It's been years since he's last seen you, last seen anyone that he was familiar with. Bumblebee's been rusting away, hiding away with the TRF hunting him down.

He's never been more relieved to hear Optimus's voice through his intercoms. Especially when he sees you with the others. Despite the other Autobots' comments of his 'childishness', he clings to you.

"Lord, thank the heavens!" Bumblebee's radio buzzes. He can't speak, but at that moment, he wished he could tell you he missed you.
