A is for Acquiesce

Starscream is well known as a stubborn, willful mech. He has ever fought against control, and he hates being told what to do, or that he's wrong, or that his schemes are in need of rethinking. He recognizes this trait about himself and, lacking the desire to change who he is, embraces it. It's not so much that he goes out of his way to do the opposite of what is dictated, but more that he will always find his own ways, his own means, to get a job done. Self-sufficiency is important to him, and so is independence.

And so, Carrion is always very flattered by the fact that, every so often, his Commander gives in to his requests, or considers his opinion on a plan. Maybe it's the product of centuries of loyalty, and maybe it's just their bond, or maybe- and he'll never say this out loud, never- it's one of the tiny concessions Starscream is willing to make for him, because he's Carrion.
