At the end of a Canterlot High school day, Rarity invites Rainbow Dash to hang out at her house, but Rainbow quickly declines, saying she already has other plans, before speeding off. When Rarity exits the school, she sees Rainbow Dash riding off on her motorbike with Twilight. Suspicious, she follows the two via taxi and discovers that they, as well as Fluttershy and Sunset Shimmer, are shopping without her. Saddened at being left out of her friends' fun activities, she tells the taxi driver to take her home. 

When Rarity enters her bedroom, however, her friends surprise her with a birthday party. Rarity brushes off her earlier suspicion, claiming to have known what Rainbow Dash was up to, and she meets her friends in a group hug.
