Kiri sat at the end of the table, shivering slightly. She watched the proceedings numbly, not quite sure of what had happened, not quite sure of what was happening. Somehow, it didn't register. One of her worst fears was in fact drowning, and wading through dungeons that were halfway filled with water - and not knowing why - had brought out that fear in full strength. Obviously.

She'd had enough presence of mind (or instinct) to grab Sol, her pygmy puff, before hurriedly being ushered out of the common room, and now she removed him from her pocket and put him on the table. His fur was soggy, but he didn't seem to be hurt. He looked like a tennis ball now.
Kiri looked around blearily. For the first time since coming to Hogwarts, she realised that the Slytherin Common Room was... below the lake! Panicky, she grabbed Sol to calm herself. The little pygmy puff squeaked in protest at being handled so roughly, but Kiri hardly noticed. Another thought, as chilling as the water of the lake, had just occurred to her. What if the teachers had forgotten someone down there?! Sure, they weren't running around frantically or doing anything else that would indicate that someone was missing, but Kiri began looking up and down the Slytherin table to see if everyone she knew was accounted for.
