Twilight Sparkle, Rainbow Dash and others in “Unfinished Business”

Twilight Sparkle

I know how we can save the tree: We have to give it the Elements of Harmony.

Rainbow Dash

Whoa, whoa, whoa! How are we supposed to protect Equestria?! How are we meant to rein Discord in if we can't use the Elements to turn him back to stone?!

Applejack

Twilight... The Elements of Harmony, they would keep us connected no matter what.

Twilight Sparkle

You're right about one thing, Applejack. The Elements of Harmony did bring us together. But it isn't the elements that will keep us connected. It's our friendship. And it's more important and more powerful than any magic. My new role in Equestria may mean I have to take on new responsibilities, and our friendships may be tested, but it will never ever be broken. There's no time to lose. Everypony ready?

Ready!
