Season 6

Complete listed story — includes the ending

1. Borrowed Time

Peter brings Rebecca in to help locate Neal, who is being held captive by one of her former associates, Jim Boothe. Meanwhile, Jim wastes no time letting Neal know that if he doesn't comply with his demands he'll be pushed down an elevator shaft. Jim has lofty aspirations of joining an exclusive group of thieves, The Pink Panthers, and his entry ticket is the diamond currently held by the FBI. He needs Neal to steal it back. But Neal has a better plan - he thinks the situation calls for a grander gesture, and, for his trouble, he expects something in return. Elizabeth tells Peter that she is pregnant. Rebecca, upon leaving white collar, takes an agent's gun which leaves the second agent no choice but to shoot her, killing her in the end. As Neal says, "She made a choice. For Her, it was better to risk almost certain death than go back to jail."

2. Return to Sender

The U.S. Attorney General signs off on a contract, written by Mozzie, guaranteeing Neal's freedom if he helps take down the Panthers. Neal goes to his first meeting with them, without his anklet, and is surprised to meet Keller, who according to Russian authorities is still in one of their prisons. The Panthers assign Neal to steal a stamp about to be auctioned by an Argentine woman. Neal and Peter obtain admission to the auction by posing as a reclusive father and son, and Neal successfully takes the stamp in spite of a sophisticated security system. But the FBI will not release the stamp, so Neal makes a forgery which Keller vouches for. Neal deduces that Keller is an undercover Interpol informant, and confirms this with him, agreeing that neither can afford to expose the other. The Panthers tell Neal that the purpose of his theft of the stamp was to test the security system in preparation for a bigger job. Mozzie deduces that Elizabeth is pregnant, and Peter later tells Neal.

3. Uncontrolled Variables

The Panthers assign Keller and Neal to copy a data disk from a safe in a security firm's office. Neal cultivates Amy, the assistant to the firm's head, and gets Mozzie into the safe, but the disk uses 1970's technology and Mozzie must take it home to read it. Before they can get it back to the safe, Amy's boss returns early from a trip and discovers it missing. Neal suggests that Amy confess to taking it to expose the security weakness, then ask for a promotion. Instead she quits her job in disgust and Neal is broken-hearted at having betrayed her. Keller and his Interpol handler Luc give the disk to the Panthers, and the FBI are able to interpret it as instructions to route some high-value cargo randomly through US airports.

4. All's Fair

Five years ago, while Neal was in prison, Mozzie met, worked with, and married a con artist named Eva before she swindled and abandoned him. Now Eva is back, asking for a divorce so she can marry Jack, a wealthy man who has recently devoted his life to charity. Neal and Peter determine that Eva and Jack are working together and plan to steal a Faberge egg, leaving Mozzie as the fall guy. They stop the theft, but Mozzie allows Eva to escape, without signing the divorce papers. Meanwhile, the FBI figure out that the Panthers' target is a plane bringing hundreds of millions in cash back from Europe, to a random airport determined by the stolen algorithm. Peter has the San Francisco FBI stake out the latest plane, but the Panthers don't show because, as Woodford tells Neal at June's house, they know that they have a mole.

5. Whack-a-Mole

Woodford does not know who the mole is, but he is sure it is not Neal since a spy bug was found before Neal joined the group. Neal refuses to help find the mole, making Woodford trust him even more and reveal the plan to steal the cash from the airport via a massive armed assault. Peter finds that the spy bug was planted by Luc to spy on Keller, and he asks Luc to pull Keller off of the operation. Peter, Mozzie and Neal brainstorm ways the Panthers could steal the cash less dangerously, until Peter hits on the idea of using pneumatic tubes built decades ago to move mail out of the airport. Luc finds out Neal is hiding something and decides to disobey Peter and leave Keller on the operation. Keller kills Luc and puts his own tracking chip on Woodford's deputy, who is then killed by Woodford. The FBI and Interpol agree to keep the operation going so Luc's death won't be in vain. Peter misses the appointment with Elizabeth to view the first sonogram of their son, and vows to her that he will never let anything else be a priority. Mozzie begs Neal to be introduced to the Pink Panthers, but Neal refuses, telling him it's not the right time. Since the Panthers are now one man short, Neal brings Peter to the meeting stating he's the one who's been helping him. Woodford responds by aiming his gun at Peter.

6. Au Revoir

The Panthers' plan proceeds as planned except for two things: Mozzie intercepts a portion of the cash by opening the pneumatic tube in a tunnel, and the FBI arrests everyone at the end. Neal and Keller sneak away from Peter and meet Mozzie in the tunnel, where Keller betrays their arrangement and apparently shoots Neal in a struggle. Peter arrives, kills the fleeing Keller, and finds Neal being taken away in an ambulance. At the hospital, he and Mozzie view what appears to be Neal's lifeless body. One year later, Peter and Elizabeth are raising their infant son Neal when a mysterious delivery of a bottle of fine wine inspires Peter to investigate a storage unit containing evidence that the original Neal faked his death. Peter smiles and laughs as he concludes this, and Neal Caffrey is last seen in Paris, perhaps in search of a new adventure.
