Funny. He feels idiotic, not brave.

None of the three shots he gets in before the rock lands hit. On the bright side, he kept himself from using the force. Also? He's about as good as the average stormtrooper.

He scowls at the rock because it has personally offended him. He does not crush it with his mind like he would like to since this is just as much about control as it is learning to use a blaster. "If I used the force, I would be able to hit it blindfolded."
