Other characters rumored to appear in "White Orchinds" include long-time favorites Wayne Rigsby (Owain Yeoman) and Grace Van Pelt (Amanda Righetti). Meanwhile, there is also a chance that the recently introduced Jimmy Lisbon (Robert Belushi) and Stan Lisbon (Derek Phillips) are also expected to make an appearance.

So, why are all these familiar faces making an appearance? Lazarus, the series' upcoming serial killer, could make the case personal by going after Lisbon's (Robin Tunney) friends and family. Or, there could be a more joyous reason for the gathering. A Jisbon wedding would make many Mentalist fans especially happy, but the cast has yet to confirm the notion.
