If Gunner thought this display would somehow wound Damien's pride, he had miscalculated his ability to rise above pettiness and understand just what buttons needed to be pressed. "We always were out of your league." Though in saying this, no move was made to recover the star which had been thrown to the floor. It was just cloth. It had no value beyond the significance it held while worn by those worth the ideals behind the image.
Patiently, the Commander waited until Gunner scurried off and into his ship. And just as the brute had made himself comfortable and started strapping in was when he made a move. It was barely perceptive from that distance. Not to mention how quick Damien could be with sufficient motivation. But in the time Gunner had blinked upon getting seated, the Commander had not only pulled his pocket cannon free but also fired off a shot directly at his canopy.
It was just the one shot. And while it failed to penetrate the toughened glass, which anyone could have guessed, it was placed exactly in line with Gunner's head. If the glass had been removed or otherwise shaved down to cut back on cost - then he would be a momentarily convulsing corpse by now. This was clearly a threat and a loud one at that.
