Kyle XY - Season 3 - Episode 9: Guess Who's Coming to Dinner
Original Air Date—9 March 2009: For once encouraged by dad, Josh organizes a great evening for Andy, centered around her favorite Star Trek theme, still unsuspecting it's already their last together, which gets an intimate home finish. To gain Cassidy's confidence, Kyle helps Nate with a tricky challenge, brilliantly. Invited to Nate's room, Amanda discovers he has a confidential file on Sara. The Tragers find Jessi is obsessed with Sara's disappearance and the theory that Cassidy murdered her. Jessi promised to stay away but manages to intrude with excessive rudeness. Afterward, he's tricked to a meeting where Kyle has to stop her torturing him to death about Sara. But that has a sting too, involving their guardian angle Tom Foss.
