Daria doesn't even panic, just knees him in the groin
Daria: Pathetic.
She quickly lunges at him and sinks her teeth into his neck
Daria starts drinking his blood
She stops once he's passed out and gets up, wiping blood off of her chin
Daria turns and faces you, eyes wide. She has more color in her face and her eyes are sparkling.
Daria: U-um...w-what?
