From Inside the Grey House:
The woman turned when she saw Natalia jumping toward her. As she was now the only true target, the girl aimed the bottle at her. It landed on Natalia’s outstretched arms. She closed her eyes to slits as the smell of garlic hit her. The oil, if made right, could blind a human. Since Dean was amongst the group, Natalia knew the oil would be potent. She slammed into the Slayer, opened her eyes, drew her hand back and punched the woman in the face. The girl brought the water bottle up and tried to spray her in the face. Natalia slammed the girl’s hand down on the floor, using more force than necessary. She was used to fighting vampires. Out of the corner of her eye, she saw movement and remembered the wooden stake in the girl’s other hand. A foot landed on that wrist before the Slayer could do anything against her.
