Yes.
No, but his dad does know
Jacob Black
No, Jacob does not know she knows the cullens secret...truth be told, he doesn't know it himself, all he knows is that the legends are not true when they are.
He is good because he fights along side the CUllens in order to save Bella.
Twilight begins by Bella moving to her Dad's house. Then she meets Jacob Black Then she goes to school and meets Edward and the other Cullens.
In Twilight, Jacob Black's great great grandfather is Ephraim Black, who signed a treaty with the Cullens saying that neither can hunt on the others land. -Mrs.Cullen456
Well, there are the other Cullens, Jacob Black, Bella's friends, Charlie, any one you can think of.
Tells Bella about the wolves and the cold ones (vampires) and helps her realise that the cullens are vampires and is her friend
In Breaking Dawn, Irina betrays the Cullens by telling the Volturi about Renesmee, Edward and Bella's half-vampire daughter. She does this because in New Moon, Irina's mate, Laurent was going to kill Bella. Jacob and his werewolf pack intervene and kill Laurent first. Irina is still upset about this in Breaking Dawn, so she betrays them.
In the Twilight Saga Jacob Black was born in the year 1990.
No one killed Jacob Black in Twilight.............or in any of the other movies.
