I think the cullens. The pack, used to be the closest I think, but ever since, Jacob left, and then 2 packs formed... I think they arent as close. I know, they can still hear each others thoughts sometimes, but I still think if they would have stayed together,,, They would have been the closest. And, I dont think The Volturi are close at all, Jane actually pretty much scares me. And, everybody else... So definetley the Cullens, are the closest.
Most defintly the Cullens, because they chose to be a family and they are all very close. They don't have a proper leader because they think of themselves as the same. :)
i think the pacl, bc they depend on each other for everything, and can comunicate telapathically. and also the whole vampire thing is getting wierd, i just want to remind people, they are not real. Ha sorry, im new to this fan thing so im annoying
