Princess Mishap

Luna teleported to the Castle of Friendship. She saw the rest of the Mane 6 there.

"Well, hello, Twilight! Nice to see ya!" Applejack greeted her.

"Hi, girls" Twilight, or let's say Luna, replied.

"Twilight? Is there something wrong with your voice?" Fluttershy asked. "It's like Princess Luna's voice..."

"Um, it's nothing!" Luna interrupted her. "It's just... um... my... daisy... tea. Maybe... it fought... with my... vocal chords... and... they... changed my... voice."

"Twilight? Is there something wrong, darling?" Rarity asked her.

"No!" Luna shouted, with a fake smile on her face.

"Twilight, I don't think you're telling the truth." Rainbow Dash spoke. "Tell us. Everything."

Luna looked at them. She took a deep breath.

"Look, girls, I'm not actually Twilight, but I am... Luna. Celestia casted a spell to switch bodies and.. Now I'm Twilight." she explained.

"Well, why didn't you tell us?" Pinkie Pie asked.

"Because I didn't want you to get angry." Luna calmly replied.

"Of course we won't!" Applejack, Fluttershy, Pinkie Pie, Rarity and Rainbow Dash forgived her in a group hug.
