Rarity and Fluttershy have been friends for years, and every week they go to the spa. But after every trip, Rarity finds herself growing greener with envy over Fluttershy's beauty and grace, if not something more than just envy—
After their argument with Fluttershy, Rarity and Pinkie return to Sugarcube Corner in tears. Are they really following pointless pursuits? Rarity decides to stay the night. If they are to be frivolous ponies, can they be frivolous together?
Rarity has been under stress recently from overworking, and Pinkie Pie has noticed. Wanting to make her friend happy again, she suggests taking a break from her constant work. Her solution is easy: A girls night out.
After a long and depressing summer in Baltimare, Rarity returns home. Heartbroken, she looks forward to seeing her dear friend. If anypony can cheer her up, it's Pinkie.
Friends who play together, stay together. That was the philosophy Rarity had in mind when she suggested she and Pinkie play a game of chess every week. Unfortunately for Rarity, however, she finds out that Pinkie is playing more than just one game.
