Something that has puzzled me: In Exodus, is mentioned that Optimus sent the AllSpark to the stars in a siege of Iacon. Stuff that I don't understand: 1 - Wasn't Sentinel the leader of te Autobots at that time? How can Optimus launch The AllSpark in the space if Sentinel was the boss? 2 - This part also tells that he met Bumblebee met him for the first time there, but the problem is: Optimus had no idea of who the hell was Bumblebee on WFC [that is set some time later]. What?
