As it was established in the first episode, Doug Mathews is a bright-eyed, big-dreaming FBI agent with visions of grandeur when it comes to his fairly procedural job.
Nevertheless, his bright idea of faking a commercial crew to gain information was extremely successful, and he had another big idea for the next step in the operation.
Specifically, when the FBI agents haven’t gotten the information they’ve wanted from tapped phone-lines, notably how they won their winning Monopoly game pieces, Mathews proposes a fake reunion in Las Vegas for all the past “winners.”
The agent often wants to invent new ways of breaking out of the mundanities of his job, and incorporate fantastical, over-the-top (and, obviously, top secret) missions that would seem more appropriate in a movie than in real life.
