From what I gathered when plotting with Tay, Emerald is going to try to do the Right Thing again and is going to be taking Bad!Jaune to the hospital herself. Later when he's whole again, this is going to be used to develop a potentially more positive relationship with Emerald. Since Good!Jaune will be just as injured, he won't be able to communicate that he's injured. He'll probably just be very hurt on the ground.
