Almost all at once, she lost whatever tenuous grasp on reality she had. Blaise could only watch, helpless, as her eyes emptied again and she went nearly feral in his arms. "NO! Please. PLEASE! Send me back. Stop. Let me die - let me!" He had to struggle to keep her steady, to keep her from jolting for the fire or the door. He was gritting his teeth, preparing to scream at someone, anyone, to just fucking help her when Susan stepped into his line of sight, a syringe in her hand. With hardly a look in his direction, Susan plunged the needle into the back of Hermione's shoulder and depressed the plunger. Wordless, Blaise watched the viscous fluid disappear and noted that, almost immediately, Hermione began to weaken against him. A tranquilizer, or a sedative. He took his first full breath since entering the library as Hermione went limp in his arms.
