<P> Juliet seems to present a gentle counterpoint to Lassiter 's gruff , rigid style . She reminds her partner repeatedly to `` be sensitive '' with the media , the victims , and the witnesses of their cases . Unlike Lassiter , she is friendly with Shawn Spencer and more willing to work with him and Burton Guster . Lawson says that , although Juliet is bemused by Shawn at first , she has slowly gained respect for him and by the second season , Juliet reveals a `` very friendly , comfortable relationship '' . The actress says she thinks that , despite some skepticism , Juliet does believe that Shawn is psychic . By the end of the fifth season , Shawn and Juliet are romantically involved . By the middle of the sixth season , Shawn is ready for marriage . Her older brother Ewan , played by John Cena , is an army soldier whom she had to arrest when he attempted to murder an actual killer to protect the army . Ewan was supposed to go to prison but his high level bosses made him vanish . Juliet claims Ewan was the reason she became a cop , that him joining the military gave her enough confidence to join the police force . Her estranged con artist father Frank O'Hara is played by William Shatner . She seems to be Scots Irish , with her family hailing from Inverness . </P>
