The guy claims in the comments that this can be done during Aba Dabba Honeymoon when you need to talk to Motor Runner.

If this is true, I had no idea. But yeah, those definitely are vanilla voice actors...

I thought all of the fiends outside the vault were out there for a reason?

Reason being that they're all bat[censored] insane...

Anyone gonna try and see if that vid is true? I would but my 360 is broken.

I would but I'm limited on time atm and my only file I'm actively playing has crap rep with the Khans.

My guess is either this is legit or this is something that inadvertedly got lost to a patch they did, yknow like how Primm used to get covered with NCR propaganda if you chose them as sheriff but patches removed that to increase console performance.

I have one character who has yet to complete 3 Card Bounty or Aba Dabba Honeymoon. I'll load him up and give this a try.

Just for clarity, uploader was claiming it's during the stage you go to talk to Motor-Runner. He doesn't say if you need the Khan outfit or not. Probably wise not to touch 3-card bounty.

I entered the vault wearing the great khan outfit and the fiends inside became friendly as usual. Then I fast traveled to the rock crushing plant and payed Nephi a visit. He and his fiends were still hostile. As was Motor Runner. I'll try it again without the armor just using the speech check.

I tried it with the speech check. No dice. Unless the three fiends I had to kill to enter the vault made a difference, it doesn't work. You're probably right. This was probably lost with one of the patches.

Sadface. :C

Though that guy inexpicibly captured the ONLY evidence of those convos I've ever seen so that we actually know about them.

My guess is that if there's a console command to make people friendly, you could use it on Nephi and Co and still access those conversations.

Also? Violet's goodbye phrase cracks me up for some reason.

It wasn't lost in a patch, it's cut content that was cut either due to time or game design changes at the time. This is probably a restoration mod that restores the cut content.

Edit: Actually, this isn't new. It's been known for a while that Cook-Cook, Driver Nephi and Violet have unused dialogue trees.

http://new.spring.me/#!/JESawyer/q/455236873976046877 is what you're referring to, which MAY be the case, but it's unclear. There he's referring specifically to "unused dialog in the GECK" which might be even more convo topics that were never actually voiced, not neccesarily this and the lines for Cook-Cook and Violet. I say this because Sawyer specifically addresses Nephi discussing being Mormon, which simply doesn't exist within those vids. Could be the Mormon dialog was cut and then again the basic dialog was left out.

Looking into it now though and trying to figure out what the story is.

EDIT: http://fallout.gamepedia.com/Driver_Nephi%27s_dialogue There's even more cut dialog that I'm guessing never got audio files. I don't think it's present in cut content mods either.
