Starscream blinks in surprise over the fact that someone was actually taking him at his word for once. How unusual. His wings tuck back and he slinks ahead a few steps. "Just one. He had no visible badge but he did identify himself as such. Seemed to have a few wires loose, if you catch my drift. Called himself Sentinel Prime, which is of course, impossible because Sentinel... is..."

He trails off, suddenly putting two and two together now that he understands that there's some time and alternate universe shit happening in this place. "Ah."

He decides that touching upon how he fired on the guy for ignoring him is probably not a good thing to bring up right now.
