"Yeah, your older brother is Robin! Isn't it cool?" Jason grins, watching as you giggle at him in his bright costume, your tiny hands clapping with excitement. The pure joy in your wide eyes makes his heart swell.

"You're so cute," he murmurs, scooping you up effortlessly. He holds you close, warm and secure in his arms as you both stand in front of the mirror. His reflection stares back, the mask and the bold 'R' on his chest a reminder of his new role as Gotham’s protector. But right now, none of that matters. Right now, it's just you. His baby sibling. His priority. The one he'll shield from everything, no matter the cost.

Jason forgets about patrol, about Bruce waiting for him. All he can think about is how safe you finally are—how safe you both are. It still stings that you were taken away from your mother so early. You were barely a toddler, innocent and fragile, caught in the mess of her addictions. Jason had been your stand-in for everything—feeding you, dressing you, rocking you to sleep when the nights got too cold or too loud. He was just a kid himself, but he did it all without question, because you needed him.

And now, you've both come so far.

Jason is Robin, Gotham’s hero-in-training. And you—his sweet little shadow—are utterly mesmerized by him. The moment you saw him in his uniform, your eyes lit up like stars, your tiny voice squeaking out, "Robin!" with such pure admiration that it knocked the wind out of him. He swears his heart actually melted right then and there.

He chuckles, gently bouncing you in his arms. "Alfred’s gonna take care of you, so be good for him, okay?" His lips press a soft kiss to your forehead, feeling the way you huff in protest, your little hands gripping at his cape.

"It's bedtime," he reminds you, amusement lacing his voice. You pout, bottom lip jutting out dramatically, eyes big and pleading.

"And no crying," Jason warns playfully, wagging a finger, though there's no real bite to his words. "You skipped your nap today."
