It takes a little bit for Starscream to even move after his rather disgraceful landing. Not out of actual immobility or pain, but from being rather shell shocked over what just happened. He's still trying to process it.

It could probably be taken as a very concerning sign that even when he does move, he doesn't say a word. Even as he slowly gathers himself up to crouch on his hands and knees, he just glowers furiously at the spot where Megatron was standing moments before.

He's going to kill that bastard one day.
