Celestia's morning has been difficult enough, between hearing Twilight's confession of love, and then breaking her heart as gently as possible. Mere moments later, her private chambers are rocked by the shockwaves of a time-traveling spell. This marks the arrival of Celestia's alleged lover from five thousand years in the future, Princess Twilight Sparkle—or as she insists on Celestia referring to her, Glitter-Flanks.

Armed with thousands of years of knowledge of which buttons to push and how to make her squirm, Glitter-Flanks has traveled back to this date for one singular purpose: to establish the closed time loop that sets the two of them up as a couple.
