Mariah is pregnant with her crush's unborn child. She has told Cas or her brothers yet, since the farther along he gets, the bigger she gets.
But she's worried that they'll won't take it well, since the baby is half-human and half-angel ((Only to find out the baby was human when the baby is born, as Castiel didn't have his Angel-Grace when the baby was conceived))
But can't hide it from Cas cause he's an angel he can see it.
