"When you learned where the finale was going, were you surprised that Jane and Lisbon would be this close to catching Red John?
Robin Tunney: I was really surprised. I was also really shocked at some of the names on the list! They weren't revealed to me until we shot the scene. I assumed Bret Stiles and Michael Gaston's character would be on the list. But Xander Berkeley, who was in our second episode and Jack Plotnick — I was pretty shocked. It'll make for a really exciting sixth season."
