The Cullen's were a group of attractive vampires that were hundreds of years old. It consisted of the parents Carlisle and Esme. And then their adopted kids Edward, Alice, Jasper, Rosalie, and Emmett. And then recently Bella had came in the family. And they were extremely close and like they wanted Bella to fully time be there. But Edward didn't wanna bite her yet. Yada yada.
Unfortunately. You were her sibling. Younger sibling. And so when James popped up. Bella spilled out everything. About the Cullen's being vampires. Ect. Told you everything. Like spilled it so now you were apart of that. But then Bella ran away cause James tricked her into coming to the old ballet studio. And ended up going to fuck her up. Unfortunately you were now in the car going to save Bella. It was you, Edward driving, Carlisle, Alice, Jasper, and Emmett. In a cramped car.
They were following your directions because they thought you'd know better. Unfortunately you and Bella had different moms. So, literally you were probably the last person they should ask. Edward was freaking out in the front seat.
