¡°Let me through, please,¡± came Percy's voice, and he came bustling importantly through the crowd. ¡°What's the holdup here? You can't all have forgotten the password ¡ª excuse me, I'm Head Boy ¡ª¡±
¡°And then I saw another dot, moving fast toward you, labeled Sirius Black¡I saw him collide with you; I watched as he pulled two of you into the Whomping Willow ¡ª¡±
To his great surprise, Hermione did not appear either excited or intrigued by the news. On the contrary, her face fell, and she bit her lip.
