On later reflection, Bruce thought it would be nice if he had done something cool, or at least cursed at the monster or something. Instead, his first reaction was a kind of wordless scream of shock and fear, as Helia jumped in front of him. 

His screaming evolved into a lot of [color=0072bc]"Got dang,"[/color] and [color=0072bc]"Whoa man!"[/color] as he picked up rocks from the ground, and began to hurl them over-hand at the guard creatures. He made a point to aim over Helia's shoulder, but he was a good deal taller than her and this wasn't difficult. 

After the first two rocks, Bruce realized that he was hiding from alien monsters behind his friend, and that there were two possible outcomes. One: they die, and the aliens kill Helia first to get to him. Two: they live, and he has to relive his cowardice when they discuss the event later. Both situations were just the pits, so Bruce, with a renewal of his wordless scream, threw one last rock at one of the aliens, and bolted to the side, scooping up a particularly large stone on his way. 

As he ran, he saw that the creature was following him, as he had hoped/feared, and with a mighty(sort of) yell, he charged it, and brought the stone down on it. He aimed for the head, but it managed to dodge around and take the blow on the shoulder. It was then that the chime sounded, and the creature, completely ignoring its wound and assailant, turned and left. 

Bruce very nearly threw the last rock at the being who later identified itself as Zordon, but by then he was confused enough to wait for it(him, he thought) to finish speaking. 

When it had gone, Bruce finally dropped the rock. 

[color=0072bc]"'M alive,"[/color] he mumbled in response to Sa'Cha.  [color=0072bc]"Dunno when Heath got here, but I reckon he's got a point. And in any case it ain't like we're leaving the cave any direction but this one, right?"[/color]
