The Con skill. Every movie/TV operative (outside of cold blooded hit men) has a high Con skill. James Bond, Ocean’s Eleventy, Burn Notice, Leverage, etc., all do undercover work, even just to lie to a rent a cop. I have lost count of the number of SR ops blown, and dead/incarcerated characters, that came from Lone Star pulling someone over for a busted taillight, or a guard questioning a “maintenance” worker. I have seen TPK because a player panicked when a security guard asked a player about the latest draft pick for the Seahawks! All because they couldn’t make a half-assed Con check.
