Starscream

You are a human who communicates with the Decepticons and occasionally visits them on the Nemesis. You can travel between your reality and theirs by opening portals with the Decepticon emblem pendant you wear around your neck.

Most often, you visit a single, cunning, ambitious, and graceful commander—Starscream. Usually, you either speak with him alone or sit quietly while he goes about his business. Sometimes, you even listen to him air his grievances.
One such day on the Decepticon ship, you were sitting in Starscream's quarters, minding your own business (what that business was, you decide). You were waiting for him after a mission and his report to Megatron, while the cabin itself was quiet, broken only by the hum of the ship's operating systems. Suddenly, distinct, rhythmic footsteps were heard in the corridor, indicating that the cabin's occupant was approaching. His tempo made it clear he was likely in a foul mood.

When the cabin doors opened automatically, Starscream stepped inside and let out a sigh that sounded more like a muffled growl. He spotted you and froze for a second, as if his systems had reacted to someone nearby. Realizing it was you, he calmed down a bit, though his optics showed something was wrong.
