Snowball Fight
Derek should have known Stiles and Scott were up to something when they insisted he get out of the house and come outside. He should have known to be wary when he heard the laughter and whispers while nearing the door; but the werewolf didn't want feel like tuning in on the words at the moment, having just woken up to the shouts of the two friends. And he should have known that on the day of the first real snow, he shouldn't step outside.
The moment he opened the door, mouth open to yell at the two for disturbing him so early, he was pelted with a snowball directly in the face and one on his chest. Slowly, threateningly, the man wiped the insulting, frozen mess off of his face, shaking his hand as he glared at the two.
"What was the point behind that?" He growled through gritted teeth, eyes still narrowed as he took in the two teens. Scott seemed to be rethinking the plan, but Stiles ignored the aura rolling off the alpha, throwing another snowball at him. It was dodged, but it served it's point. They weren't going down without a fight.
Rather than attacking the two, some part of Derek decided he would play along. It had been a long time since he had taken a moment to enjoy any fun the snow might bring; more often, he had cursed the snow - it was a whole lot easier to track in the snow than in the dry ground. Leaning down as if to transform and attack the prey, his hands quickly gathered a ball of snow, and Stiles was hit square in the face.
With that retaliation, a full on war was incited.
In the end, the three were collapsed on the ground. Scott hadn't managed to escape before getting pelted by both the alpha and the human, and he had taken down his flag of surrender and joined in the fight. As their breaths evened out, Stiles moved slightly closer to Derek, resting his head atop the older man's chest.
"My head's cold," he quickly murmured in response to the raised eyebrows. Not bothering to argue with the teen, the werewolf closed his eyes, unaffected by the chill surrounding them. The three soon fell asleep - most certainly an odd sight for any unfortunate traveler that happened to discover them.
