This is how The Autobots and Mane Six form a plan goes in My Little Pony Transformers: Dark of the Moon.
[We see the Autobots being escorted 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."
