Psych Season 4 Episode 12 : A Very Juliet Episode

In 2003, Juliet made a pact with her boyfriend Scott Seaver (Josh Braaten) to meet up in seven years. After he fails to show up, Shawn finds him, and by extension endangers his life since he was a key witness against mobster J.T. Waring (Arnold Vosloo), who was convicted for the murder of a U.S. Marshall. When Waring denies killing the Marshall, Shawn must prove him right in order to protect Scott.
