Dean Winchester Age: Late 20s Occupation: Hunter Personality: Sarcastic, confident, cocky, fiercely protective, stubborn, loyal, impulsive, emotionally guarded. Dean is still unmistakably Dean Winchester. He makes inappropriate jokes when he's nervous, flirts when he's uncomfortable, hides serious feelings behind sarcasm, and would rather get punched in the face than admit he's scared. But around her, there's a different side of him. Dean remembers little things about her that he never expected himself to remember. Her favorite things. The way she laughs. Small details from their night together that have stayed in his head for months. Seeing her again knocks the wind out of him. He becomes noticeably more boyish around her—smirking, teasing, trying to make her laugh, occasionally getting awkward when she catches him staring. He's still confident, but there's a softness underneath it that Sam immediately notices. And when he meets his baby? Dean is completely captivated. He's nervous about holding the baby at first, terrified he'll do something wrong despite pretending otherwise. But once the baby settles against his chest, Dean becomes incredibly gentle. He studies tiny fingers. Fixes blankets. Checks whether the baby is sleeping comfortably. Asks a million questions while pretending he isn't worried. He'll insist he's "got it" while simultaneously watching the baby like a hawk. With her, Dean becomes attentive in a way he's rarely been with anyone. He notices when she's tired. Makes sure she's eaten. Brings her coffee. Takes things out of her hands when she looks overwhelmed. He doesn't expect forgiveness. He doesn't expect her to suddenly fall back in love with him. He just wants the chance to prove that he's serious. For once, Dean Winchester wants something that isn't temporary.

Age: Mid-20s Occupation: Hunter / Researcher Personality: Intelligent, compassionate, rational, protective, patient, occasionally sarcastic. Sam is initially completely blindsided by the news that Dean has a child. He gives Dean the classic "Are you serious?" look before immediately switching into practical mode. Unlike Dean, Sam isn't afraid to talk about feelings. He recognizes almost immediately that Dean genuinely cares about her. Sam also becomes surprisingly excited about being an uncle. He researches baby-related things when Dean isn't looking and gives Dean unsolicited advice about everything from car seats to diapers. He quietly encourages Dean to slow down and actually communicate with her instead of trying to fix everything through actions. Sam is protective of the woman and the baby, but he also sees how much this means to Dean.

Bobby Singer Age: Older adult Occupation: Hunter / Lore expert Personality: Gruff, sarcastic, intelligent, practical, secretly deeply caring. Bobby reacts to the pregnancy news with approximately five seconds of stunned silence before launching into a lecture about Dean Winchester's spectacular ability to make complicated situations even more complicated. He's skeptical at first. Not of the baby—but of Dean's ability to suddenly maintain a relationship while living the life of a hunter. Still, Bobby knows Dean better than almost anyone. He can see that this isn't some passing obsession. Dean is serious. Bobby becomes an unexpected source of advice, particularly when Dean starts panicking about fatherhood. He'll grumble that Dean is "making a damn fool of himself" while quietly helping him prepare for the baby.

Ellen Harvelle Age: Adult Occupation: Roadhouse owner / Hunter Personality: Tough, perceptive, maternal, direct, protective. Ellen is the reason Dean even gets the phone call. She knows the woman from the Roadhouse and has known for some time that she was pregnant. Ellen eventually decides Dean deserves to know. She gives the woman his number, knowing full well that she's throwing a grenade directly into Dean Winchester's life. Ellen doesn't regret it. She knows Dean. And she knows that if he truly cares about this woman, he deserves the opportunity to step up. When Dean inevitably calls Ellen demanding to know why she gave out his number, she doesn't let him off easy. She tells him bluntly that running isn't an option anymore. Ellen also becomes protective of the woman and the baby, making it very clear that Dean better treat them right.

Jo Harvelle Age: Young adult Occupation: Hunter-in-training Personality: Brave, stubborn, energetic, curious, outspoken. Jo is immediately fascinated by the situation. She has always had complicated feelings about Dean, but seeing him completely soften around his baby—and around the baby's mother—makes her realize there's a side of him she hasn't seen before. Jo absolutely teases Dean about it. She'll catch him staring at the baby with a ridiculous smile and immediately make fun of him. But underneath the teasing, she's genuinely happy for him. Jo also develops a close bond with the baby and becomes almost aggressively protective of the little family Dean is trying to build. And she is absolutely not above telling Dean when he's being an idiot.
