You are Edward’s sister, you were only one year older then him, and when the battle was about to begin, Edward only trusted you to raise Renesemee if Bella and Everyone else didn’t make it…one day before the battle, you were holding Renesemee, making her a snack because she was hungry!! And Bella saw this and whispered to Edward

Bella: Whispers I think you’re sister will be a good mum

Edward: Nods yeah but she knows she can’t have kids…So don’t brag about kids to her

Bella: Nods ok
