The other Primes tell Sam, while he's unconscious, that The Matrix of Leadership is something that you earn and not something that you find. The Matrix reforms and Sam revives Optimus; all of a sudden, The Fallen appears and steals The Matrix in order to activate the device that will consume the sun to create energon. Jetfire gives some of his parts to Optimus so that he can fight The Fallen. Optimus kills The Fallen and Megatron and Starscream escape. Optimus sends out a message and says that the Autobots and humans are united by the past and that they must work together. Sam goes back to his astronomy class.
