Arcee stares back up at Starscream, optics cold and blazing. "You think I don't know the Autobots haven't had to get their hands dirty? You think I don't understand war, Starscream? The difference between the Autobots and the Decepticons is that the Autobots still fight for liberty -- that our leader still believes in the sanctity of life -- whereas yours -- well, all Megatron cares about these days is power. You can try all you like to bring us down to your level, Starscream, but the truth is that if Optimus Prime were willing to throw away half as many lives as Megatron is just to win, he'd have ended the war a long, long time ago. But unlike your precious leader, Optimus never lost sight of what he was fighting for in the first place."
