"Scootaloo... YOU ARE A GENIUS!" Dash said.
"Well thanks Dash but I think you are way more of a genius than me!" Scoot said.
"So... When should I do that Sonic Rainboom?" Dash said.
"Well tommorow i could intentionally fall from the clock tower and you could catch me and do your Sonic Rainboom!" Scootaloo said.
"Also who took care of you while I was gone?" Dash asked.
"Oh Fluttershy did" Scoot said.
"Then you really should get back home or else she is going to REALLY freak out!!!! She must be so worried right now!" Dash said.
"Yeah you're right..." Scoot said.
"Well I'll cya tommorow at the tower at noon ok?" Dash said.
"Yep cya sis!" Scoot said, walking away.

The next day... At the top of Ponyville's tower.

"Scoot you're sure you wanna do this?" Dash said.
"120% sure! I would do anything for my big sis! And if I don't no one will." Scoot said.
"Thats very brave of you Scoot, well I'll hide behind that cloud over there and wait for you to jump" Dash said.
"Ok! I'm sure everything will be fine" Scoot said.

5 mins later...

"HEY EVERYPONY I WILL JUMP OF THE TOWER AND FLY!!!!" Scoot said.

Everypony was telling Scoot not to jump but she did anyways and just before she touched the ground Dash came out of nowhere, catched her and did her Sonic Rainboom! Everypony was smiling and started shouting Dash's name and were so happy to see her back.

"Dash how did ya escape the changelings!?" Applejack said.
"What did they do to you exactly? I need to know everything about them!" Twilight said.
"Do you know that some changeling tried to replace you?!" Rarity said.
"Girls calm down! I will answer all of these questions at once... I WASN'T PONYNAPPED BY THE CHANGELINGS!" Dash said.

Everypony looked at each other confused.

"I was here, in Ponyville, all this time!" Dash said.

Everypony seemed even more confused.

"I'M A CHANGELING AND I ALWAYS WAS... I JUST NEVER KNEW!" said Dash shifting into her changeling form.

"Oh my gosh... We... We... Should have listened to you in the first place!" Twilight said.

Everypony apologized to Dash and accepted her the way she is...

The end!
