That's really cool!!

They've been on ships before, but not exactly like this one.

So they recognize this thing here, right? And that one? And the other thing? How do you use that one?

She'll respond as she can. (Some things are similar to things she has seen, and some can be derived, and she'll say those, and some she can guess and sometimes be right and sometimes wrong, and some she doesn't know.)

Their knowledge is oddly patchy, but they know enough stuff to be more of a help than a hindrance in an emergency, it seems. Alright. They'll give them a rundown of what damage control will be like tomorrow morning, if they want. Maybe even a drill or two, if the captain doesn't mind. Better safe than sorry, right?

Thank you, they would appreciate that.

They're still treated like strangers on a strange ship, but are no longer watched after that. One of the engineers will even hang out in the lounge and maybe chat if they feel chatty.

She feels chatty! (She won't actually talk though, because they're new.)

She'd love to talk. She's a good listener, if the engineer has things to talk about.

Well, they realize the captain sees them as kind of incredibly sketchy characters, right? But this engineer doesn't have the patience for stuff like that. People are people. She has strong opinions on kinds of engines and will expound on them at length.

(Good to know for sure.)

That is very kind of her. They endeavor to be good passengers who no one will regret having taken on board.

Engines!! She wants to listen about engines.

Yeah, the Captain's misgivings aren't her concern. She just works on engines. If you guys are pirates, you'll still need an engineer, right? So she's safe.

Jewel can hear all about engines. The cast aluminum rotaries they have on this thing are finicky to keep running smoothly, but they're very light for their power, gives them a lot of spare lift to carry supplies and stuff. She once worked in this ship with a gloriously impractical and dangerous nitrate-and-ash fueled engine. That thing was a rush, she sweated buckets every time they turned it on!

And so on. Lots of opinions about engines.

They are not pirates and she is very safe. 

(Reasonable enough logic. She won't share that.)

Engines are cool!! She wants to know what a nitrate-and-ash engine is like!

Well, it was fun! See the thing about chamber pressures is......

Talk about engines can last for hours. At some point, Cook yells into the lounge that if the guests want dinner they'd better come get it soon.

Dinner is mostly grain and fruit, with a small serving of nuts, and a bowl of vegetable soup that has bits of mysterious meat in it. Half a dozen of the crew come eat at the same time. Two of them sit at a table in a corner and act prim and proper and discuss some kind of chart over the food. The rest are sort of rough-and-tumble, like their new engineer friend, and banter and shout. The raucous group is a bit wary of the visitors, but eventually one of them asks what it's like to shoot a slugthrower? He's only ever used crossbows and air-guns.

:D

They want dinner. They are not picky eaters. They will avoid doing anything alarming.

Are the prim and proper ones dressed differently from the others?

"Depends on the slugthrower. Now this one -" She can talk about guns to about the same parameters as their new engineer friend can talk about engines, censoring appropriately for the tech level and adding notes about fire safety.

The prim and proper ones have noticeably nicer clothes and a multicolored badge on their chests. Officers?

The rough-and-tumble crew seem to accept them a bit more as the conversation on guns progresses.

Nice when that happens.

They're still outsiders. Just not exactly strangers, anymore.

Soon it's time for sleep. There's a night shift and normally they'd fly through the night, but since the ship is tied down they get easy maintenance and cleaning duties instead. As passengers, they should probably just sleep - they'll set off in the morning.

Reasonably.
