You decide there's no need to kill Elliot. If the day should come where he begins to think about getting rid of you then you'll kill him. You need a personal reason to do it; you can't just do it on a whim.

You go back to your job and think nothing more of it.

Five more years pass...

You've been down here ten years and you're beginning to get a feeling of unease.

Elliot has turned this place in a cult compound. He's had children by all the remaining fertile women in the shelter and sterilized just about all the remaining men. He's completely indoctrinated everyone to think the way he does at this point, anyone who was still resisting him has been dealt with. He's got complete obedience from everyone now. You get the impression that killing Elliot wouldn't do much good at this point, since you'd just be overwhelmed soon afterwards by his followers.

He's regained his cult of personality, and you're just about the only remaining sane person left. Oddly Elliot still thinks highly of you, and has never tried to do anything to you either; he continues to let you do your job, with one exception. He's been sending his older children to the computer room for you to teach them how to use and work on the central computer.

"What's this?"
"Don't touch that! That'll be next week's lesson!"
"Can I access the game database?"
"No!"
"Ohhh I got a lady to appear on the screen and she's naked!"
"Stop that and pay attention!

You've become a glorified baby sitter, you've gone half insane and you're ready to put the damn gun to your own head at this point.

Over the years you've been wondering about the surface. You wonder if it wouldn't be better than living in place. One time when you were considering leaving you overrode the safety controls to the elevator which would allow you to bring it down. You could bring it down. All you'd have to do is gather what supplies you think you're going to need.

The only problem is thanks to the idiotic GZS shelter design; you'd need to trust Elliot's kids to send you back up from the computer room.

You stay

Once again you decide the risk is too high and you'd get caught before you could get it accomplished. You also don't think you can trust Elliot's monsters to do anything to help you.

The time to have acted against Elliot would've been long ago, this is your life now and you're stuck. And you also realize you can't go on waiting for the other shoe to drop. Elliot's finally gotten around to his plan of getting rid of you, you aren't blind. He's sending his kids for you to teach, so that one day they'll replace you. Then at best he'll allow you to live as a eunuch like most of the other guys here, or he'll just kill you and as far as you're concerned that's the ONLY choice he's going to have.

And if you kill him, you know you'd die soon after and someone else would just take his place. You ponder the idea of killing his children, since he seems to be a bit enthusiastic about continuing his bloodline, but you know he'd just have more and you don't think you could kill a child, at least not directly....then it suddenly occurs to you what you can do. Something you can do to shut down the whole show.

"Sonofabitch! Why didn't I think of that before?!" you say out loud.
"Ohhh! You said a bad word!" one of the children shouts, causing you look over at them all.

"You bet your ass I did! Hey kids do you find this boring?"
"Yeah." They all say in unison.
"Would you like to never have to do it ever again?"
"Yeah!"
"Would you all like to see a neat trick instead?"
"YEAH!"
"Okay! Brace yourselves!"

You whip out your pistol and start blasting the central computer, causing it to spark, shutter, and all other kinds of bad things before it shuts down completely taking all the shelter's power with it. All the children scream and run off while you're doing it. Screaming yelling by other shelter members in the distance soon follows, you can hear footsteps running towards your position, everyone's probably wondering what's going on. You take a mental count of how many bullets you used up.

"Let's see…oh good, I got one left."

You point the gun at your head and pull the trigger.
