Set in the town of Ponyville, this short story is an episode-like tale.

Applejack is overjoyed to hear that her filly-hood friend Golden Wonder is moving back to ponyville after several years apart. Big Mac is ecstatic to see Large Fries again (XD) Maris Piper and Granny Smith are together just like old times, and Rocket's even joining the Cutie Mark Crusaders!

But whenever anypony asks why the Potato farmers moved back to Ponyville, they seem intent on avoiding the question. Applejack's fine with that; after all, she's finally reunited with her best friend.

But things don't go to plan. In Applejack's eye, her old friend becomes an enemy. Not only has Golden Wonder stolen her customers, but she can barely believe that her friends have left her too. Why on Equestria would ever they do that? It must have something to do with that weird secret - and Applejack's determined to discover it.

Alone, confused and angry, can Applejack sort things out and report to Princess Celestia having learned a valuable lesson about friendship?
