It starts out as just another train ride for Coco Pommel. While she does thoroughly enjoy managing the Rarity For You shop on Bridle Way, it does tend to involve a lot of travel between the boutiques.
Few things are as boring and as unproductive as train rides, especially if you are the socially awkward type.

This time however she finds herself herself sharing a compartment with somepony who is even more bored than her. After catching him wanking off she decides to teach him a lesson, but they both end up learning something new about themselves.
