Shining Armor and Princess Cadence danced together at their first Canterlot academy prom one night in the early 1980s. The ponies danced along to the disco hits at that time. But suddenly had Shining Armor seen somepony that also looked just like Princess Cadenece at the prom.

"Hey, I wonder if you just saw that one that looked like you." Shining Armor told Princess Cadence.

"I don't see anything unusual." the alicorn told the unicorn.

But the alicorn lookalike had been vanished that night. The days passed in the busy Canterlot, where ponies prepared for Equestri's biggest Wedding with Shining Armor and Princess Cadence in April 1984. That news about the Wedding spread all over Equestria in the Foal Free Press and on. Still Shining Armor noticed that alicorn, and she looked like his coming bride just more evil. The pair asked others in Canterlot if they knew about that mysterious mare. Some said it could be a Changeling.

"But Changelings from the clone lake in the Everfree forest only exists in tales." Shining Armor said to Princess Cadence.

"I remember these old stories from our uncle, and I think that some is going to fool us at the Wedding." Princess Cadence said to Shining Armor.

It were the final day before the Wedding. The Canterlot guards looked for the copy of Princess Cadence from the mines to the mountains, but they could not find her. Shining Armor made a huge pink protective shiny and clear bubble with a magic laser from his horn that covered all of Canterlot. Even while the big stallion were afraid of the huge balloon like bubble, were he having a major hornboner too. The playful stallion felt the force from the soft clear, and shiny bubble in his bulge on his head. Shining Armor were together with the alicorn in his room the evening before the Wedding. The alicorn healed the stallion that used all of his powers to keep the huge bubble inflated with his magic horn. But Princess Cadence were under the mines, as the mare that hypnotized the stallion were the Changeling queen from the clone lake.

"You have to tell me where my real princess are." Shining Armor told the Changeling.

"She is under the mines, so I marry you tomorrow instead." the alicorn in disguise said to the stallion.

That next morning had the Wedding for Princess Cadence and Shining Armor finally arrived. But the Changeling from the clone lake army had also been gathered in the mountains above Canterlot. Next Chapter: Hearts strong as horses Estimated time remaining: 32 Minutes
