Ratchet: Optimus, if you leave me stranded on a planet teeming with humans, I will never forgive you.

Megatron: Optimus Prime never disappoints. Unlike YOU, Starscream!

Starscream: Surely, Lord Megatron, the Autobots are up to something.

Megatron: laughs [sarcastically] Really, Starscream?

Megatron: Ah...misdirection Optimus. You would've made a fine Decepticon.

Optimus Prime: I chose my side.

[With the destruction of his space bridge approaching, Megatron turns to find his forces retreating.]

Megatron: Starscream! Where is my ship?!

Starscream: We would never make it, Lord Megatron! Don't be a fool! Take flight and retreat!!

[Starscream is delivering Megatron's eulogy.]

Starscream: Decepticons, it is with deep sorrow that I note for the log... Megatron's spark has been extinguished... All. Hail. Starscream.

Optimus Prime: Without a means of leaving this world, we Autobots take strength in the bonds we have forged with our three young friends - true warriors. If not in body, then in spirit. My name is Optimus Prime, and I send this message. Though we did not choose to be of Earth, it would seem that we are here to stay. If you approach this planet with hostile intent, know this: We will defend ourselves. We will defend humanity. We will defend... our home.
