I'm gonna put on my detective hat and guess how the Prince might get pissed.
We already know the Prince thinks blondie is sus from the way he asked her what book she read to figure out the last problem.
We also know that there's a law that was overlooked by Marie that states gold or valuables cant be traded between countries of differing religions which the Prince had to explain.
This time though, I feel like the upcomming scenerio might play out like this:
- Marie tells blonde that the empire can trade food for showing them how to plant sugar
- blonde just takes the idea and runs with it to the prince "oh hey, i came up with this plan (insert maria idea here)"
- Prince, being sus of blonde, goes like "oh wow, wonderful, wait, then can't we just trade money or valuables for food?"
- blonde: "oh yes, good idea my prince"
- prince: "it's cuz laws forbid us from doing so, why was your first idea trading food for sugar growing instead of money if you didnt know that law? spill it bitch."
