Dean was drunk, way past drunk, as Gabriel sauntered in to the kitchen area. Castiel's brother raised an eyebrow at him. "What do you plan to do with him once he passes out?" the trickster asked.
"Put him to bed," Castiel muttered, almost darkly.
"I can think of a much better idea than putting him to bed," Gabriel said and seeing the blank look on Cas's face, he sighed. "Why are you upset?"
"I'm not," Castiel started, but changed his mind as he saw the skepticism flash across the other's face. "Dean asked me a question and I do not like the answer."
"You don't like your own answer?" Gabriel nearly laughed, but didn't when he saw how serious his fellow ex-angel was. "What did he ask?"
"I asked him," Dean muttered. "I asked him how," he paused, trying to remember the exact wording, "I asked him if he was jealous."
"Of what or who?" Dean laughed at Gabriel's question.
"Of Sam." Dean slurred out. Gabriel's face scrunched up momentarily in thought. "Of Sam and you, idiot. Did you think I wouldn't notice? When you demanded to see him?" To Gabriel's credit he blushed. Sam stumbled in to the room, catching himself on the counter.
"Yes, I am jealous." Cas whispered lowly enough only Dean could hear. Gabriel laid a hand on Sam's chest, herding him back in to his room, muttering about sick Sasquatches and them needing sleep. Dean flashed Cas a grin, before trying to stand. Cas jumped to his feet and helped the older Winchester to his own bed. As he turned to leave, Dean drunkenly grabbed his arm and pulled him in to bed, burying his nose in to Castiel's back, falling asleep almost instantly.
Castiel lay awake for hours. Dean didn't let him go once, while he slept.
