Starlight and Sunburst practicing “magic” together. MLP’s most vanilla ship. Funny thing is their ship floats because their back story doesn’t hold water.
 
She became a super villain because the first pony she ever cared about left her behind when they were foals. Due to how common this “traumatic experience” is and missing exposition, most fans can’t relate to Starlight’s disproportionate reaction. There are likely two possible reasons. Its either she has mental problems… or she really REALLY likes Sunburst. The later fuels the ship.
