Rainbow Dash has pulled a muscle in her wing. Not a big deal, until she tries to fly home on it in bad weather and nearly dies. Fluttershy saves her, carries her home, and takes care of her.
Rainbow is Scootaloo's real mother. First problem, she doesn't know that. Second problem, Scootaloo's living in an abusive household after Rainbow gave her up for adoption fearing of what kind of mother she'd be. But now it's time to face her demons.
