"{Slow chuckle on the radio, uneasy undercurrent} Heh... now, come on, you open up. {Colder, angrier}Open up, damn you."
"Open the vault... {trying to make a deal} I can make it worth your while, {now angry} think about what you're throwing away. {Trying to bait player, make a deal} I have other weapons, other technology I can share with you."
"{Low, trying to greed player with lure of other treasures} And the Big Empty... I know the way there. I know some of its secrets... if..."
"{Backpedals} The collars... the collars were a mistake, I see that now. Why would I kill you? After {emph} all you've done... after all {emph} we've done together."
"{Challenging, hates being ignored} Are you listening to me?!"
"{Looking around, reverent, quiet} Everything down here... I swear... so much you could use, you could rule the wastes with what's down here..."
"...make your own army, re-shape the world, and if others disagree... put {emph}collars on them, I can show you how."
"{Anger/fear} Don't you leave me here. You can't do this to me. {Coughs, wheezing}"
"Eh? Getting dark in here. Machine... machine's losing power, no. I still have Pip-Boy light... maybe... maybe... no, no, that doesn't work."
"{Scratching on metal, clawing for door, quiet, to himself}Where... where is the door. Can't find the door."
"{Rasping breath, to himself}Calm, been in worse situations... find a way out... {vicious, last part is threat}somehow, then find that Courier..."
"{Running through options, to himself}Maybe Veronica... no... no, she thinks I'm dead."
"{Himself} Must be someone... maybe that {emph} other courier, one with the flag on his back... maybe... no... no, said he'd never come to the Sierra Madre..."
"No way out. {Beat, frustration} Can't... can't end like this."
"{Cold, firm, addressed to the player as his final words} You. I know you can hear me. When you die, Courier... I'll be waiting. Your grave's going look just like this vault."
"{Cold, quiet, hissing whisper} When you die... I'll be waiting here... at the Sierra Madre. {Faint, quiet, as if dying} Waiting."
