CASTLE - "The Final Frontier" - When a body is found at a sci-fi convention, Castle and Beckett are warped into the heart of fandom -- a world of egotistic celebrities, diehard costumed fans and enough drama for two galaxies, on "Castle," MONDAY, NOVEMBER 5 (10:01-11:00 p.m., ET) on ABC. (ABC/RON TOM)
