This episode came together in a way I did not see coming. I loved witnessing the "battle of wits" between Jane and Panzer, especially at the "round table" ... you could just see the mental wheels turning on each of their faces. I watched the episode twice, and loved it even more the second time as I picked up on things I missed the first time through, eg. the wall behind Panzer when he is on the phone with Jane.
Bravo, Mr. Jane! You skillfully manipulated two serial killers in one clever play and got the confirmation you needed.
