You roll your eyes as dean groans in irritation at the front door to the motel, Sammy just walking out on his own to get some jack.
Dean walks over to the edge of the bed you sit at, tying your shoes and examines your expression.
"Whattya' gawking at, Dean?" You mutter, feeling his gaze on your face. "If you pick up on ladies like this, they must not be right in the head."
He blows a raspberry and looks away, "just wondering what's going on in there, kiddo."
You shrug, avoiding the question. "Sammy won't be long, right?" You ask, sitting up, looking at him. Ever since they took you in, you've grown a strong bond between the two. They still prod at your past, but they know when to quit.
He shakes his head, "answer me, please." He says softly.
You sigh, and roll your shoulders. "I'm doing as well as a hunter can be, Dean."you get up, "I'm gonna join Sammy. Pick up something harder if you really want to play detective all night with what happened. "
You get up and throw your coat on, going out the door. You hear Dean sigh before it closes.

The liquor store door chimes so loudly and you almost wince. You look down the checkout stands and see Sammy, back turned to you. You smirk and creep up behind him, hugging him from behind quickly.
"Hey-!" Sammy starts, turning slightly and you grin.
"Relax Sam, it's me. " you continue giggling and you let him go. Instantly his eyes soften and he hugs you. HARD.
"You got me. " he smirks, letting you go, "why aren't you in the motel room?" His eyes drift towards the motel out the door then back to you.
"Dean was getting sentimental on me." You say, "could've sworn it was you who was the caring brother. "
Sammy gets serious. "You're our family now, it's our job to worry about you."
You gape slightly. "Not you too! Geez, are we gonna sit in a circle too?"
He rubs his jaw thoughtfully, "that's not a bad idea."
You groan and move him aside, looking at the drinks. Bourbon, whiskey, rum, and Jack sit in there. Two of each, precisely.
"Good thing you know how to pick the good stuff." You say, practically molesting the bottles as you look over the brands. The clerk looks at you skeptically , not quite sure if he should card you.
It's almost unfair really. One year younger than Sammy and apparently you look 12.
You slide a drivers license up before they can ask, and they nod with dismissal. Taking the bag of drinks, Sammy cheers you on while you carry. And even though he's behind you, you can hear his amused smile in his whoops that echo across the parking lot.

Dean is nodding off when you get back, but jerks awake when you open the door. He grumbles under his breath about noisy kids and comes over.
You're tense, ready for the question when you hear-
"Sam. Dean." A gruff voice says mildly. You turn stiffly, and both Sam and Dean turn.
"It's been a while, Cass." Dean says, and unexplained emotion dances across his eyes.
Cass nods. "Affirmative. I can only take leave so often..." He trails off and stares at you for a moment.
Sammy steps in, "cass, this is-"
"I know who it is, Sam. " cass says softly, looking pointedly at him. "I'm almost always watching. What I don't know is how you wound up together. " he locks his gaze with yours again, and you can't help but edge behind Sammy with the concentration in his eyes.
