Optimus Prime, CadeYeager: There remains a price on my head. I endanger you all if I stay.
I shall take the Seed where it can never be found.
Cade Yeager: Will we ever see you again?
Optimus Prime: Cade Yeager, I do not know. But whenever you look to the stars, think of one of them as my soul. Defend this family, Autobots. As they have you. Defend all they can be.
