In a diner, Reese is wrapping up an investigation of a number named Wendell, when Finch calls to tell him of a new number: Walter Dang. Shaw is assigned to be a temp in Dang's office at Witherton Insurance. As Harold calls her, the two comment that public phone networks are perfectly safe to use provided they avoid certain words. John starts tracking Dang, while Shaw is called to the Subway by Finch, who reveals a new wrinkle - his cover identity has been called to Hong Kong to deliver a paper, so Shaw will have to run the computer this time.
