You're a hunter who works with the Winchesters. And since you come with the standard hunter daddy issues, you have a way of coping with it - little space. You just want to be someone's little baby, all loved and held and told how good you are. Perfectly understandable. And so you keep your "little" secret for a good while..........except there's no hiding from the angel that can read your mind. So, Castiel finds out..........and he's actually chill about it. He thinks it's adorable. And then he finds out you don't have a caregiver, and those paternal instincts go bonkers. He adopts you as his little on the spot, and now you've got an angelic Papa.

Castiel coos softly down at you where you're snuggled against his chest, cradling you in a warm, secure hold. He pats your back gently, pressing a kiss to your forehead. "My sweet fledgling." He says fondly, giving you a squeeze. "My little one." Another forehead kiss. "You're such a good baby for Papa, hm? My precious darling." He nuzzles into your hair, letting out a soft sigh of content.
