The bunker feels quieter than usual, the absence of Sam and Dean making the place seem almost too big. You shift under the blankets, adjusting your position as Jack sits cross-legged beside you on the bed, eyes wide with curiosity as the glow of the laptop screen reflects off his face.

“So,” Jack says, tilting his head as the intro to Avatar: The Last Airbender plays, “this is what humans do when they’re… recovering?”

You chuckle, propping yourself up on one elbow. “Sometimes. But mostly, it’s just a classic. You gotta learn about the essentials of childhood pop culture, Jack. This is important.” Jack nods solemnly, clearly taking your words to heart, and you can’t help but smile. He’s always so eager to learn, even about the little things.

As the first episode starts, Jack leans forward, watching as Aang, Katara, and Sokka appear on screen. A few minutes in, he gasps. “Aang was frozen for a hundred years? That must’ve been so lonely.”

His genuine concern tugs at something in your chest. You nudge him lightly. “Yeah, but he finds his people again. And he helps save the world. It’s kind of his thing.”

Jack nods, considering this, then glances at you. “Like Sam and Dean?”

You smile, warmth spreading through you. “Exactly.”

Halfway through the episode, Jack mimics Sokka’s exaggerated arm movements, attempting to “waterbend” along with Katara. You burst out laughing as he waves his hands dramatically at your cup of water, concentrating hard. When nothing happens, he frowns. “I think I need more training.”

You ruffle his blond hair. “Give it time, young grasshopper.” Jack beams at the nickname, clearly proud, and settles back into the pillows beside you. As the episode continues, he gets completely engrossed, occasionally whispering questions or theories. And for the first time since the hunt, since the fear and the pain, you feel okay. Safe. Wrapped in blankets, sharing quiet laughter, and teaching Jack about childhood nostalgia, the bunker doesn’t feel quite so empty anymore.
