"How long are we going to just sit here?" Castiel asked.
"I don't know, depends how long it takes for Sam to get inside." Dean twisted the binoculars to focus the lenses but found no sign of his brother.
"I'm cold," Castiel muttered next to him and Dean let out a sigh, his breath coming out in foggy puffs.
"I know its freezing."
"Can we turn on the car?" Castiel reached for the ignition but Dean slapped his hand away.
"No, we can't draw any attention to ourselves." They go back to sitting quickly, Dean stared out the house down the street through his binoculars and Castiel flexed his fingers in a poor attempt to keep the blood circulating through them. One of the lights in the house flicked on in the house but Dean couldn't tell if it was Sam or the witch in the living room.
"I've never been cold before." Dean looked away from the house and over to Castiel who was studying the frost that had formed on the window. Sometimes Dean forgets that Castiel wasn't an angel anymore, that there are still things he doesn't really understand. This is his first winter being human and everyone else in the world is getting ready for Christmas while Castiel was just trying to figure out why his fingers kept going numb.
Dean reached back and rifled around in the back seat till he found a threadbare blanket. "Come here."
Castiel slid down the seat over to Dean, not looking completely trusting of the hunter who was suddenly paying attention to him. Dean gathered Castiel's hands in his, they were stiff and icy, definitely colder than he expected. He ran his thumb over Castiel's knuckles and breathed hot breath over the frozen skin. "Is that better?"
"Yes," Castiel nodded, "thank you."
"Sam might be awhile. Why don't you try to catch a few z's while we wait?" Dean pulled Castiel down, pushing his head down against Dean's shoulder and wrapped an arm around him. Castiel seemed a little unsure but when Dean put the blanket over his shoulder Castiel curled up next to Dean trying to stay warm.
"I want to help," Castiel said trying to suppress a yawn.
"You will," Dean assured him. "But there's no point both of us trying to keep watch if we only have one binocular. I'll wake you up in a bit so we cans switch."
Castiel nodded silently and pulled the blanket tighter around himself. When Dean felt Castiel's breathing turn slow and even he grabbed the binoculars again, he rubbed his hand up and down Castiel's spine. He was glad that at least they didn't have to worry about freezing to death while they waited for Sam.
