Dean was bored. He was supposed to be researching. But Dean never did the research. That was Sammy's job. So instead he decided to kill time by watching YouTube. He decided to search for a song Sam mentioned earlier. He found himself smiling and laughing by the end of the song.

That's when he heard that familiar ruffling of wings and Castiel's voice, coming from directly behind him.

"Hello Dean, why are you laughing?" Dean jumped slightly.

"Damn it, Cas! You can't just sneak up on me like that!" Dean turned around and pulled the earphones out of his ears. Despite Dean's sudden out burst, Castiel didn't even flinch.

"I just wondered what you found to be so funny." Castiel shifted uncomfortably from where he was standing. Dean sighed and also shifted awkwardly.

"Well… I was listening to music. Sam found a song that he thought perfectly described you. You gotta hear it. It's called 'angel with a shotgun.'" Dean handed his earbuds to Cas.

Castiel, remembering how he found Dean, stuck the strange things in his ears. Dean then restarted the song and watched Castiel's face as it played. He smiled to himself as Cas started to squint.

When the song ended Cas turned his eyes back on Dean.

"I... like it." He pulled the buds out of his ears and stared at them in interest. "Though I don't understand why an angel would require a firearm. We are well equipped with many other powers. Is the song supposed to depict the civil war in heaven? If so, I don't find it quite as amusing." He frowns. Dean chuckles at Castiel's remark.

"No man, It's just…" He trails off, wondering if he should tell him what he really thinks of the song. When he gets a confused head tilt from Cas, he decides to go with it. "It just – I kind of reminded me of… us." He shifted awkwardly in his seat. Getting nervous he started to babble. "Not that there's an 'us' or anything, I mean, there could be, I you w- wanted there to be."

"I don't understand… how does this song relate to us? Did you mean the fact that I rebelled for you?" Using air-quotes, "And what's an 'us?'"

Dean sighs and grabbed his jacket. Shrugging it on, he walked to the door and took his keys.

"I'm gonna get some pie." Walking out, he yelled over his shoulder. "You can come too if you want."

Cas stood for a second and decided to follow Dean.
