she likely won't take him to task very often. Whenever she does take him to task, how will we ever know when Jacob is sincere in his apology for his actions? That is assuming also that Jacob apologizes several years after the fact, and only at the prompting of Nessie who forces him to do so.
Unfortunately, the imprinting scene reveals a Jacob of absolutely zero reflection and self-examination. Because of that, I have little interest in any additional story about him. The only story that might interest me is if he had to fight for Nessie, but SM's interviews and the nature of imprinting and the info from the Illustrated Guide all point to Nessie and Jacob being a foregone conclusion as a couple.
Now, throw in a plot twist where the imprinting connection is somehow magically broken between the two, and you've got something. Because I can only gain respect for Jacob if his shortcomings are something that he sees himself and not something that is forced upon him.
This is assuming that SM, if she ever does write in the TW world again, sees Jacob as someone who needs to grow up. The way the story is told, SM may very well think that Jacob is near perfect just as he is. There wouldn't necessarily be any confrontational scenes concerning Jacob's past. After all, Edward calls Jacob his brother and his son. It seems to me at that point that all is forgiven.
P.S. Just to make clear, I'm not looking forward to any stories involving Jacob because his journey ended in becoming a two-dimensional, boring character. SM said that Emmett had eventually become something of a stock character for her. That is what happened with Jacob, he was Emmettized, he has no depth, so he ultimately becomes as uninteresting as he is aggravating.
"It will take an amazing amount of control,” she mused. “More even than Carlisle has. He may be just strong enough…the only thing he’s not strong enough to do is stay away from her. That’s a lost cause.”
