So, this is intended to be set around the time Sam and Dean first met Adam, except, you know without him being dead and impersonated by a ghoul. So uh, it's a bit of an AU I suppose?
The first time he had met her was when his brothers—the brothers that he had only just learned about, brought him to the house of a man named Bobby Singer. The man—who Adam assumed was roughly around the same age as his father, gave him a quick glance, and instructed him to "Stay put" before wandering off down the hall, mumbling something about 'Idjits" and how he "wasn't a damned baby sitter'.
The Milligan boy wasn't left alone for very long however. Shortly after Bobby had disappeared down the stairs, a blonde haired girl came sprinting up them. She stopped just short of the top, her eyes catching sight of Adam. She gave him a brief look-over before speaking. "So, you're the other kid, huh?"
He nodded. "Names Adam"
"Jo." She walked the rest of the way to the room, leaning against the door frame, arms crossed over her chest. "You know how to shoot a gun Adam?"
Part of him wanted to say 'Would I be here if I did?' but instead he shook his head. "Nope."
The girl stood there for a moment, observing him with large, brown eyes, before cracking a smile, and straightening her posture. "Wanna learn?"

"You're holding it wrong. Do it like this." Adam did his best to ignore the way his cheeks suddenly began to heat up as the blonde girl pressed against his back, reaching out from under his outstretched arms to take his hands into hers briefly, and reposition them.
He glanced over, glimpsing her out of the corner of his eye, and allowed a smile to edge its way across his lips as she stood on tip-toes, to try and peer over his shoulder at the gun.
"What's so funny?" She asked, returning his glance with a fleeting one of her own.
"You're…really short."
Jo frowned, pulling back and playfully giving him a punch on the arm. "You're just freakishly tall. In case you haven't noticed, giants sort of run in your family." She flashed him a cheeky grin and added "At least I can shoot a gun."
