The Right Choice - Part 2 (Johnsonverse)

The Right Choice - Part 2 is the twenty-sixth episode of the sixth season of My Little Pony: Equestria Girls and the one-hundred-and-fifty-second episode overall. It is the second episode of a two-part season finale, following the first part.

In this episode, Sunset Shimmer, realizing that she has made life difficult for her human counterpart, decides to make the ultimate sacrifice by leaving the human world, but she and the Rainbooms are interrupted by a new threat.

The human Dazzlings
After the events of Part 1, the human Sunset reveals to the Rainbooms that she doesn't know where or who her parents are, and that she was left on the doorstep of an orphanage as a baby. The Rainbooms decide to welcome her into their group as a permanent member, and enroll her into Canterlot High. When Principal Celestia and Vice Principal Luna welcome the human Sunset, the Rainbooms celebrate, with Pinkie proposing a special party for the human Sunset's acceptance into the school.

When they exit the building, they see the pony Sunset, who is about to tell the Rainbooms about her decision, but notices a harsh noise coming from her geode. The other Rainbooms notice this as well, and suddenly, they see human versions of the Dazzlings, who are much more cruel than their siren counterparts. The human Adagio reveals that she has tricked the school into siding against them, before arguing with the human Aria about this; the argument ends when the human Adagio threatens Aria. The human Sonata asks when they can get tacos, since it's "Two-Dollar Taco Night", but Adagio tells her they can get tacos after they have the entire school kill the Rainbooms.

Rainbooms vs. human Dazzlings
Rainbow Dash shrugs this off, but notices that Trixie and Starlight Glimmer are carrying baseball bats. Trixie tells Dash that they're not off to play baseball, and reveals that the Rainbooms are surrounded by every student in Canterlot High, including Flash Sentry and even Derpy, all carrying pitchforks, torches or other weapons, with the intent of killing the entire group, starting with the human Sunset. The Rainbooms suddenly pony up with the magic from their geodes, and are about to defeat the Dazzlings, but are rendered helpless when the Dazzlings use their geodes to steal the Rainbooms' magic.

Just then, Princess Twilight enters the human world with her friends, who engage in a battle across the city of Canterlot. She also hands the Rainbooms some magic to help them defeat the human Dazzlings, and the battle continues as they all travel through different dimensions run by different animal species. The human Dazzlings end up being defeated when they end up being mortally wounded, and Princess Twilight, knowing the human Dazzlings won't give up, banishes them to the void.

A final goodbye
After defeating the human Dazzlings, the entire school forgives the Rainbooms and go to their homes, while Princess Twilight and her friends return to the pony world. Sunset tells Princess Twilight through her journal that she's about to leave the human world forever. Princess Twilight warns Sunset that she can no longer write in the journal due to the magic dissipating, but can still read through it.

Sunset calls the Rainbooms together at Canterlot High and announces that she will leave the human world for the final time, and hopes that one day, she can return without dealing with the imbalance. She hugs the Rainbooms, before handing her personal journal and leather jacket to Sci-Twi, making her the new leader of the group. Sci-Twi assures Sunset that there's no way she'd forget, even at old age. Sunset shakes hands with her human counterpart, and hands over her geode. She takes one last look at Canterlot High and Sci-Twi, before walking through the portal. Sci-Twi touches the side of the statue, which does nothing. Upon returning to the pony world, Sunset embraces Princess Twilight, and is welcomed into her group of friends while the Crystal Mirror is deactivated. The episode ends with a brief montage of clips featuring Sunset and her friends from prior Equestria Girls films, specials, and episodes.

Quotes
''"Now, I know there's a human version of myself right there with you guys. But I've made my decision. I decided that I will remain in Equestria. I realized that, in all the time I've been here, I've been taking away someone's life, identity, and existence. It was my desire for power that led me here in the first place, and I've learned so much about friendship, all thanks to you guys, Princess Twilight, and Princess Celestia. Now, that doesn't mean I won't be here again, as I may come back from time to time, but I hope you understand. Twilight, Rainbow Dash, Rarity, Applejack, Pinkie Pie, and Fluttershy, this isn't goodbye, just a farewell." - Sunset Shimmer "That's right, and thanks to you and your Equestrian magic, our quest for power has been impeded for too long. And now that you're about to leave... you and your group will die instead. Right here, right now." - Adagio Dazzle (human) "I'm certainly going to miss you, Sunset Shimmer." - Twilight Sparkle''
