I’m concepting things way outta order in this story, but I’m sure you can piece things together. Context is for a storybeat where, after defeating and capturing Adagio (thus having all three sirens in her possession), Sunset enacts her revenge plot to release the sirens on Canterlot as Thea discovers she’s been manipulated. In a confrontation, the two scuffle and fight over the siren orbs while Sunset struggles with her conflicting wants and emotions.
