- When Raul mentions that the city was originally named Tucson, what is actually typed in the subtitles is "Tuscon." This typo is repeated at least three times during his conversation with the player.
- Raul also makes a big deal about the pronunciation and spelling of the city's name, possibly because he is the only person who knows what it originally was.
Two Sun is mentioned only in Fallout: New Vegas.
- The Courier: "So what did you do?"
Raul Tejada: "I left Mexico City behind. I made my way out to the Gulf Coast, eventually I found an old Petro-Chico refinery nobody had claimed. I stayed there for a little while, and I thought a lot about my life. I thought about the guns I'd lived by and what they'd gotten me. I decided my guns hadn't gotten me anything, and it was time to give it up. I took off that old vaquero outfit, and put on a Petro-Chico jumpsuit. The name tag said "Miguel," so I started using the name myself. Eventually I made it to Arizona... but that's another story, boss."
The Courier: "Why aren't you still there, then?"
Raul Tejada: "Getting there, boss. I'd been in Tuscon - the locals can call it Two-Sun all they want, but it's Tuscon, dammit - about 75 years when she showed up. Prettiest thing you ever saw, boss. Maybe it was just a trick of my senile brain, but I swear she looked just like my Rafaela. Her name was Claudia. She ended up taking work at one of the brothels in town. I never went to her, of course - how could I? But I looked after her in my own way."
