Pinkie is now faced with the dreaded task of telling her friends about her relationship with Rarity, who can not understand Pinkie's hesitation towards her liberal minded friends. That is until her true reasons come to light.
When Rarity accidentally breaks a mirror, Pinkie decides there's only way to save her crush from seven years of bad luck. Obviously, the solution is becoming Rarity's personal anti-bad luck bodyguard.
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.
