"Yeah, well you do what you have to do, just leave me out of it. Your little power struggle with Ron isn't any of my concern. And if and when you do take power don't think you're going to be ordering me around either."

Elliot's expression changes to that of someone very perturbed by your response.

"I'm very disappointed to hear you say that, I really thought you could have a place in the new community I was planning."
"Think again, now get outta here…"

You begin to shove Elliot out of your doorway, but Leon reaches over his shoulder and shoves you back with great strength. You fall backwards on to your floor, Elliot and his gang start to enter. He pulls out a scalpel, something he probably got from the medical supplies. You happen to be right next to your mattress, so you reach in and grab your pistol to point it directly at Elliot. Now they all look like they just seen a ghost and all the bravery has drained out of them except Leon, who looks like this isn't the first time he's had a gun pointed at him, but he's still stepping back.

"You wanna fuckin' take another step motherfucker? Go ahead, I fuckin' dare you!"
"Holy shit, he's got a fuckin' gun Elliot!" a women in his group says.
"I can see that Brenda! Okay, look maybe we got off on the wrong foot here. I mean obviously you're a more resourceful man than I thought…I mean as far as I know you're the only one in this place with a goddamn gun. How'd you manage that?"
"Never you mind, just get the fuck outta here!"
"Very well, but remember, you don't have any friends in this place, and you can't watch your back all the time…"

Elliot has just announced his intentions of eliminating you whenever it's possible. You'll have to live in constant paranoia now. Unless…

You let him go

If you shoot him, everyone's going to think you're a murderer, so you let him go. Besides if he planning on taking over by force like he seems to be wanting to do, he'll show his true colors soon enough. You just have to watch your back until that time. In fact it occurs to you that you should just go tell Ron and Nina about this incident, sure they might not believe you, but it's better than saying nothing.

The next day when you wake up, you hear a lot of commotion going outside your door.

"See?! I told you! He's the one who did it! He dropped the bloody scalpel right in front of his door!" you hear someone say, sounds like Elliot.

You grab your gun and open up the door to a crowd of frightened onlookers. Elliot is in front of them speaking and then turns around when you come out.

"SO! The murderer finally shows his face! We both know what you did last night! I saw you! I saw you break into Ron's room and kill him and his friend William! Then when you saw me see you, you threatened me with a gun you snuck in telling me I better keep my mouth shut or you'd kill me too! But I couldn't stay silent! I don't care if you do kill me! I had to warn these good people that they're living with a psychopath!"

Elliot's already gone through with his plan. He had to speed it up since you were a risk to tell everyone about it, but now he's turned it to his advantage by blaming you for everything.

"WHAT?! Elliot you're full of shit! YOU came to my room last night trying to get me in your little rebel gang! You're the one trying to take over, not me!"
"LIAR! Who're you gonna believe? Me? Who's been nothing, but supportive of Ron, even when his plans weren't exactly efficient? Or HIM? Someone who's done nothing to help anyone, and has shown utter dislike for Ron and everyone else here?"
"It's true! (Sob) He has always hated Ron!" Nina cries from the crowd.

You attempt to explain, protest and argue the situation, but its no good, Elliot is a master speaker, manipulator, and everyone likes him and can barely tolerate you. Feeling yourself threatened you start pointing your gun at the crowd, but even that doesn't do any good, Elliot whips them all into a frenzy to attack you, claiming how you can't kill all of you, of course that doesn't stop you from killing some of them (Elliot being the first of course).

 
Soon you're mobbed and the gun is taken away from you where upon someone dispenses vigilante justice and caps you in the head with it.
