Optimus' sacrifice (DA)

This is how Optimus and Twilight's sacrifice goes in Dark Awakening.

[Optimus and Twilight get ready to make their sacrifice]

Optimus Prime: Optimus Prime and Princess Twilight Sparkle to Autobot fleet. Return to Cybertron. That is our final command.

Twilight Sparkle: And do not have second thoughts.

[The Autobot fleet heeds their call and return to Cybertron]

Quintesson #1: What?

Quintesson #2: The Autobot fleet is escaping.

Quintesson #3: We have to stop them.

Quintesson #1: And their flagship is on a collision trajectory for the detonator!

Quintesson #3: Direct all firepower on that ship. Obliterate it!

[They fire at the ship]

[The ship remains undamaged]

[The Quintessons watch]

Quintesson #1: It's not stopping.

Quintesson #3: No Autobot or pony could survive that.

[We see Optimus and Twilight]

Optimus Prime: Til All Are One.

Twilight Sparkle: May friendship guide you to the path of heroism.

[The ship explodes with Twilight and Optimus and the Quintessons]

[The explosion makes a nova]

[The Autobot fleet flees]

[We see our heroes seeing the nova]

Kup: Goodbye, old friends.

[Applejack, Pinkie Pie, Rarity, Fluttershy, and Rainbow Dash look on in dismay. Arcee and Wheelie comfort them as Ultra Magnus and Rodimus Prime look out to deep space]

Ultra Magnus: This nova will be their memorial.

Rodimus Prime: I don't know if I'll ever be the leader you two were, but for sure... I'm gonna try.

[The Autobot fleet continues to return to Cybertron and an image of Prime and Twilight wipes in across the stars]

Rodimus Prime: [offscreen] So long, Prime and Twilight.

Narrator: But is this really the end of Optimus Prime and Princess Twilight Sparkle? Find out in tomorrow's exciting episode, The Return of Optimus Prime and Twilight Sparkle.

[A spark appears in the the distance as the episode ends]
