There it was, that hesitation before he stepped forward: all the indication Megatron needed that this was something Starscream could almost consider it wasn't worth bothering him with, which meant it almost definitely wasn't.

He gave him another censorious once-over, making a point of taking in the signs of injury and battle damage, the physical evidence of his failure on the battlefield. "I have no time for your excuses, Starscream," he growled. "The Autobots were practically handed to you; victory should have been assured, and instead I have lost troops and lost a rare opportunity because you cannot carry out a simple ambush." Megatron had taken a step towards him; two. For all he claimed he had no time for this he certainly wasn't stopping Starscream from making his explanation.
