Twilight and her cow counterpart are both inside this world’s Friendship Castle's Library.
Inside, mostly (okay pretty much) every book is pulled from the shelves, every scroll unrolled, and well, the whole room looks like what two eggheads would make it look like.
If you’re wondering, the rest of Pony Twilight's friends decided to go with their other world’s counterparts.
Applejack went with hers to Sweet Apple Orchard. (Orchard in this world.)
Rainbow Dash with hers to see how exactly the weather here works.
Rarity going with hers to check up and see what this world’s fashion is like.
And Pinkie and Fluttershy both going with theirs to just check out everything.
Back to Twilight(s), the two creatures going over everything they could find to figure out exactly how they could get enough magic for the spell to work.
“Got anything?” Pony Twilight asks, sounding defeated.
“Yyes!” Cow Twilight brings to her a book, opened to a page explaining about a magic artifact that could help them out.
“It’s called the ‘Alicow Amulet’. With it anycreature can harness enough magic to have the same, if not more, than Celestia and Luna themselves.” Cow Twilight gives a big dorky smile.
“The Alicow Amulet?”
“Yes! You know what I’m talking about?”
Twilight gets up, walking around the room. “Well, to be frank, in our world, it was called the 'Alicorn Amulet'. And also, it's just, in our world, a pony found and tried to used it against me. Not only me, but my friends. And also our whole town of Ponyville."
Cow Twilight deflates just a little bit. “Oh. Well if it bothers you that much, then we can try something else," She looks up at a huge stack of books still ready yet to be read, “I’m sure we’re find something else in all these.” She points a hoof at them all.
“No no, I’m good. Besides, this could be our only chance. Does your book mention where we can find it?” Pony Twilight walks back to her counterpart and also the huge stack of books.
Cow Twilight flips through a few pages. “Yes, and no. According to paragraph twelve, sentence seven, it says that the amulet is actually right in Canterlot, locked up tight in Celestia’s Castle.
“That’s wonderful news!” Pony Twilight says a little pleased.
“Though, bad news is, the Castle is heavily guarded this time of year, and both of our princesses right now are out of the country for a big diplomatic meeting.
“Oh.”
(Back in the EQG World)
“Hey you!” Sunset Shimmer yells over to Terry Astro (A.K.A. the human Toras) from across the street.
Terry Astro looks up from what’s happening to the necklace in his hand to see all seven of the 'Equestria Girls'. The sight of them all making him not think twice as he quickly puts the necklace into his pocket before making a break for it.
“They always have to make this hard, don’t they.” Rainbow said as they all start to run after him.
