Fifteen years after the Cutie Mark Crusaders earned their cutie marks, Scootaloo, now a Wonderbolt, realizes she hasn't contacted her friends in years, despite the fact that she promised to. Desperate to see them again, she sends Sweetie Belle and Apple Bloom a letter telling them to meet her at the old clubhouse. Once there, the three reflect on times long gone.
