The April 21 “Finder” episode of Bones serves as a backdoor pilot for a potential Fox fall series centered on Walter Sherman (Geoff Stults), a former military policeman who believes brain damage that he suffered in Iraq hasn’t just made him freakishly paranoid, but also gave him a preternatural ability to locate anything — or anyone. Booth (David Boreanaz) and Brennan (Emily Deschanel) travel to Florida to solve the murder of a maritime museum security guard, and once there, Booth suggests they call on Walter to help find a stolen treasure map. As you can tell from our first look at Walter in action, he and Booth have a history. The scene also introduces Walter’s associates: Leo Knox (Michael Clarke Duncan), who serves as his legal advisor, bodyguard, and best friend; and Ike Latulippe (Saffron Burrows), the badass who drives the boats, flies the planes, and owns The Ends of the Earth, the bar they call their headquarters.
