Severus pauses, gauging his surroundings with his senses, not yet reaching for his wand. The boy is near, he can hear the slight hitch of breath, can almost see the shape near the water-swollen stream. The rain continues and the trees appear as inky skeletal things before him, dripping and shining in the moonlight that wavers in and out of dark clouds.

Harry runs away and Snape is sent to find him.
