I liked the two packs because I loved it when Jake became the Alpha that he was always meant to be. I couldn't stand the way that Sam had taken his and Seth's wills away. It was terrible. So, when Jake took his stand as the rightful Alpha, I had the biggest urge to stand up and applaud him. Then when Seth followed him, it just made me love Seth more. And I was excited when Leah followed, but I have to admit that I wasn't really expecting it. I guess that I should have, but they never really seemed to get along very well, so it surprised me.
I'm not really sure what the future has in store for the two packs, but I think that at some point Sam is going to want to stop phasing so that he can settle down and have a family with Emily. But others like Quil and Jake will keep phasing until their girls grow up some, then Jake will just have to keep up with his phasing so that he can be with Nessie.
