'The Mentalist' 'The Silver Briefcase' Plot Revealed, Patrick Jane Takes On A Powerful Nemesis

The con dropped back into Patrick Jane's (Simon Baker) life at the end of "The Graybar Hotel," and actress Morena Baccarin will feature prominently in Dec. 14's Orange Blossom Ice Cream.

Abbott's (Rockmond Dunbar) FBI team will continue to partner with the CIA as they take their operation overseas, this time to Beirut. In a follow up to Sunday's terrorist-related case, Jane and Lisbon (Robin Tunney) must utilize Flynn in order to apprehend a courier for a terrorist organization. In exchange, Erica will recieve a pardon for a few of her past transgressions.

"I was really glad to come back one last time before the show went off the air," Baccarin dished to TV Line. "Erica doesn't disappoint. She's of course getting into trouble and conning people all over again, which is nice. It'll be a fun one for fans to watch."

Flynn will be interested in more than the case at hand, however. As whip smart as Jane, Flynn will rile up Lisbon as she tries to cozy up to the agent's new boyfriend.
