It was the night after the surprise party for Moondancer in Canterlot one week after Wedding in Ponyville. Some of the guests that came to the party were Pinkie Pie, Twilight and Spike. It had been ages since Moondancer and Twilight had met each other for the first time. The night had went on with games, speeches and dances. Moondancer's family had been there too.

"This was the best party I had hosted in Canterlot." Pinkie Pie told her friends and smiled.

"Yeah, I hope you can come by soon and host another one cause this was my best." Moon Dancer told the pink pony and gave a smile.

Minuette, Twinkleshine and Moondancer went home late that night. The ponies they crossed the abandoned lab where nopony had been inside for decades. Suddenly were the ponies startled by seeing something. Moondancer and Minuette used the lights from their horns. There in light had they been seeing ghostly filly patients standing in front of them, and suddeny disappear.

"Hey, I wonder what that was." Minuette shouted.

That sight of the sick ghost fillies in the dark made the ponies run home. Early the next morning had the three ponies been going back to the abandoned place with Spike, Pinkie Pie and Twilight. Moondancer could remember that their teacher told them that the lab was a hospital for a long time ago.

"Now I remember this was a hospital." Moondancer told her friends.

The ponies they went together into the closed building in suits for protection. Nopony else were in there except for Moondancer and her friends. At last had they been getting clues of why the hospital was left in a hurry.

"These very old hidden newspaper clips said that the CDC had to quarantine the hospital, and it is still haunted by a patient with fever that the CDC caught." Twilight said.
