I love AUs where someone from our modern world is just dropped into a fantasy land, but one aspect I don’t think is explored enough is how would someone from a completely different world speak English? Like imagine you were dropped into Ravka, you wouldn’t know Ravkan and no one there would know English, so you wander into some army camp and start speaking gibberish, they would probably assume you were drunk, honestly you could probably fake being Grisha for a bit if you paid attention in science class, Ik they have guns and light but you could probably mix baking soda and vinegar and a peasant would have an aneurysm
Human Cas trying different drinks for the first time (Victorian child inspired):
Water
*frowns* "It tastes like time..."
Dean: So you don't like it? Cause you kinda need that to-
Cas: No. It's great. (and he means it)
Milk
Cas: "You know, adult humans really shouldn't be drinking this. This would have been unheard of in the 18th century, and I really don't understand the appeal of cow secretions-"
Dean: *plugs his ears* Ahhh... enough. I do not consent to hearing those words.
Sam: You know, he's not wrong! Get this-
Dean: Kindly, shut! up!
[Dean slides the glass forward]
Try the milk. : )
Cas: *sighs and tales a sip* I am not a calf. This is weird. I feel gross, Dean.
Dean: Stop being so dramatic! This is why you're trying everything now, so you don't embarrass us in public. Come on, it ain't that bad.
[Cas then spends half an hour on the toilet. He is apparently lactose intolerant.]
Diet Coke
Cas: [Wearily] Is this dairy free?
Dean: It's diet-friggen-coke, Cas. It's dairy free. It's also sugar free! Because someone [he glares at Sam] has a bad taste in pop. Real honest sugar is probably better for you than this junk.
Cas: Agreed. The fact that it's sugar free does by no means make cocaine good for you. It's actually quite concerning that you boys drink this. I think we should do an "intervention."
Dean:
Sam:
Cas: Does 6pm tomorrow work for you two? I'll find some folding chairs and arrange them in a circle.
[They never could get Cas to drink diet Coke, because why is it still called Coke, if there's not cocaine in it? and that's false advertising, which I also do not condone.]
...........................................................
If people enjoy this one, I'll take suggestions for other foods for Cas to try
