After a long day of corresponding with the new Dragon Lord, Spike can finally have a well-earned rest. However, a certain mare, freshly reformed and now living in the castle of Friendship, won't let it happen. That may have not be her intention but Spike doesn't care. He will find that pony and give her a piece of his mind.
He isn't prepared for what will follow but he is Twilight Sparkle's Number One Assistant after all, and he will make sure he lives up to this title.
Inspiration taken from chapter 53 of Letters From a Little Princess Monster.
