Shawn and Gus are being followed by the worst P.I. ever. Shawn's actually taken pictures of himself being surveilled over the last few days. Finally they confront their stalker, who lights a cigarette and confesses that he was hired by Gus' wife. Gus admits to a shocked Shawn that he met Mira Gaffney when he was in Mexico on Spring Break in 1997. She was crazy and could get him to do things no one else could, like skydiving and getting married on a drunken binge.
