-1 month later-

It was a month after apple bloom got her cutie mark. Applejack was with her friends at a picnic. Apple bloom though was board, she had nothing to do. That was until applejack came back from the picnic with a wide grin.

"Hey sugurcube, guess what?" Asked applejack

"I don't know. Pinkie did somethin'?" Answered apple bloom

"Well no, but pinkie is always doing something. But we are invited to ah wedding!" Exclaimed applejack

"Ah wedding? That doesn't sound so exciting." Said apple bloom.

"That's just it! But not any old wedding! It's a wedding for ah princess!" Exclaimed applejack

"OK. That still doesn't sound so exciting aswell, but why are you so excited? It's gonna be a few months, a few days at least for it to be ready?" Asked apple bloom

"Now listen here, it's not gonna be long, as it's happening tommarow!" Exclaimed applejack

"Wait, tommarow! We gotta pack our things now!" Exclaimed apple bloom in a panic

Applejack hadn't thought of that. Her mind was still fixated on that she was invited to a wedding.

"Wait ah hadn't thought of that! We need to get to packing now!" Exclaimed applejack

The train ride was chaotic yet peaceful. Apple bloom didn't pack much. Just some scrap metal, a tazer, and a fidget toy she created. Thought flowed through her mind, like how does a gramophone work, and can it be upgraded? Could it be compacted?

However, before she could spiral into inventor possibility, a magic barrier passes her by. Now she doesn't know a lot about canterlot, but she knew there was no magic barrier surrounding canterlot.

"Well that is new." Applejack said, as the last she was their, there wasn't a big force field surrounding all of canterlot.

Apple bloom thought it was strange, why was there a force field during a wedding, unfortunately. She didn't have any answers so she went back into her thoughts.

It wasn't long until the train stopped at the destination, as everypony went there separate ways, apple bloom went to her room to find her bed. Fortunately she found it easily. But what she wasn't expecting was How fancy everything looked. And apple bloom didn't like it, she was used to her workshop/bedroom that this was unacceptable. So she began working on the table in the room, "maybe i could implement my idea on compacted music!" Wonderd apple bloom aloud.

-4 hours later-

Apple bloom was happy. She managed to do it! It was small and could play music well, she even managed to create some sort of small speakers that would go directly into the ear!

Apple bloom sighed as she looked at the clock. "Wait, it's almost TIME FOR THE PREPARATIONS!" Exclaimed apple bloom as she had no idea she was here for so long. So she hurried to pack her tazer and ran.

Apple bloom was reaching her goal when she saw the door open, thinking quickly she hid. What she saw was cadence and shining armor, apple bloom sighed as it was just those two. However before Apple bloom left her hiding place she saw cadence messing with shining head. Now this freaked Apple bloom out as ponies normally don't do that.

Apple bloom sufficiently freaked out she left to do some investigating.

Apple bloom snuck through the halls, looking for any suspicious activities. A few minutes later her search came up with something, a neon green flash that looked like fire in one of the rooms.

Sneaking up and looking through as quietly as possible, she saw a weird bug pony communicating with another bug pony through some green goop.

Apple bloom now knowing something was definitely going to go wrong, she snuck into preparations right as twilight accused cadence of being evil. At this point Apple bloom believes twilight, but her friends doesn't thing so and leaves twilight.

Apple bloom was about to comfort twilight when cadence enters with a look on her face. Apple bloom decides to stay hidden and saw what happened next.

She saw this 'cadence' light a green fire portal under twilight, the same fire she noticed with the bug ponies.

Now armed with this knowledge, she decides to try and find twilight to inform her that cadence might be an insect this entire time.

Ot took almost 30 minutes to find twilight. It turns out twilight was stuffed under canterlot in a cave system, also aperently cadence is a pony and something called a 'changeling' replaced her.

We were nearing the doors when we were stopped by some gaurds.

"Halt, none may pase in the moment, the wedding between cadence and shining is taking affect." One of the guards said

"Move! We don't have time! Said twilight in a hurry

"Sorry mam, but it's the princesses orders." The other gaurd said, it was this moment I noticed an unnatural shine to his coat. So noting what I knew of bugs, I used a bottle of bug repellent.

"Oh what is that stench, wait IT BURNS, AHHHHHhhh" the gaurd on the right Yelled as the other gaurd tried to keep up.

"An' that's why I always keep bug spray on me at all times." Commented apple bloom as she got ready for the plan up ahead.

'My plan was flawless, fool everypony into I was cadence, trap the real cadence away, trap anypony that got too close and vuala, the perfect plan, and soon I will rule all of equestria. Just need to marry this fool and then subjugate the princesses like what I did with cadence, the-'

'Cadences' thought process was interrupted by the door being blasted open, revealing twilight.

"Stop it now!" Exclaimed twilight as she blasted the door open

"Are you so obsessed with with your brother that you would ruin my special day." Fake sobed the appropriate fake cadence.

"Your special day? No its supposed to be my special day!" Answered the real cadence as questions were aroused by many ponies. "She is a changeling, a creature that will replace your loved ones and take your love until you are nothing."

"Oh how astute of you, no matter I suppose I should introduce myself. My name is chrysalis queen of the changelings." Said the now undisguised changeling, looming over the the ponies. "And with shining armors sheild active over canterlot, you can't escape. Haaahahaha!" Chrysalis laughed as changelings all over canterlot undisguised, preparing for a take over, as the hidden apple bloom set her sights on chrysalis, aiming her tazer and fired...
