So I just got inside the casino, and now Elijah tells me that I can kill my comrades off. But I really wouldn't like to kill them, not just yet. Can I do it later in the game?

There are options to do so.

You can convince Dog/God to be the dominant voice, or neither, and forge a completely new Dog.

I know you can talk Dean down, but I didn't.

And to be honest, the mute gave me no problems.

well, let me tell you they aren't going to be your companions any more (I hope someone makes a mod that lets me keep them though)

they are all somewhere in the Sierra Madre, and their behavior towards you will depend on how you treated them back in the Villa.

You don't have to kill them, but they are of no use from this point on. You can't recruit them anymore, and they will vanish whether you kill them or not, after you enter the vault.

So I'm all alone from this point forward? :sadvaultboy:

You still have the wise words of Elijah to guide you.

Can you kill Elijah? I really want to kill him. And I plan on killing all of the companions for their clothes and equipment because I know that they disappear after the DLC is over.

Yep. Its the easiest ending to do.

Elijah says to take care of the others, and then Christine can finally talk again and the first thing she says is to take care of Elijah. IM NOT A BABYSITTER! :cryvaultboy:

I lol'd
