I don't like WR, i'm pretty sure that Lisbon is helping him. Remember this, Rigsby has a second personality. "Rigsby was the victim of child abuse. Rigsby worked as an arson specialist in San Diego before becoming a CBI agent." He fits Rosalind Harker description. He is strong enough. After Bosco dies he is the onlyone that doesn't drinks tequila and both of them (Lisbon and Rigsby) are the only one that drinks scotch. Wayne's fathers first appeared in "Like a Redheaded Stepchild" reference to WR being RJ. According to a character list from the Pilot script, Rigsby was originally named "Wayne Gilzean" (Gilzean: Servant of St John) so he can also be a servant of RJ.
