Fanon
This shipping started mostly after Sunset's redemption. But because Princess Twilight started to stop appearing in the EG universe, fans quickly moved over to SciTwiShimmer, as Sunset becomes friends with Twilight's human counterpart while staying in contact with Princess Twilight through a magical message journal. Because some SciTwiShimmer fans call the said ship "SunsetSparkle" as well, it sometimes causes fans to confuse the two ships for one another, along with the fact that Sunset is close with both pony and human Twilight.

On AO3, the ship has 84 fanfics, while FanFiction.net has 49 out of 503 in its My Little Pony (cartoon) category.
