The Doctor had left Derpy to take care of something that he worried that Derpy will get hurt on. While they are both broken hearted in leaving. Derpy gives a Pinkie Promise (the ones you HAVE to keep) to wait for the Doctor on a hill where they first met. While the Doctor promises to come back. But they don't expect to be gone for 5 years....

Ditsy Doo or known as Captain D of the royal guard has been stuck in war for 2 and a half years. War that happened when Princess Celestia was killed and Princess Luna got sick and defenses were weakened. It was always up to the Captain now. But when a clot the enters in a blue box comes back the war is suddenly on a new turn. Will the Doctor save Equestria once again? What has happened to Captain D/Derpy? And what will the Doctor do to get her back?

This is my first My Little Pony FanFiction. This is really the only shipping I really support in this show. This IS the Doctor based on the 11th doctor but I am more of a Matt Smith fan then David Tenate. You really don't need to watch Doctor Who to understand this but some jokes will be based off it. I also kinda like to go with things that happened in Doctor Whooves and Assistance from YouTube. So yeah. I hope you enjoy this!
