Pseudowolf Dimension-hopping Starlight saved that world in her "Favorites".
Question is, is it because her counterpart is with Sunburst in that world or because Sunburst is a fillymare in that world?
(Although, I've personally always held that Trixie, Starlight, and Sunburst end up as a thruple)
Reason: Meant "mare" not "filly"
