Yunjin Kim as <EM>Lost</EM>'s Sun Yunjin Kim asĀ Lost's Sun
Our favorite castaways thus far have been on the island a few months, but for Lost fans, it's been more than 260 days since Jack's super-freaky flash-forward. As the Jan. 31 season premiere (finally) draws closer, TVGuide.com is offering daily profiles — "refreshers," if you will — of the key players in ABC's island-based odyssey.

Sun, by the "Numbers": The privileged daughter of a successful and wealthy businessman, Sun (played by Yunjin Kim) is a smart, restless housewife with a degree in art history. Sun's modern ideas and independent thinking conflict with her traditional Seoul, Korea, upbringing. Her soft facial features and big brown eyes add complexity and underscore her willful determination — a perfect cover for telling lies and keeping secrets. Sun's willful determination and cunningness was most likely developed while maneuvering around her fearful and manipulative father. She maintains a garden on the island that shows her willingness to help the group and reflects her nurturing quality. Heading to Los Angeles, Sun planned to ditch her husband Jin at the Oceanic airport terminal in Sydney but had a change of heart and boarded that doomed flight with him.

Things Got Interesting When...: It was discovered that Sun understood and spoke English. Not only was this kept from the survivors but also from her husband. Sun has also not revealed to him that she has met his blackmailing prostitute mother and fisherman father, who Jin said were dead.... Sun joins Jin and Sayid in Desmond's boat to find the Others' campsite. Left alone in the dark of night, Sun is on edge and startled when Colleen embarks. Holding her at gunpoint, Sun fatally shoots her, intensifying the hostility between the Others and the castaways.

'Tis Better to Have Loved and Gotten Lost?: Bored with a husband working overtime, Sun learned her second language while having an affair with Jae Lee, the man her parents wanted her to marry. When her father, Mr. Paik, walks in and catches Sun in Jae's bed, he feels disgraced and enlists an unknowing Jin to "send a message" to Jae. Jin beats the crap out of Jae but doesn't have the heart to kill him. Leaving the hotel, Jin is shocked when Jae falls out of the window, lands on his car and dies in an apparent suicide.

Six Degrees of Serialization: Sun, Kate and Juliet's sister Rachel have all used a Widmore pregnancy test. (Widmore is the last name of Desmond's love interest, Penelope.)

Sun's Season 3 Story: After convincing Sawyer to give up one of the home pregnancy tests he's been hoarding, Sun learns she is pregnant. This is surprising because Sun knows Jin is sterile and it's problematic because he believes it is she who is unable to conceive. Sun confronts Juliet about her "research" and in the middle of the night Juliet takes Sun to the Staff Station for an ultrasound. Juliet confirms that Jin is the father and the baby was conceived on the island, stating the average male sperm count is around 60 million but on the island it's five times that.

How Sun Has Us Puzzled: Though she has lied about many things, Sun is truly happy with the news that the baby she is carrying is Jin's. The bad news is that none of the women who got pregnant on the island lived through their third trimester. Can Sun beat the odds of the impending tragedy? If she is rescued soon, can she still have the baby?

Our Wild Prediction: Sun will go into premature labor but die giving birth to twins. The children will not be motherless as they'll have visions (like Walt and Jack's father Christian Shephard) of Sun teaching them to tend a garden, speak English and Korean, and lie in order to get their way.
