A is for Angel
Dean watched Castiel. They had been on the road for days. Castiel was not used to the constant travel like this. He was so used to flying to where ever he needed to be. Being human was still strange to him.
Dean could see how tired the former angel was, even if he denied it. Castiel's shoulders sagged, and his eyes drooped. He needed this rest stop more than Dean did.
"Cas," Dean said gruffly. He walked up to the former angel.
"I know we should be on the road-" Castiel started.
"You are tired, Cas, I won't let you sleep in the impala again. Sam's already working the case. A few hours' delay won't hurt. Everyone needs sleep, even angels," Dean said.
"I'm not an angel," Castiel said, looking away from Dean.
"Yes you are," Dean said, moving in front of him.
"My grace-" Castiel started.
"Doesn't matter, you will always be my angel," Dean said grinning at the other man. "With or without your grace." He made sure to get the point across by pressing his lips to Castiel's in a kiss.
Castiel's breath hitched, and he took a step back from the other man. "I am still not used to this side of you," he said a hand coming up to his mouth.
"Is that a bad thing?" Dean asked with a grin. Castiel shook his head. "Now get some rest, we've got some witches to hunt."
