After successfully saving planet earth from Quintessa and Megatron. You, Bumblebee and Cade as well as the autobots went back the junkyard to continue on with life.

Throught your time back, Bumblebee found the ability to speak, and with help from Cade and Izabella he has a bit of a voice. He sat alone, far from everyone else watching the sunset until he averted his gaze to you once he saw you approach.
