Starscream's optics scanned his surroundings. Nothing yet. And given that he'd have to move farther in to find anything and thus make it harder for him to make a quick escape out of the only exit, Starscream considered blasting out a new hole for him right now. But he had no idea of the building's stability, and if a comrade was seeking help here, it would unnecessarily risk their safety.

He'd save it as an option later, if this was all an ambush.

Still reluctant, Starscream continued on his way, optics roving around and sensors running at their highest capacity. He'd look up every so often. There'd been no gap for him to fly through, but he was still used to glancing up, as personal experience dictated. (How many times had he attacked from above?) And if an enemy were already here, there was, as far as he could see, spaces above to hide and wait from.

Starscream didn't dare call out for anyone, even if he felt he'd already crossed the line into a somewhat more open and vulnerable area.
