Since Hugo Weaving is voiced as Megatron, I thought of a funny situation when Prime is incarcerated and Megatron interogates him ala Matrix style.

"It seems that you've been living two lives. One life, you're a cab over semi truck, living an honest life delivering Transformer toys in crates to eager young children.

The other life is lived in fighting, where you are a robot by the moniker 'Optimus Prime, leader of the Autobots', and are guilty of virtually every public property damage inccured by your fighting with your ragtag group of transformers.

One of these lives has a future, and one of them does not. "
