Mya is 13, this is set in the bunker with John, and Mary alive.
"Hey dinners ready." Mary calls out to her two sons and husband who were researching in the library. "Thanks Mom. I'm gonna go grab Mya." Dean sighs closing his laptop and heading down to his daughters room. "Hey Sweetheart, time to eat." Dean calls out knocking on the door. "Not hungry." She mumbles cuddled up in her bed. "You need to eat something. You have been locked in your room all day." Dean says concerned. "Im not hungry." She repeats louder and with a lot more attitude. "I don't care. You are coming out here and eating with us." Dean says raising his voice to match hers. "Leave me alone Dad! I am not hungry I don't want to eat!" She shouts. "Mya Winchester! Get your ass out here, now!" He commands. Mya pulls herself out of bed, knowing he wasn't messing around and opens her door. "Im sorry for yelling. I'm not hungry." She whispers eyes glued to the ground. "Alright. That's fine. Grandma made dinner, you are going to come out and sit with us at least." Dean says gently but sternly. "Ok." She whispers shuffling her feet and following her Dad to the table of people who just heard their argument. She sits in her seat between Dean and Sam with her head down staring at her plate. "Hey." Dean says nudging her. "What?" She whines looking over to him. "Knock it off. Eat something." He says giving her a warning look. "You said I didn't have to. I'm not hungry." She snaps. "Snap at me one more time and you're done. You haven't eaten anything today, you need to eat." Dean says feeling the judgmental glances from his parents. He hates how they criticize his parenting every step he makes. "I'm sorry..." she whispers daring to glance up at him. "I know Sweetheart. Take a couple bites and then you can go back to your room." Dean sighs grabbing her plate and putting a scoop of mashed potato's and a piece of chicken. She eats half her chicken and a few bites of the potato's. "I'm full." She whispers pushing her plate away. "Alright. Clear your plate." Dean sighs hesitantly. "Thank you Daddy." She says giving him a hug and taking her plate to the kitchen. She comes back and goes around the table giving everyone a hug. "Good night Munchkin." Sam chuckles hugging her back. "Good night." It was completely silent until they heard her bedroom door close. "You're alright with her speaking to you like that?" John questions taking a bite. "John." Mary warns. "No. She's not usually like this." Dean defends. "So is that a yes?" John chuckles. "No. She isn't trying to be difficult. She's upset." Dean says anger lacing his tone. "Is she alright?" Mary questions furrowing her brow. "Her stomachs been bothering her." Dean explains. She never told him that but he knew his daughter. Her moodiness and eating habits making it clear. "Her period?" Mary questions making him grimace and shake his head. "I've yet to deal with that one." He sighs gratefully. "Afraid of a little blood?" She taunts. "When it involves my kid yeah." Dean chuckles. The family makes small talk and discusses the case while finishing their dinner.
"Daddy!" Mya screeched from her room making Dean immediately get up and hurry to his daughters room gun drawn. Sam and the rest of the Winchesters were short behind him. He pauses to see her kneeling on her bed vomit all down the front of herself and comforter. "Shit." He mutters placing his gun in her dresser and grabbing her trashcan and holding it out to her to contain the next round. "I'm sorry." She cries leaning forward and filling the trashcan with more vomit. "Breathe Sweetheart." Dean soothes rubbing her back. Mary moved to take her hair tie off her wrist and tie up Myas long blonde hair. Sam had gone to go get her some water and handed it to Dean who handed it to Mya. "Thanks." She whispers taking a small sip and giving it back. "You alright?" Dean questions trying not to look at the chunky goo coating every inch of her bed and body. She nods and looks to the ground embarrassed. "Im sorry. I woke up and I was just throwing up. I didn't have time to get to the bathroom." She says tears running down her face. "It's alright Sweetheart. It happens." Dean comforts. "How about we go get cleaned up a little?" Mary offers. She nods and slowly gets out of bed trying to avoid a bigger mess and follows Mary to the bathroom. "Great..." Dean sighs not looking forward to cleaning any puke up. "Joys of parenting." John chuckles putting a hand on his sons shoulder. "Yup..." Dean sighs starting to ball all the blankets up. "Need anything?" Sam questions. "Nah I'll good Sammy." Dean sighs heading to the laundry room. He puts fresh sheets on her bed and then knocks on the bathroom door. "Hey Sweetheart. It's Daddy, you need anything?" Mary opened the door and sighed. "She got sick a few more times. Just got settled in the tub." Mary says voice soft. "I grabbed her some clothes." Dean sighs handing them to his mom. "She's alright Dean. It's just a rather nasty bug." Mary chuckles. "Thank you." Dean sighs glancing past her to see his daughter sitting in the tub. "I've got this handled." Mary says closing the door. Dean sighs and heads to the library. "How's she feeling?" Sam questions. "She's alright. Moms with her." Dean sighs opening his laptop.
Half an hour later.
"Dad? Are you busy?" Mya says from the doorway of the library. "Not at all Sweetheart. What's up?" Dean says closing his laptop. "Can I sleep with you tonight?" She whispers. "Yeah. Come on." Dean says getting up and wrapping an arm around her shoulder. "I'm really sorry I've been so mean today." She whispers into his shoulder. "I know. You should've told me you weren't feeling well." He says a light scold on his lips. "I'm sorry." She whispers. "It's alright. Let's get you in bed." Dean says opening his bedroom door and placing a trashcan beside the bed. "How are you feeling?" He asked as she crawled into his bed. "Better. I'm sorry I threw up everywhere." She whispers as he takes off his shoes and climbs into bed with her. She snuggles into his side immediately. "It's alright Sweetheart." He chuckles.
