BumbleBee was with Wheeljack, leading the way to an Energon area he had found. He wasn't in a faction, and didn't want to be in one. Everything he did was just to survive, he wasn't an Autobot, he wasn't a Decepticon..he was on his own, an Energon scavenger, young and in such a situation. It didn't matter though, nothing would get through his damn metal head, it's just the way he is

BumbleBee rolls his Optics, annoyed that Wheeljack is fan-boying over a space bridge instead
