By sheer chance, Hitch discovers that Sparky's egg came with a note. Upon reading it, he discovers a familiar name as the author of the note: Spike.
Once informed of this discovery, Sunny realizes that Spike must know what happened to Equestria that caused the pony tribes to become divided. She subsequently recruits all of her friends to join her on a journey to see the old dragon.
When the five mares finally do meet with Spike, they'll be surprised to learn his reason behind sending Sparky to Maretime Bay. And Spike will shed light on how the utopia Princess Twilight created came undone.
