Story:
Five years after Spike and Rarity got married, in order to strengthen the alliance between the Dragon and Equine Kingdoms, the elder Dragons call upon an old tradition, which involves two champions from both Kingdoms to be married. While Ember is the obvious choice for the Dragon Kingdom and ends up going to Spike due to him being the only Dragon ever raised among Ponies. While Spike does like Ember, he’s somewhat hesitant at first due to his relationship with Rarity, but she manages to convince him to go through with it, believing that not only will it help Equestria, but also give Spike someone to be with throughout his long lifespan. After agreeing to an open relationship, Spike eventually goes through with it.
Before temporarily leaving for the Dragon Lands, Spike urges Rarity to find someone to “keep her company”, not wanting their open relationship to be one-sided. During that time Rarity went gem-hunting (while Twilight babysat Crystal Clarity and Lavender) and came across Maud in the Diamond Dog Mines, who was inspecting possible fault-lines. Sadly during their search a cave-in forced them to take the long way out, which takes three days. During their journey, Rarity slowly started to see a huge range of emotions behind Maud’s seemingly stoic exterior, while Maud comes to admire Rarity’s eye for detail when they find themselves in a crystal cave, after they exit the cave Rarity thinks back on Spike’s words and asks Maud out on a date…
