Chapter 1:
The Windup and the Pitch

"I don't know who's on first and who's on second!" Dean snapped.

"What is second?" Castiel demanded.

"Don't start that," Dean said.

The conversation was still playing in Dean's head. Of course Castiel would know what first was- he had kissed a friggin' demon, after all- not that Castiel and Dean had been talking about the bases… but Dean's gutter mind couldn't- wouldn't stop thinking about it. Dean hated that a demon had been the one to teach Castiel what "first" was.

"First… don't know what second is… kissed a-"

"Dean," Sam said, slamming the laptop shut. "Stop talking about Castiel already."

"I'm not talking about Cas," Dean lied, giving Sam a heated glare.

"Right. And I'm not your brother," Sam rolled his eyes. "If it bothers you so much, why don't you teach him? I'm going to the library. I'll be back in a few hours." Sam gave his brother a pointed look. Dean pretended not to see. Instead, he looked away from his brother and crossed his arms as his brother grabbed the keys to the Impala and went out.

He didn't hear the conversation his brother was having on the other side of the door with the ceiling as he made his way to the parking lot.

"Cas? I know you usually come when Dean calls, but I think he needs some help and he's not going to admit it unless you-" Sam turned around when he heard the flourish of what he guessed was wings. "Hey, that was fast."

"Is Dean alright?" Castiel asked, concerned. "Where is he?"

"He's in the room- but listen first. You need to get him to tell you what's wrong, read his mind or something, I don't care. Just get him to act normal again!" Sam said, frustrated and then he realized Castiel was frowning at him. "What?"

"You realize that I am not Dean's babysitter," Castiel stated.

"Yeah, I know you're not," Sam said, resisting the urge to add, "I am." "But it's your fault he's like this." He felt cheap for using that excuse when he saw the look Castiel got when Dean hurt his feelings. He didn't like the expression on Castiel's face and he could only imagine how Dean dealt with it. He shifted uncomfortably.

"What room?" Castiel asked finally.

Dean stared at the television, flipping through the channels and then cursing when it seemed like every other channel seemed to be baseball. Really, was the universe trying to drive him insane?

"Hello Dean," Castiel said.

Okay yes, the universe was really trying to drive him insane.
