R.N.A.

“Ah! Of course. A pleasure, Mx. R.N.A.”
Now Mahavir felt silly for not assuming—R.N.A. was written straight across their body(?), after all.

“Er, my full name is Mahavir Ignatius Attenborough, but I don’t go by my initials likewise. U-unless you’d prefer to call me that, in which case I don’t mind?” Oh gosh he had to be doing something wrong here with all the talking things. He coughed quietly into his elbow.
R.N.A. This place is full… of flammable objects, yet you… are on fire.

“Ah, no—there’s no cause for concern. It’s only my hair.” He patted his hair tie, apparently as proof. “As it is, I… don’t believe I could catch anything on fire if I tried, let alone by accident. I’ve worked here for a little while now without incident, at least.”
R.N.A. How do you know… how to get out of the car? You said you understand… little of the train. Why can we not both read and write… a letter?

“Um…” He’d hoped admitting he didn’t know much would prevent questions he didn’t know how to answer, but… He could at least cover part of it?
“People have certainly tried to do both. But as soon as you put your letter out to be sent, nothing can open your letter—hands or blades or water or, um… one fellow tried some kind of acid, I believe? It didn’t work either way.”

“And if you open your letter, you simply… cannot stamp an envelope here? The car seems to tolerate writing, but no stamps will stick, and I have no way to deliver a letter without a stamp. Perhaps if someone already had a stamped letter in their possession upon entering the car…? But that hasn’t happened, so I couldn’t say for sure.”

“I apologize if that upsets you.”
