A blast from Crater's laser pistol blasts away the supporting column of rocks directly behind Kirk. This causes both him and Spock to hit the dirt. The old ruins give way and collapse.
Crater: (shouting to cover the distance)
"WE DON'T WANT YOU HERE!
WE'RE HAPPY ALONE!
I'LL KILL TO STAY ALONE!
YOU HEAR THAT, KIRK?
OR YOU'LL HAVE TO KILL ME.
I DON'T CARE EITHER WAY."
