I think that the poison is spread at night. That's why they said to the guard that is dangerous and to not go there at that time.
What I don't know is: the guard passed out (I don't know if he's dead) because the poison was in the air or because it entered the blood when she made that cut in his hand?
So, did they lie? Was the potion they drank water based lmao?
I'm confused. What did the duchess discover with the sleeping incense? Can someone explain pls?
