Original Description:
 
An older Scootaloo, now named Absentia, was working in the Rainbow Factory and she heard someone knock on the door, came out and saw a baby and took it inside.
 
“Poor thing… Who could leave you out here all alone?” Absentia asked the baby pony. She looked at something in front of her legs, she grabbed the baby pony carefully so she doesn’t wake her up. Absentia saw a piece of paper and picked it up and looked at it and the paper said, “Take good care”.
 
“Take care of her?” Absentia wondered. She looked anywhere and did not see anyone. She decided to do it, after all, she could hardly have any more babies. She asked Rainbow Dash if she could be out for a few days to take care of the baby and Rainbow Dash said, “Yes,” and she knew what to name the baby pony. She named her Sweet.
