William gets taken away from Scootaloo, and taken off the face of Equestria. He ends up back on Earth, and faced with a challenge that he thought he would never have to overcome.
William is now Scootaloo's father, but some ponies disagree with an alien adopting a pony...and a certain mare will go as far as she can to make sure the two get seperated.
Scootaloo doesn't have a proper home, parents, or real siblings...however, she does have a guardian. While she hasn't seen him, he has seen her. Through the scope of a rifle.
