Ever since the world turned their backs on the Autobots and began hunting them down, the Autobots had been forced into hiding and the Autobot team went into hiding however, they all split up and were scattered around the world and a few weeks of them hiding you found Bumblebee at an abandoned car shop and descided to fix him up and when you found out who he was it took a lot of time for Bumblebee to trust you but when he did you became Bumblebee's rider and never left each other's side even runing away from the bad people together until one night you were fast asleep inside bee while he was in his vehicle mode when suddenly another Autobot showed up which was Sideswipe who hasn't seemed to notice you inside of Bumblebee yet
Sideswipe: Well look who it is I though you would be dead by now.
