The Mistletoe

Castiel looked up at the green plant with white fruit, contemplating the strange branch. He reached up and pulled the plant from the doorframe it was hanging from and walked past the confused humans that entered the diner he was leaving.

With a quick flap of his wings he arrived in the current motel room that the Winchester brothers where spending Christmas.

The brothers were not inside but down at the closet shop buying each other a gift for the festive season. So Castiel hung the plant above the door to the bathroom and then sat down before the TV his head resting stiffly in his hands.

Another half hour passed before the brothers finally returned arguing about one of the items Dean had brought. They were startled to see the angel sitting there, but when once he told them that he wasn't here on business but to simply ask a question both brothers relaxed visibly.

Dean entered the bathroom, Castiel followed standing under the plant, waiting patiently. Dean walked out moments later brow raised.

"What?" He asked, annoyed.

"What is that plant?" Castiel asked, looking up at the plant. Sam tilted his head from the bed and burst out laughing, baffling Castiel further.

"What the fuck!?" Dean yelped, jumping away from the angel. "Sam!"

"I didn't put it there," Sam snorted.

"I did, it was hanging in the diner, so I put it up here," Castiel shrugged. "What plant is it?"

"It's mistletoe," Sam explained, still laughing.

"Did Sam put you up to this?!" Dean growled, Castiel looked at him confused.

"No, why are you so upset?"

"Cass, that's mistletoe," Sam grinned, "When you stand underneath it with someone you must kiss them."

"Why?"

"Just a tradition," Sam grinned. "Don't leave Dean hanging! Kiss him!"

"Sam!" Dean snapped, pushing the angel away from him, when the angel suddenly puckered up and leaned forward.

"You don't want me to kiss you?" Castiel asked, hurt.

"No! God no!"

"Would you prefer Sam to kiss you?" Castiel asked, naively.

"Cass! Seriously, I'm gonna kick your ass!" Dean snapped, "But first I'm gonna kill Sammy."

"Just because you cannot kiss me?" Castiel murmured. Sam burst out into new laughter only to be tackled to the ground by his brother. Castiel shook his head, before he grabbed his mistletoe. "I think I will find Uriel. I think he'd like this tradition."
