Draco stiffened visibly before, with a whispered, "Jesus fucking Christ, Astoria," he stalked away from Theo and Blaise, interrupting the confrontation between the two women. Blaise wasn't the only one watching now as Astoria tinkled out a laugh, pressing her body against Draco's tense form before turning and heading towards Theo and Blaise with a satisfied smile. Blaise saw Hermione's eyes follow the witch, and thought for a brief moment that she would throw that knife at Astoria's exposed back before her eyes shifted over, and up, landing on Draco. He couldn't hear what she said to him, but the sneer on her face spoke volumes. He didn't know, couldn't tell if Draco responded, but he was forced into motion when Hermione stalked towards the door. Her steps were unsteady, her hands were shaking, and he knew she was overdue for her potions. He followed her from the room, not bothering to spare Draco, Astoria, or anyone a glance as he did so.
