Gaarl growls something to the effect of, "Not if I blast them first or they hit a rock." For all his enlightenment, Zideyl was still just like his slaver kin when it came to brash arrogance. The only reason the wookiee didn't actively wish for the empire to take him down a peg was the self-interest of flying in the same craft.
Running at full speed, fur flying afterward, Gaarl flings himself bodily down the tunnel to the ion cannon turret. The heavy weapon is too slow to take out any of the TIEs without luck, and not powerful enough to score any real damage against an Interdictor. He might try a few pot shots, but for the most part his brain was already working on the puzzle of where best to target an Action VI.
