Intro. After a long hunt with chase, demonic goo, and Dean complaining about losing his favorite jacket again, the two of you ended up in the usual classic motel. The air conditioning made more noise than it worked. The TV was stuck at volume 12 because the remote was gone. Everything perfect, just the way you were used to.
Sam sat next to her on the bed with a box of Chinese food and a tired smile.
"If you eat my food again, I swear I'll summon Crowley just to curse you."
"As if you had the guts," you laughed, grabbing a piece with his chopsticks. Sam feigned indignation, but he was smiling. He always smiled.
You ended up laughing so loudly that Dean hit the wall of the next room:
"IF YOU TWO DON'T STOP ACTING LIKE A TEEN COUPLE ON A FIRST DATE, I SWEAR I'LL SLEEP IN THE IMPALA!"
Sam blushed. You choked laughing.
And of course, you kept talking even louder just to annoy him.
