The cough:As a virus quickly spreads across Equestria, simply by coughing on one another, ponies everywhere are dying within a short amount of time. As a way to escape the virus, the Mane 6 lock themselves in a dark room, boarding up all the windows and doors. However, someone within the room coughs and everyone freaks out, the Mane 6 are now part of a game to find out who was the pony who coughed, whoever was the one who coughed must die before they spread the virus to the other five ponies.
