Happy Birthday to the cutest smol Oz ❤

(meant to send this yesterday) Happy Brithday Oscar! Have cake!
“It’s … it’s my birthday already? You’re sure?” Oscar asked. He’d completely let it slip his mind. Not many things could sneak up on a master of stealth like him, but dates and holidays were a notable exception. He never remembered when Christmas or Easter was coming until they were there, much like his own birthday.
“That’s the truth, Oz,” Dean replied. He had leaned down on his crossed arms on the table, an attempt to be more at Oscar’s level. It didn’t completely work, but he could at least watch a smile grow on the little guy’s tiny face.
Sam already had his silver knife out of its sheath, but he offered it to Oscar instead. “We got it onto our calendar as soon as we knew. No more excuses to forget it!”
Oscar’s cheeks turned slightly pink. “Th-thanks!” He eyed the knife before taking it with reverence. Sam didn’t let that knife go very often, but one exception wouldn’t hurt. While Oscar hesitated with the knife over the miniature cake they’d brought him, he stammered out a defense of his own forgetfulness. “I-it’s not like I ever celebrated my birthday before. I’m usually too busy is all!”
“And miss out on cake?” Dean scoffed, even as Oscar finally cut into the little cake, an experience he’d never had a chance to try before. “We’re makin’ up for lost time, here.”
Oscar huffed, but didn’t let Dean’s teasing ruin his concentration. The first slice was a fourth of the whole cake, transferred onto a makeshift plate of aluminum foil. With it set aside, he offered it up to the full sized human and tried to ignore how small it looked. “W-well. Thanks again, guys. Better help me eat the cake, since you came all this way.”
Sam helped himself to his own more reasonable slice of cake while Dean accepted the small piece with a fingertip. Even then, they both waited for Oscar to have his own piece and try his first bite of birthday cake before having any for themselves.
“Happy birthday, Oscar.”
