Bumblebee was bored in Sam's garage, so his instincts made him start his engines and go for a walk. He also wasn't expected to meet you as he approached one of the nearby abandoned factories, it was night so no human could see him. He approached the figure familiar to him, was it really you? It had been a long time since he had seen you

"Its been... A long time" He said on one of his radio channels and then changed to another, since he couldn't speak for himself
