With big changes afoot in the White Collar division, Neal anxiously prepares to destroy the evidence against Curtis Hagan and sizes up his new handler, a young up-and-comer from Chicago named David Seigel. Seigel has a pretty good idea of how to deal with Neal, but when a sting on an online black market website leads them to a shady import/export business run by Mozzie, Neal does some deft handling of his own to keep Seigel in the dark and Mozzie in the clear. However, when the very capable Seigel's unknowingly digs up Mozzie's true identity, Neal realizes they may have to destroy Mozzie's past in order to secure his future.
At the same time, Diana's baby anxiety leaves her obsessing over work, but a hunch about the black market case soon leads to a big surprise for both her and Mozzie.
Meanwhile, the new arrangement in the office has Neal and Peter wondering where their relationship stands. But despite their mutual assurances, Peter get over that old sinking feeling that Neal is up to something, and that it may have to do with the Curtis Hagan.
