He doesn't have Detect Poison prepared because he was planning to Create everything he ate on the way. Food has been ruinously expensive in Cheliax this year.

He has no specific reason to expect them to poison him, it's just kind of weird to invite a guy to dinner when you don't have a language in common and found him sitting around on the street not even begging for food. (Actually, in Cheliax it would remain weird even if you spoke the language and he was begging, but he can imagine that probably if you delete the influence of, uh, Asmodean clerics, then maybe that would not be too weird.)

He will sit down, but allow it to be obvious that he is puzzled by this situation.

The two of them start praying. (Blai still cannot understand them but their body language is not very ambiguous.)

Oh, is that what they're doing. Iomedae, if you could swap out my Spark for a Detect Poison I would appreciate that but I understand that this is not standard practice and will do without. Please let me be a tolerable ambassador for You and Your aims here in this strange land though I have not made it to a catechism course yet. I hope whatever is going on most of which is certainly more important than this is going well but I do not actually know if I can help You with it from this position. I'm going to just look at the ceiling for a while until they seem done because I wouldn't want to distract You unnecessarily.

It's not a very long prayer.

The possible-Andorani serves some of the pasta onto each of the three plates, then gestures encouragingly to Blai.

He casts Guidance because it helps with basically everything, whatever it is you do next, and whether the next thing he's going to do is "throw off poison" or "try to learn a few words of this language" it can't hurt. He takes a bite.

It's delicious and not poisoned at all!

Well, you can't always tell right away, but he bobs his head in an appreciative fashion.

Possibly-Andorani man seems happy about this!

Over the course of the meal, Blai can probably pick up that the possible-Andorani is called "Roberto" and the possible-Tien is called "Hiraga," as well as a handful of miscellaneous vocabulary words related to the meal.

He can point at himself and say "Select Blai Artigas", if they're doing introductions.

One of the men says something incomprehensible followed by "Select Blai Artigas"! It sounds friendly, at least. 

Smile???

Smile! 

Eventually dinner is over. Roberto retrieves a pillow and some bedding and arranges them on the couch in the other room. He attempts to mime to Blai that he is allowed to sleep here.

Polite head-bob. He'll take his armor off, even.

Once he's all set up, possibly-Tien man leaves the building.

Blai is not attacked by demons, or anything else, during the night.

The insides of buildings in the middle of cities are great that way.

At dawn he awakens automatically and prays for his spells.

He is not interrupted while he does this. 

That's good.

He loads up on Comprehend Languages, drops Spark for Detect Poison because apparently that's otherwise going to bug him, picks up a Share Language and a Communal Share Language, grabs Bestow Insight in case there's something he ought to remember about whatever deity these people follow. That last he casts right away once he's done with his prayers, and - nothing. Must be really obscure.

Not that long after he finishes his prayers, Roberto enters and gestures him into the dining room.

"Comprehend Languages." Maybe they'll recognize the verbal component. But he does also go into the dining room.

He doesn't seem to recognize it.

There are only two place settings this morning. The platter in the center of the table is piled high with pancakes. Roberto serves both of them pancakes, then prays. (It's a shorter prayer than he used last night.)

"Lord, grant that we, gathered at this table, may be filled with your goodness. May no one lack the necessities of life. We ask this through Christ our Lord. Amen."

Okay, their god is called Christ. Blai will improvise a grace - it's specifically the one Iomedae was supposed to have said over her one meal a month once she decided she should eat at least once a month, except he swaps out Aroden's name. It's what there was to be had in the Acts and that's all he has to go by. "Holy Iomedae, may this food nourish our souls as well as our bodies, and may we have the will and the power to fill every plate one day, amen."

Roberto is not going to try and strike up a breakfast conversation with Select Blai Artigas without prompting. (He has not yet been able to identify what Select Blai Artigas's language is, but so far that's only surprising and not shocking. Hiraga has Lauren trying to find records of him.)

When they don't say anything Blai tries tapping his ear and looking expectant at them.

(It's just Roberto so far today, not Hiraga.)

"I'm sorry, I still don't speak your language," he says in what he hopes is a cross-culturally clear apologetic tone. "I'm good with languages, but even if I knew what yours were called, I couldn't become fluent in a single night."

"Comprehend Languages," Blai repeats, though this time he is not casting the spell. (Would that even work? Probably it would just reset the duration, that's how it works with most things, but for some reason it has not previously occurred to him to wonder about Comprehend Languages.)
