Starscream yelps; most of the shots go right up in front of his face, and though they miss, the noise and the proximity startles him. One of the shots, however, catches him right in the shoulder for the arm that he's about to try and gore her with, and that in combination with his panicked state leads him to react by winding up and flinging her as hard as he can at the ground a few feet away. He sends a missile chasing after her, just for good measure, expression contorted in a vicious snarl.
