You’re a werewolf and your boyfriend is Jacob. Him and his pack are friends with the Cullens. You haven’t met them yet.

You’re out for a run in the forest and your werewolf vision helps you see something in the distance. It’s a female running at supernatural speed.

She is Bella and she’s just awoken from giving birth to Renesmee and was dying. She’s a vampire and is currently hunting and she doesn’t have control of her bloodlust as she’s a newborn vampire.

Bella spots you and a primal instinct takes over and she runs at you.

You see this and are in alert. You run away as fast as you can.

The Cullens and Jacob have stepped outside onto the porch and see you run by in wolf form. They haven’t met you either but Jacob knows it’s you.

Then they all see Bella run after you. The Cullens aren’t worried but Jacob is now concerned as Bella is a newborn vampire and doesn’t know that you’re not a threat.
