Sci-Twi discovers an analomy
Upon leaving Canterlot High, the Rainbooms ponder on where to go. Sunset suggests going to the Sugarcube Corner to hang out. When they get there, however, Sci-Twi notices a sound coming from her geode. The other Rainbooms hear that same noise coming from their geodes as well. Sunset decides to go to the pony world and ask Princess Twilight Sparkle for answers.

Once Sunset goes through the portal, she sees Princess Twilight, dusting some things in the Castle of Friendship. When she asks Twilight, the latter speculates that the spell Sunset used to enter the human world created an imbalance causing Equestrian magic to spread beyond the human world, and has suspicions that this magic may be displacing a human version of herself. She tells Sunset to stay in Equestria for a while and get to know her friends' pony counterparts.

Another Sunset
When Sunset doesn't come back, the rest of the Rainbooms wonder why she's taking longer than usual. They notice a girl who looks almost like Sunset walking to the spot. Sci-Twi walks over to the girl, asking for her name. She replies that her name is Sunset Shimmer, and the other girls, who heard this, are confused. Just then, Princess Twilight walks in and hands Sci-Twi Sunset's journal, as Sunset was going to stay in the pony world for a while, before noticing the human Sunset. After remarking that it's even stranger than meeting her human counterpart for the first time, Princess Twilight rushes off.

Confused, the Rainbooms meet the human Sunset for the first time. The human Sunset explains that she keeps getting displaced from the human world all the time, and that she has come to expect that. Sci-Twi explains that the girl who handed her the journal was Princess Twilight, before the other Rainbooms explain some of her adventures with them.

Meanwhile, back in the pony world, Princess Twilight confirms to Sunset that there is a human version of herself in this world. She tells Sunset to tell her friends in the journal that she's going to stay in Equestria for a while. The Rainbooms get the message and, with no choice left, decide to start hanging out with the human Sunset.

Making a choice
One day, when hanging out with the Mane Six, Sunset realizes that, all this time, she's made life difficult for her human counterpart, practically taking everything from her, including her life, identity, and even existence. Knowing that it wouldn't be fair to force her human counterpart to live in Equestria to restore the imbalance, and having learned everything about friendship in the human world, she decides to return to the human world to announce her decision.
