He does not seem to have any idea what Blai means by that.

Oh dear. Eartap eartap?

"I still don't speak your language." Sigh. "I really hope Lauren and Hiraga were able to find something on you. I can keep talking but I don't really think you're going to become fluent in Italian just from hearing me talk."

"Italian?"

"Right now I'm speaking Italian, which is the main language spoken in Italy. I also know Arabic, Hebrew, Farsi, Haitian Creole, Latin, ancient Greek, and Old Aramaic. Someone in Rome who didn't know any Italian would usually be an English speaker but Hiraga tried that. Your language also doesn't seem to be Mandarin Chinese, any major European language, or any of the several most common languages worldwide, but I'm not as sure of that."

"European?"

"From Europe, the continent we're currently on. Uh—" He repeats the word "European" in several more languages.

"We're on continent Europe?" Yes of course they are what a stupid thing to say but Comprehend Languages is very limited.

"Yes. The other continents are Africa, Asia, North America, South America, Australia, and Antarctica."

"Avistan, Garund, Casmaron, Arcadia, Vudra, Tian Xia...?"

"I've heard of Arcadia, but only in a mythological context, I've never heard of it being a real place that someone could actually go to. I haven't heard of any of the other places you mentioned." He writes them down anyways.

He points at himself. "Cheliax."

"I have never heard of Cheliax."

"Avistan. Golarion." He mimes drawing.

Oh, he really should have thought of that. He can get Select Blai Artigas a piece paper and a pencil, and a current world map, and some outdated historical world maps. 

Blai can draw a kind of bad rendition of Avistan and the Inner Sea region.

"This kind of looks like the Mediterranean, but I think if you were trying to draw the Mediterranean you probably would've included Italy." He taps Italy on the world map.

Headshake. He starts pointing at areas. "Cheliax. Absalom. Osirion. Rahadoum. Lastwall. Andoran. Nidal..."

"I haven't heard of any of those places." 

The doorbell rings.

"Oh, Hiraga is here. I'll be right back."

He leaves the room, returning shortly after with the man from the previous day.

There's some muffled conversation as they return, but Blai can probably catch the end of it.

"...and Lauren hasn't been able to find any records of someone named 'Select Blai Artigas,' not in the flight data and not anywhere else. He couldn't have passed through the airport without leaving some record."

"Airport?"

"Where airplanes land. The main one here in Rome is Fiumicino." He is frankly pretty confused about how Select Blai Artigas is picking up vocabulary so fast for words with no obvious physical referent but maybe he does know a Romance language after all, similar enough that he can guess from cognates?

"Airplanes???"

"A... very large car that flies through the sky?" he tries. "I could show you a photo?"

"Photo???"
