Jin-Soo Kwon, better known as "Jin," is a fictional character on the ABC television series Lost played by Daniel Dae Kim.
Jin-Soo Kwon was born on 27 November 1974 in Namhae, South Korea, to a poor fisherman and a prostitute, the latter of which abandoned Jin and his father during his infancy.
Jin's first assignment was to "convince" a government official to overlook the violating environmental regulations caused by one of Paik's factories.
While the two remain isolated from the others, Jin prepares sea urchin and offers it to the survivors, the only one to turn him down being Hurley (Jorge Garcia).
[9] One morning, Jin assaults Michael (Harold Perrineau, Jr.) and attempts to kill him in front of his son, Walt (Malcolm David Kelley).
Regardless, Michael blames Jin for the arson attack, and he and Sawyer (Josh Holloway) take their anger out on him by beating him in front of the whole camp.
Jin stops building the raft only when he hears the distress calls from Kate (Evangeline Lilly) and Claire (Emilie de Ravin) in the jungle, where he must help in delivering the baby.
[14] Upon being released, and their situation mutual, the tail-section survivors lead Jin, Michael and Sawyer back to the Arrow station.
[15] Before heading off to migrate with the fuselage camp, Jin offers his expertise by catching fish with Ana Lucia (Michelle Rodriguez) and Bernard (Sam Anderson).
Jin, knowing about Sayid's plan, demands to be given a gun whilst telling Sun that he understands more English than she thinks.
When Sawyer arrives, he teaches Jin three phrases that he describes as "what women want to hear" (which are, incidentally, "I'm sorry", "You were right" and "Those pants don't make you look fat.")
Hurley and Charlie (Dominic Monaghan) get the van running, and the four enjoy a joyriding session before returning to the beach, filled with hope.
[22] Jin finds himself involved in the investigation over the apparent deaths of survivors Nikki and Paulo (Kiele Sanchez and Rodrigo Santoro).
[23] Upon Jack, Kate and Sayid returning to the beach with Juliet (Elizabeth Mitchell) in tow, Jin shares the same disliking to her as the rest of the camp.
[29] Shortly after confirmation that Jack has made contact with the freighter, Jin watches and listens as Desmond delivers Charlie's warning, and ventures into the jungle to meet up with the rest of the camp.
After reuniting with Sun, Jin decides to return to the beach with Jack rather than join Locke (Terry O'Quinn) at the barracks.
Suddenly, Jin is torn away through time in front of Danielle and reappears later, she kills the last of her group's survivors because she believes that they had become sick and "changed".
Another time jump allows him to meet up with Sawyer, Locke, Juliet, Faraday (Jeremy Davies), Miles (Ken Leung) and Charlotte (Rebecca Mader).
Soon after Locke is separated from the group Jin, Sawyer, Juliet and Miles get sent to an ancient time, in which a gigantic statue is seen standing far away from them.
He steps out of his vehicle to acknowledge little Ben (Young: Sterling Beaumon; Old: Michael Emerson), who is a reluctant member of DHARMA, and fugitive Sayid.
Jin, Hurley, and Miles aid Jack and Sayid in taking them to the Swan Station construction site via DHARMA van, where they plan to detonate the electromagnetic pocket and prevent Oceanic 815 from ever crashing twenty-seven years from now.
Jin is tending to a critically injured Sayid, who was shot by Ben's father (Jon Gries), when Juliet manages to detonate the hydrogen bomb, leaving all of their fate unknown.
He joins Hurley, Jack, Miles, Kate, Sawyer and Sayid in the Temple, the Others' home, to stay protected from the Man in Black/Smoke Monster, but he wants to leave in order to find his wife who he has been told is also on the Island.
Late one night, while the Man in Black is off retrieving Sun (as she may be a candidate as well), Jin and the others are attacked by Charles Widmore's team.
Jin wakes up inside a DHARMA Initiative complex and meets Zoe (Sheila Kelley), who eagerly asks him about his hand-drawn map of the electromagnetism pockets, which he drew back in 1977.
At Los Angeles International Airport, he fails to declare the cash at customs, since he couldn't understand English and does not know how to claim it.
The next morning, two men named Martin Keamy (Kevin Durand) and Omar (Anthony Azizi) arrive to get the watch and the money.
He found it especially hard as it was his first time acting in Korean, and he hadn’t spoken in it regularly since being in high school, when he would talk to his parents.
Ironically, Daniel Dae Kim has the opposite problem: though he was born in South Korea but was raised in Pennsylvania, speaks English as his native language, and had to receive tutelage in Korean to prepare for the role.
[31] Despite Jin's inability to speak English, he can understand it better than most characters think, deducing that Sun and Sayid are lying to him in "The Glass Ballerina".
