[The Mane Six watch as they are escorted to their ship]

Twilight Sparkle: But Optimus, we're friends.

Optimus Prime: You are my best friend, Twilight. You always will be. But your leaders have spoken. From here, the fight will be your own.

Twilight Sparkle: I'll miss you Optimus.

Optimus Prime: And I will miss you.

[Optimus sees Bumblebee]

Optimus Prime: Make it short. We're getting ready.

Leadfoot: All right, hustle up!

Bumblebee: When we do whatever we can. Make it like a bow. You will always be my best friend, Rarity.

Rarity: I don't understand why Celestia would even allow this.

[We see Rarity and Discord watching the ship]

Discord: Years from now they're gonna ask, "Where were you when they took over the planet?" We'd just say, "We just stood by and watched."
