After the events of the Royal Wedding, Rainbow Dash seeks the company of Fluttershy on the train ride home. Whether to seek proper closure, or just to be near her, isn't quite clear. As they gaze out the window to the rolling landscape of the night, the two Pegasi best friends have a time for their introspection of aspects of the recent past. An introspection into dealing with certain feelings they may have.
Rainbow Dash has come to a recent revelation, and has finally accepted it. Fluttershy is yet to be sure and if she accepts it. Yet, undeniably, something lingers.
