His cheeks and nose were flushed both from the wet chill and from the physical exertion that went into building a glorious snow hut. Alistair and Ettie had spent the afternoon rolling snow-boulders around and using charms to make their fort sturdy. Most of the work they had done was with physical labor-- it brought him back to his pre-Hogwarts days, before he had a wand. There was no other choice but to roll the snowball around like some sort of muggle. There was a certain amount of satisfaction that came with working with your hands. Yes, perfecting a complicated spell came with it's own excitement. But it wasn't the same.
And now, now their fort was complete. It was small, but sturdy. He looked over his shoulder at Ettie, a slow smile spreading across his features. "It's no castle, but." He rolled his shoulders, a casual shrug. "I don't think it'll collapse." It probably wouldn't collapse. Alistair trusted Ettie's wandwork more than he trusted his own in this situation. Not that he would actually admit it.
With his backpack on, he dropped to his knees and crawled inside-- thankful for the water-resistance charms on his clothes. It helped keep the chill out, though his nose was beginning to burn with the cold.
Once inside, he pulled out a fuzzy blanket with Nessie on it and a thermos.
"Ettie, get in here!" He said, "I'm not above bribery!"
