So I'm still really not 100% sure, but I was reading a theory earlier that mentioned an interesting point...which may or may not be obvious by now.
In Heller's interview concerning the list, I believe the interviewer said that Patrick Jane "made a list" "that he had narrowed down to seven suspects." In which case "the list" that Bruno is referring to as legitimate is the original list Patrick Jane made. On this list, the psychic guy Shawn is mentioned. If you look at the wiki page (I probably shouldn't have...I hate spoilers), it seems that the photos on the right hand side of the page showing scenes from The Mentalist that contain that particular character are some pretty vital looking scenes from the upcoming episode. I could be completely off. I hope I am. However, the two of them (he and Patrick Jane) ARE quite a bit alike in many ways--or were anyway. So much of the other clues don't add up though--he's not young at all. He doesn't seem powerful at all, but then, when someone can get to you psychologically, they can become someone you are very devoted to. And you can con folks out of a lot of money. I don't know...just thinking. And I didn't really do any research on it, so I could be way off...
