ジェイコブ・ブラック Jacob's pack ( please do not read if あなた haven't read breaking dawn)
In breaking dawn Jacob forms his own pack. I was confused because durning the Volturi scene Bella says something about Sam being the Alpha scaring Aro...but isn't Jacob an Alpha too?
Also...when he returned to La Push...did he rejoin Sam's pack or keep his own? So are they're two packs at the end of breaking dawn and Sam and Jacob are both Alpha's or just the one again with Sam as Alpha and Jacob as Beta?
