Don't think GVP is RJ but think she will lead us to him somehow.  Heller said "you will see the white whale" [for last season, meaning the killer will be out there] -- the "white whale" a reference to killer whale Moby Dick.  I realized that besides King Arthur references in the character names, there are Moby Dick themes, as well, in The Mentalist.  In MD, Ishmael, an outcast orphan [from Bible, too] joins Captain Ahab [who lost his leg to the "white whale killer"] on his ship out on the Pacific to find Moby Dick.  It's about an obsessive search for a killer in a sea of unknown -- and how revenge can destroy you [as Captain Ahab and his crew, but for Ishmael, go down trying to take the killer whale down].  Moby Dick is symbolic of fighting forces that are often beyond our control.  There's also a character, Elijah, in MD [and also from Bible, meaning Prophet] who tells Ishmael he mustn't have soul to go on this journey, and likens a soul to being a "FIFTH WHEEL ON A WAGON."  What's so interesting about all this is that there are many character names relating to: the SEA, WATER, CLIFF, ROCK, RIDGE, BOATS and WAGON MAKERS & REPAIRERS.  Is Van Pelt the "5th wheel" on the CBI team?  Did Ellis Mars [meaning Elijah: Prophet/War, Blood Red] predict something overlooked?  Maybe he will come back?  Interestingly, an anagram for Patrick Jane is "Captain Jerk" and the longest word found in Van Pelt's name is "parentage" -- her father is mentioned, and supposedly known by RJ associate and killer Craig O'Laughlin [whose name means Rocky Water/Lake] so I think Grace's father may become known or revealed this season, considering Van Pelt means "curer of animal hides," like Tanner [Orville & DuMAR Tanner], also RJ associates.  Van Pelt's family obviously has red hair somewhere down the line; her sister committed suicide and Jane says she's repressing a terrible memory.  She has a psychic aunt named Yolanda [which means Violet] -- there are just too many loose ends with VP, these all have to lead somewhere.  Now, I'm thinking Jane's Suspect List may have been his ploy to throw off "Roy" LOL and that it's been Van Pelt all along who is going to lead us to RJ [not that she knows it].
