Okay people, headcanon time. Soarin and Spitfire were in a committed relation ship and decided to have a baby. They called their young pegasus Flash and taught him to fly bravely. One day, when flash was about 12, a visitor came to their house, a brown earth pony with an hourglass cutie mark. He called himself Dr. Hooves, and told the family that he was a time traveler, and that in a few days, Princess Celestia would be in mortal danger, but 25-year-old Flash could save her. On seeing Flash, however, Dr. Hooves had been surprised, because the Flash he saw was only 12. Therefore, he said, Flash must travel back in time and live in the past, so that he would be 25 by the time he needed to save Celestia. Flash agreed, and Dr. Hooves left him in a town near Phillydelphia. Over the years, Flash learned how to be a royal guard and joined the regiment protecting Celestia. Now he waits as the date he will have to save the princess’ life draws closer. He knows when that date will be, but would never tell.
