Warnings: warm nostalgia, aching hurt/comfort, and fierce sibling love, itâs the story of how Dean Winchester learned that family isnât just something you protect â sometimes itâs the reason you survive.
A/N: Let me know what you think đŤś
Dean Winchester never expected to become a brother again.
Not after the motel rooms and cheap diner coffee and the way life kept teaching him that loving people usually ended with burying them.
Small enough to fit in the crook of his arm.
Too young to understand monsters.
Too young to know your family was already haunted before you could even speak.
But somehow, from the moment he saw you, Dean decided one thing:
Nothing in this world would ever hurt his baby sister if he could help it.
2007 â The First Time Dean Meets You
Dean is nineteen when Dad walks into Bobbyâs house carrying a baby carrier.
Rainwater drips from Johnâs jacket. Bobby is yelling about something from the kitchen. Sam is frozen mid-step.
Inside the carrier is the tiniest baby heâs ever seen.
Big eyes. Tiny hands. Wrapped in a faded yellow blanket.
âYouâre kidding,â Dean blurts.
John rubs exhausted fingers over his face. âYour aunt died two weeks ago. No other family left.â
Then your little fist curls around his finger.
Thatâs the exact second Dean Winchester loses every remaining ounce of emotional self-control he has left.
âSheâs staying with us?â Sam asks quietly.
Dean crouches beside the carrier.
âHey there, sweetheart,â he murmurs.
You make a tiny squeaking sound.
Dean immediately looks panicked.
âWhyâd she make that noise?â
Bobby snorts from the kitchen. âBecause sheâs a baby, dumbass.â
But Dean barely hears him.
Heâs already completely gone for you.
Dean spends weeks trying to make your first word be Dean.
âSay Dean,â he repeats while sitting cross-legged on the motel bed.
You shove your toy directly into his mouth.
Sam laughs so hard he nearly falls off the chair.
Dean points accusingly. âYou shut up, Sasquatch.â
Two days later, Dean is cleaning one of the guns while you sit in your highchair kicking your legs.
âCâmon, sweetheart,â he says distractedly. âSay Dean.â
You look up from your applesauce.
Sam looks over instantly.
Deanâs eyes go suspiciously glassy.
âOh my God,â Sam whispers. âHeâs crying.â
Dean scoops you up so fast your spoon falls onto the floor.
âThatâs right,â he says, voice thick. âThatâs me. Iâm Deanie.â
You pat his cheek with sticky hands.
Dean looks ready to fight God himself over it.
The bunker doesnât exist yet.
Itâs a cramped motel room with flickering lights and a busted heater.
Dean kneels a few feet away from you with his arms open.
âYou got this, sweetheart.â
You wobble uncertainly beside the bed.
Sam leans against the wall smiling softly.
âCâmon,â Dean encourages. âWalk to me.â
Your tiny brows furrow in concentration.
You fall directly into Deanâs chest.
Dean catches you instantly, laughing in disbelief.
âHOLYâ Sammy, did you see that?!â
âShe took three steps.â
You squeal happily while Dean spins you around the room.
For one whole minute, there are no monsters.
Just your laughter echoing through a cheap motel room.
2011 â Your First Nightmare
Youâre four when Dean wakes to tiny sniffles coming from the other bed.
Youâre crying quietly into your blanket.
Dean crosses the room in seconds.
âHey, hey,â he murmurs gently, lifting you into his lap. âWhat happened?â
âThere was a monster.â
Dean presses a kiss into your hair automatically.
âBut what if it was?â
That question nearly destroys him.
Because one day it will be real.
One day youâll see things no child should ever see.
âIf anything ever comes near you,â he whispers, âIâll kill it first.â
You nod sleepily against his chest.
Dean stays awake the rest of the night.
2014 â Your First Injury
Youâre seven when you scrape your knee badly outside Bobbyâs salvage yard.
The second Dean hears you crying, heâs outside in a heartbeat.
Sam points toward you calmly. âShe fell.â
Dean drops beside you like youâve been mortally wounded.
âOh sweetheartâ okay, okay, let me see.â
âThereâs blood,â you hiccup.
Dean looks genuinely furious at the existence of gravity itself.
âYeah, alright, weâre gonna fix it.â
Back inside, he cleans the scrape with absurd concentration.
Dean winces harder than you do.
Sam watches from the doorway with crossed arms.
âYou know sheâs fine, right?â
Dean glares at him. âShe lost skin, Sam.â
âItâs a scraped knee.â
âSheâs traumatized.â
You sniffle dramatically. âTraumatized.â
Dean points at you immediately. âSee?â
Sam rolls his eyes so hard itâs almost impressive.
Dean finishes wrapping the bandaid carefully.
Then he kisses your forehead.
Dean looks relieved enough to collapse.
2017 â The First Hunt You Learn About
Youâre ten when you finally find one of Dadâs journals.
You sit silently on his bed clutching the book in trembling hands.
Dean stops in the doorway.
And suddenly Dean hates this life more than he ever has before.
He kneels in front of you slowly.
âI wanted more time before you knew.â
âSo all the stories⌠all the times you leftâŚâ
You look down at the journal again.
The question hits harder than any knife ever could.
Dean gently takes the journal from your hands.
âThatâs not an answer.â
Dean forces a small smile.
âListen to me, okay? Me and Sammy? We always come home to you.â
Your eyes fill with tears.
Dean pulls you into his arms immediately.
And for the first time in years, Dean Winchester prays.
2020 â You Patch Dean Up For The First Time
Dean sits shirtless at the bunker table, bleeding from a gash across his ribs.
Old enough to know exactly how dangerous hunting really is.
âYou shouldâve gone to a hospital,â you mutter while disinfecting the wound.
Dean hisses. âAbsolutely not.â
âYouâre impossible.â
âRuns in the family.â
Dean watches you carefully while you work.
Because somewhere along the way, the tiny little girl who used to hold his finger learned how to save him back.
âYou know,â Dean says softly, âyou donât gotta take care of me all the time.â
âYou always took care of me.â
Dean goes quiet after that.
Then gently reaches over and squeezes your hand.
The same way you once squeezed his.
Rain taps softly against the bunker windows.
Dean finds you asleep on the library couch with your head resting against his shoulder while a movie plays quietly in the background.
For a moment, he just watches you.
Not the tiny little kid he carried through motel rooms.
Still the person heâd burn the world down for.
Carefully, Dean pulls the blanket higher around your shoulders.
Deanâs expression softens instantly.
And maybe the Winchester life is messy.
Maybe itâs painful and bloody and unfair.
But in every version of his lifeâ
You were always the best thing Dean ever got to keep.
