Schmitter's Death (The Devil in the Dark)

[Mine tunnel]
(A nervous man has his weapon drawn) 
SAM: Who's there? 
VANDERBERG: (enters with a lot of men) It's your relief, Sam. All quiet? 
SAM: Didn't see a thing, Chief. 
SCHMITTER: Nobody ever does. Whatever the thing is, it's already killed fifty people. I never realised before how dark it is down here. 
VANDERBERG: Stay on your toes, Schmitter. Keep your phaser in your hand at all times. 
SCHMITTER: What good will that do? You saw what happened to Ed Appel when he shot at it. How about those other people before the monster got them? 
VANDERBERG: I'm sorry, Schmitter. I know how you feel, but we've got to have guards. 
SCHMITTER: Okay, Chief. I'll do what I can. 
VANDERBERG: Keep alert. If you hear anything or see anything, call in. Somebody can arrive in three minutes. 
SCHMITTER: A lot can happen in three minutes. Chief, is it true the Enterprise is on its way? 
VANDERBERG: It's coming. 
SCHMITTER: You think it could get here in the next four hours? 
VANDERBERG: You'll be all right. 
(The group leaves, and nervous Schmitter paces. Then we hear a scraping sound. He turns, looks and screams. Vanderberg and the others run back.) 
VANDERBERG: Come on. 
(It's mere moments, but they're already too late.) 
VANDERBERG: Schmitter. Like the rest of them. Burned to a crisp.
