It's the same for everyone it's inherited. If you mean Leah then she just has it in her blood. When vampires are around the ones who have the gene in their blood turn to werewolves. But really there is no werewolves in twilight, in breaking dawn it turns out that they really are shape shifters, werewolves would need full moon.
Real werewolves don't imprint, but the shape-shifters in Twilight do. They cannot as they are infertile which is a bit sexist. All the males have fully functioning genitals, but the females don't.
Twilight, no doubt.
LOL! werewolves are fake. too much twilight?
Colin and Brady are two teenagers who become werewolves in Breaking Dawn-the 4th book.
Yes they do I am one. no ofcourse not,these all r superficial,fictional characters.
Jacob from Twilight?
seth and Leah
Twilight
yes, and so can the vampires in the twilight saga. the werewolves in the twilight saga arent actually werewolves as well, they are just shape-shifters that happen to take the form of the wolf because of their ancestors.
You are born a werewolf, but you don't actually become one until you are a teenager.
In twilight:eclipse.
I think all the young werewolves went to school before they changed (became werewolves.) Not sure if they go to school now they are werewolves though.
