------------------______________Ponyville- 2 years after Luna's return______________------------------

Ponyville was so peaceful, Twilight walked to the meadow next to the village with her 'friends' and her assistant, Spike. The young drake was her result of the test to go to the Gifted Unicorn School, with that achievement, she became the princess's personal student. They had studied together, until the 1000th Summer Sun Celebration, the princess sent her to Ponyville, and with the help of her new 'friends, they managed to save Luna.

After the event, she was allowed to stay in Ponyville in order to stay with her friends and learn more about friendship power. Thanks to the strong bond of friendship, they managed to defeat Discord and became the savior of all Equestria. But the thing that the five other ponies didn't know that their bookworm friend is only a spy, and is secretly informing her mother of everything that is happening in Equestria

The group played together then had a picnic with each other. Until they received a letter from the Princess of the Sun via spike’s fire breath magic, opened it, and to their surprise. Her 'brother' was getting married

"What, my brother is going to get married.?" Shouted Twilight.

"So that means I can organize a party, right? I'm so excited" Asked Pinkie Pie excitedly.

"Calm down, sugarcube everything will be alright, we don't know who your brother is going to marry yet." Said Apple Jack as the other nodded.

"So, are we going to Canterlot now?." Asked Rarity hopefully.

"Yeah, I think so." Answered Rainbow Dash

"In my opinion, I think we should go back home and prepare. I still need to tell my animals about my absence." Said Fluttershy

"Yeah, Fluttershy was right, we haven't prepared anything yet. Let's go home and prepare then we will start going to Canterlot tomorrow." Reasoned Twilight to go back to the library

The group went back to their home and prepare. They tried their best to finish as soon as they can.

------------------______________Golden Oak Library______________------------------

Twilight went upstairs, already warned the dragon not to bother her. Locked the door, and pulled the bugs out from under the bed, used her magic, the bug created a magic circle in which she could contact her mother.

"Daughter? I'm surprised that you are contacting me at this time, you shouldn't do that right now, you would have trouble if someone found you talking with me."

"It's ok, mom, my dragon won't bother me. I have important news for you today."

"Oh, what news are you going to tell me? You already find a good occasion?." The queen asked excitedly

"Yes, mother, my 'brother' is going to have a wedding, but the special thing is his bride is a royalty." Answered the princess with a smile on her face.

"So you want me to aid you, right?" Chrysalis got a nod from her daughter." So what is your plan, daughter?.

"I think you should disguise yourself as that princess, mother. If anyone found out you are acting strangely, you could say that was because of stress."

"Good idea, daughter. Tonight, I'll intrude on the castle, I will meet you at the castle tomorrow."

The princess bid goodbye to her mother hoped nothing would stop them. If their plan failed, they could have many problems.

------------------______________Canterlot Castle______________------------------

The group already arrived at the castle after hours on the train. The guard led them to the castle which was fully covered by the shield. Twilight's 'friends' already divided into many places due to the guard information. Walking around the castle, she realized that her brother was upstairs. Teleport next to him, she tackled the white unicorn to the floor.

"Hey Twily, I haven't expected you here. Can you get off of me?." Asked Shining Armor as her sister stood up.

"Brother, why didn't you tell me about your marriage, especially the one I don't even know."

"Twily, sorry I haven't told you about this. But the bride was your babysitter, Cadance."

"Cady? My old foalsitter? Oh my gosh, I haven't met her for years." The changeling 'excitedly' jumped around her brother

'Look like no one noticed my mother was here.' Thought Twilight

"I hope I wasn't bothering you two." A familiar voice raised behind Twilight as she turned and realized who was the owner of that voice

"Cady, it's me Twilight." Blinked Twilight to the love princess then turned to her 'brother' "Shiny, I want to talk to 'Cadence' for a while, don't disturb us when we talk, please.?"

"Ok, Twily, I'll be here whenever you two done talking." Happily answered Shining Armor.

------------------______________Cadence's personal chamber ______________------------------

Both of them were inside the room, with the door locked and the guards already warned, they dropped their disguises.

