The CIA finds Erika Flynn in Beirut. Being that her boyfriend is a terrorist, they offer her a deal. Help them figure out how he communicates with others in his cell and she'll receive immunity. Erika says she needs Patrick Jane to pull of the job.
Jane and Lisbon fly to Beirut where Jane interviews to be the terrorists new message courier as they almost drown him in a tub. Jane must memorize a random string of 81 numbers and verbally repeat them back to someone he meets in Atlanta.
Once they get the contact information, Cho puts together a team to try and take him down. Vega lies to Cho and says Abbott said she could tag along. When the operation goes wrong and the contact is killed, Cho finds out that Vega lied and tells her he can't work with someone he can't trust.
Back in Beirut, the terrorist is arrested. Erika tries to play Jane by telling him that he and Lisbon have no long term potential as a couple. Jane tells her that he loves Lisbon and he knows her game. Erika had planned to flee but Jane and Lisbon foil her plan.
Lisbon asks Jane about his personal relationship with Erika. He admits they kissed. Then she asks about Loralei. Jane tells her that he'll tell her everything about Loralei if she tells him everything about Walter Mashburn. They call it a draw and instead Jane surprises Lisbon with orange blossom ice cream and fireworks on the rooftop.
