Keep us together one family

Later that evening in Canterlot was Twilight, Moondancer and Spike going back to the abandoned library to get some sleep. None had been used that library for ages since that Twilight had left Canterlot. Later that night had Spike, Moondancer and Twilight been awake. The ponies and Spike they were hearing fillies speaking, but there was no fillies in the library.

"Hey, I wonder who you are." Twilight shouted.

Nopony answered Twilight. The voices of the unseen fillies went on. It felt like ghostly fillies that talked together were around in the library.

"Bloody Mary." a ghostly filly said for a while.

The ponies and Spike could not see who that was. Suddenly were names been writing on the walls, but they disappeared.

"Spike, get your camera." Twilight said to Spike.

Then was Spike taking pictures of the library. The flashes from the camera showed ghostly fillies writing their names of the walls. Some of the ghosts wrote Bloody Mary on the wall too. Some of the fillies sang nursery rhymes. That made the two ponies and Spike move back to Moondancer's house for the remains of the night. The next evening where Twilight using her image spell to chase the ghost fillies away from the library. Twilight had found out that the library was a school at the time of Starswirl the Bearded. After that were Twilight using her undo spell to remove the ghost fillies from the library to not return. That next morning were Twilight, Moondancer and Spike cleaning up the library so it looked like the days that a younger Twilight first used the library a long time before she moved to Ponyville.
