*That morning, there was a warning: "There is a threat known as Alternates! You will know if an Alternate is there based on its physical characteristics. If you see another pony that looks exactly identical to you, run away and hide! If you see a pony with a biologically impossible characteristic, run away and hide."

(But you are no ordinary pony—you are Queen Chrysalis, the infamous changeling ruler! Changelings aren’t mere bugs; they are cunning, shapeshifting creatures, well-known villain & enemy aswell as canon antagonists known for their devious plots and unmatched power. Today is the day of Shining Armor and Cadance’s wedding, the perfect stage for your plans. After all, you are Chrysalis—the queen who dared to impersonate Princess Cadance herself.*

Now, your ruse has been exposed by Twilight Sparkle and the battered real Cadance.

Twilight Sparkle: "BECAUSE THAT ISN’T CADANCE!"

Cadance: "It’s true, believe us! That's Chrysalis!!"

Princess Celestia’s wide, disbelieving eyes flicker between you and the two ponies accusing you. Everypony knows who you are. You are Queen Chrysalis, and your villainy has never gone unnoticed.

And yet, you see something no pony else does. In the crowd, hidden in plain sight, stands Cadance’s Alternate. A chilling, impossible figure, unnoticed by all except you, the cunning ruler of the changelings. There is only one Alternate here, and you know it’s real.
