A beautiful day in Ponyville. Home to Princess Twilight and her friends.
There goes our little muffin queen's pony counterpart (isn't she cute?).
Let's see what our favorite six ponies are up to at Twilight's new castle.
Rarity's emblem is glowing... What does it mean? (Answer: The six ponies would later sit st their throne emblem and discovered the Cutie Map in episode 92 of Friendship is Magic.)
AJ and Flutters pushing a box. May it contain the mirror? Also, Spike is reading Rainbow Dash's favorite book, Daring Do.
Of course, one simply must not be too clean.
What's wrong, Rarity? Pinkie blowing up a balloon should be nothing new to you.
"Where do you want all these books?"
Pinkie, pretty sure your throne has three balloons on it, not apples.
"Even this one that's glowin' and vibratin'?"
They may not have cell phones in Equestria, but books seem to somehow act like them.
What do you mean by "glowing and vibrating"?
"It looks like a message to Princess Celestia..."
"...from my friends at Canterlot High."
"How is that even possible?"
"...it sounds like they need my help."
That book is about Equestrian's myths and Pony Tales. That's the same storybook seen in the beginning of episode 1 and the second act of episode 90
"The way Sunset Shimmer described them..."
"... I think these new girls sound an awful lot like... the sirens."
"I don't actually know what that is!" Typical Pinkie.
The sirens were three beautiful..."
"...but dangerous creatures..."
"... who had the power to charm ponies with their music."
" But to maintain this power..."
"... they had to feed on the negativity and distrust of others."
"The more of this negative energy they consumed, the stronger their voices became..."
"...and the farther they could spread their dark magic."
"I don't think I like this story very much."
"If the sirens had their way, they would have divided and conquered all of Equestria."
"But a certain Star Swirl the Bearded wasn't having it."
"Rumor has it he found a way to banish them to another world – one where he believed their magic power would be lost"
"That world must have been the one where my Canterlot High friends live."
"But Star Swirl must have sent them there ages ago. How come they're just surfacin' now?"
"I don't know. But if my hunch is right..."
"...and it is the sirens who have come to Canterlot High, this spell they've cast is just the beginning."
"My friends need me. I have to get back to them."
"I hate to burst your bubble, Twilight..."
"...but the connection between their world and Equestria..."
"...will still be totally cut off for a super long time."
"Okay, first of all, if there was bubble-blowing going on..."
"...why wasn't I told about it?!"
"And secondly, if the connection is totally cut off..."
"...how was Sunset Shimmer able to get a message to Twilight?"
Oh, my Celestia! The pink pony has a point!
"Pinkie Pie, you're a genius!"
"Yeah, I get that a lot."
"Now about those bubbles..."
Twilight's preparing to gather things.
Whoa, since when did Twilight made something this technologically advanced since that crazy contraption from episode 15 of Friendship is Magic.
"...and the interval between the two points is defined as the square root of the sum of the squares of the separation between the points along three spatial dimensions."
"She's gonna take the magic in here..."
"...and put it in there."
"That'll make the portal open up so that whenever she wants to..."
"..she can go from here..."
"Now to see if actually works."
"Don't suppose we could join you this time around?"
"It could make things pretty confusing if Canterlot High all of a sudden had two of all of you."
Makes sense, preventing paradoxes and whatnot.
"But I still get to go, right?
"There isn't another one of me at Canterlot High. And you never know if you might need your trusty assistant."
