Where is Jonathan, and how is he doing after he is taken from the cabin?

Jonathan is at a children's clinic with Hannah. He has been diagnosed with post-traumatic stress syndrome. Sometimes he will be sitting eating lunch normally and then he sweeps his plate and silverware on the floor and starts banging his head on the table. When that happens, the staff sticks a plaster on his head, gives him pills, and sends him off to draw. All he ever draws is black scribbles.
