This story is a sequel to I Love Ya to the Core

Spike finds himself on a game show hosted by Discord where he has to choose between three mysterious bachelorettes, not realizing that this is a ploy to settle a love triangle he has not been aware of. Who will Spike choose?
Hearts might be broken and secrets might be spilled.
This is a "sort of" follow-up to "Bride of Discord." Not really a sequel, but is set in the same universe.

What if Discord had not been turned to stone by the Mane 6? What if he had escaped?
It is three years later and the Mane 6 have moved on with their lives, all except Fluttershy, who cannot get the draconequus out of her mind. The others are happy in their new and comfortable lives, until their enemy returns and will only relieve Equestria of his havoc in exchange for a bride.

This has been adapted into an audio series.
