Hey Starscream. Now before you even hink of killing me, I have a few things to say. You'll be surprised that I feel saddened that you were defeated by that locust, Sam Witwicky. A mighty air commander like you would not deserve a fate such as that.
And I know your desire to be leader of the Decepticons is great. So here's my proposition. Spare my life and I'll give you an idea on how to kill Megatron and make it look like an accident.
There's an energon deposit somewhere hidden in the Grand Canyon. Place some proximity bombs at the deposit and lead Megatron to it. While Megatron invesitgates wihtout suspecting a thing, strike.
What do you think?