"Daughter, I heard your 'friends' are here right?" Asked Chrysalis for sure.

"Yes, mother. They are the other bearers of the elements beside me."

"Good to hear, I have a mission for you. You will take those jewelry" Pointed the queen to a box." and then hide those in your friends' rooms. I'll tell the princess to find them and check their rooms, then they will be arrested for stealing my jewelry. Is it clear, my dear daughter?." Asked Chrysalis 'sweetly'.

"Crystal, mother. But I will have an appointment tonight, I think that will be a good time for me, can you disguise as myself, I'll go to their room and hide the jewelry." The queen nodded in agreement.

"I think we should go back now. We shouldn't let anypony here doubt us for talking so long."

They put on their disguise and exited the room. 'Cadence' headed to her 'brother' and Twilight went to check on her 'friend'.

------------------______________Canterlot Court-1 day later after arrival ______________------------------

The plan worked, her friend was doubted as the princess' jewelry thief. Twilight 'tried' to 'help' her 'friends' but her words still didn't work. The five ponies were banned from the wedding, Twilight and Chrysalis were happy about it. The group left the Castle and back to Ponyville in regret, without knowing the mastermind of the plan.

Twilight walked through the hallway along with her mother, they had removed their best threats. Tomorrow, the wedding would be organized, her plan would finally succeed after years spied on the ruler. The changeling queen and princess headed back to Cadance's chamber while talked about the wedding so as not to be doubted by the ponies.

With the captain of the royal guards under her control and the real princess inside the crystal mine, Invaded Equestria would be only a matter of time.

------------------______________Royal wedding ______________------------------

Stood in the podium was the captain of the royal guards, Shining Armor, fully controlled, next to him was Twilight. 'Cadance' walked to the room, wore a dress made by a new fashioner who was invited yesterday after Twilight's friends were banned. Made her way to the podium, opposite the captain.

"Dear mares and gentle colts, we gather here today to ..." Celestia's voice stopped abruptly when a new but familiar voice rang through the room, the owner was no one else but Luna.

"STOP, ponies run away from that princess, she is a changeling who trying to feed on the love of the captain here." Shouted Luna to the fake princess with the real Cadence behind her back.

"Right you are, Princess. As a queen of the changelings, it is my duty to keep my changelings strong and fully fed." Laughed 'Cadance' she dropped her disguise reveal her true identity, Queen Chrysalis "My plan was to conquer this kingdom and it nearly worked until you appear." The changeling smirked "But that still doesn't change the situation, the bearers were banned from the wedding so they would never come here in time."

"Really? So you were the one who blamed us for stealing your jewelry." Said Rainbow Dash angrily as she tried to punch Chrysalis on her face but was held back by the queen's magic.

"I haven't thought you would be here, but you wouldn't win against me, I have prepared for years."

"Twilight, you should go get the Elements with your friends, I'll stop her." Said Celestia.

'Twilight, go with them and acted like you got caught, my changelings will get you back here.' Said Chrysalis in the hive mind as she shot a beam to the pony princess

Twilight nodded to her 'friends' and ran out of the room. Meanwhile, the changelings crashed to the shield to aid their queen and princess. After the changeling princess ran out of the castle, the shield began to crack and collapse. Some changelings landed at the castle to help their queen. The others flew to the direction Twilight was running as the queen command. The changelings then crowded in front of the element storage, stopped her 'friends' from getting what they wanted. The crowd began to change into the element bearers, tried to distract them for a while, as the fight went on, the bearers lost. Twilight was led to the castle again and the other to the dungeon.

Dropping her pony disguise, she entered the cemetery hall. The view inside it satisfied her, Celestia was wrapped in the cocoon, Luna's, Cadance's horns and hoofs were stuck in changeling's slime. Her presence got Luna's attention.

"Twilight? So you were a changeling all the time? Look like I was so wrong. I thought I could trust you, I thought you were my friend, I even bring myself to love you, li-like a lover, but I was wrong." Cried Luna in disappointment
