Princess Celestia has sent an invitation to Twilight Sparkle and friends for a royal Canterlot wedding! While reading off the list of invitees, however, Twilight comes across a certain "Mrs. and Mrs. Dash". Turns out Rainbow Dash and Rarity are a married couple, and have been since before Twilight moved to Ponyville. Twilight never knew this. Hilarity ensues, as well as a few feels.
(AU, where RariDash are, well, married. Some canon events and scenes have been shifted accordingly, to Twilight's increasing confusion.)
