Juliet invites Sun along the night to submit to a medical ultrasound examination in a facility of The Others hidden in an old Dharma station to determine the date of conception of the fetus. Juliet discloses that all women that became pregnant in the island had died, driving Sun to a dilemma about who could be the father of the baby. Sun recalls when she was blackmailed by a mysterious woman about the origins of Jin and his impoverished background. Meanwhile in the jungle, Desmond, Charlie, Jin, and Hurley capture Mikhail, the mysterious Russian man (first presumed dead), and he makes an offer: he could heal the wounded woman, named Naomi who parachuted onto the island via helicopter, if they release him after the conclusion of the medical procedures. Written by Claudio Carvalho, Rio de Janeiro, Brazil

Date of Conception
20 December 2008 | by ( – See all my reviews

"D.O.C." is the exact opposite of the episode which came right before it, "Catch-22", in that while that episode was always going to be good simply due to the stories it was telling and the generally professional writing one expects from "Lost", it didn't go beyond expectations and do anything especially interesting, but "D.O.C." has little to work with but ends up being a fine episode in many respects, around as good as "Catch-22". The episode is essentially an extension of the soap-opera 'who's the father?' story with Sun's baby, the story relating to pregnancies on the island, and yet again explores some of the social attitudes in Korea and deals with Sun's father and his powerful nature yet again. Also, the woman who parachuted onto the island in "Catch-22", Naomi, is treated for her injuries. Once again proving themselves to be the perfect writers to handle the more soap-opera-like stories on the show (as opposed to Elizabeth Sarnoff or Christina M. Kim, who have written some truly puke-worthy sappy nonsense), Eddy Kitsis and Adam Horowitz deliver a script that exceeds expectations and make most of the episode very interesting.
