Idiot Ball: It's minor, but Jeanne dies because she first agrees to come to the Baron's castle, and then tells the Baron to fuck off. Had she not come to the Baron's castle at all, she could have simply kept going as before, living in the forest. Had she come and then agreed to the Baron's offer, he would have presumably let her live in peace; she's holding almost all of the cards in their negotiation, seeing as she's the one with a cure to the plague. Hell, she could have even taken a fourth option and kept Jean with her when he came to see her, thus negating any way the Baron could have hassled them. Instead, she takes the dumbest possible route and gets burned at the stake.
