Harry was sitting near the fire when he saw Severus rush outside. Alarmed, he followed.
"What's going on?" Harry asked.
"First snow of the season and the night of the full moon," Severus said, distracted as he held out a large dish to collect falling snowflakes.
"Ah! Good to know," Harry said. "Anything special I need to use?"
"Glass is best," Severus admitted.
Harry dashed inside and grabbed a platter. He tapped a finger on it to make it larger.
Snowflakes preserved and put away, Harry bundled Severus in a blanket in front of the fire to exchange warm kisses.
