Season: 1–6, Episodes: 92, Faction: Survivors
Kwon Jin-Soo (Hangul: 권진수, Hanja: 權眞秀), more commonly known as Jin, was married to Sun-Hwa Kwon and was one of the middle section survivors of Oceanic Flight 815. Knowing no English, Jin initially isolated himself and Sun from the other survivors, and when he found she’d secretly learned the language, he felt betrayed and briefly left her. He later learned English himself and involved himself more in group activities. His time on the island restored his marriage, which his violent, corrupt job had nearly ruined. He even managed to conceive a child with his wife, even though he’d been infertile. He also contributed through his combat skills, which he’d learned as his father-in-law’s enforcer, and through fishing, a humble occupation that had brought him shame back in Korea.
Jin tried a number of times to escape the island. His first attempt sent him right back to the island, into the hands of a hostile group of other survivors. He and Sun later boarded a freighter, but though Sun escaped, a disaster aboard convinced her he died. Jin returned to the Island, time traveling to 1974, where he joined the DHARMA Initiative as a security officer for three years. He returned to 2007, where he reunited with Sun. They tried to leave the island on a submarine. It sank, and the two drowned together. They stayed a couple in the afterlife and moved on with their friends.
After the Oceanic Six rescue (Mainland)
5×02 – The Lie
Three years after leaving the Island, Sun absolved Kate of blame for keeping her from saving Jin. She said that if they hadn’t left Jin behind on the freighter, they would probably all have died. (“The Lie”)
5×05 – This Place Is Death
On the dock later, Sun held a gun to Ben’s head, still blaming him for Jin’s death. Ben avoided getting shot by telling her that Jin was still alive, and he could prove it. Ben handed her Jin’s wedding ring, which he had stolen after murdering John Locke. (“This Place Is Death”)
5×04 – The Little Prince
Jin survived the explosion and his unconscious body, within the source’s radius, floated on a wreckage and traveled through time over several days. In 1988, Danielle Rousseau’s shipwrecked science expedition discovered him. (“The Little Prince”)
5×05 – This Place Is Death
Montand questioned him, but his disoriented answers frustrated the Frenchman. Rousseau eventually revealed her name, leaving a confused Jin to sort out when he was. The team dismissed his questions about a helicopter as ranting and asked him about a radio tower. Jin agreed to lead them there so he could find the beach camp.
While they traveled through the jungle though, the Monster killed Nadine and dragged Montand into a crevice under the Temple. Robert, Lacombe and Brennan followed Montand’s cries below, but Jin convinced the pregnant Danielle to stay out. The sky soon flashed and Jin was transported to the near future.
He found Brennan and Lacombe’s corpses on the beach and witnessed Danielle kill Robert in self-defense. Danielle turned her gun on Jin, thinking he too was sick, but her shot missed, and Jin time-traveled once again.
This jump reunited him with Sawyer, Locke, and the rest of their group, and he continued with them to the Orchid. After Charlotte warned him to keep Sun from the Island, Jin made Locke promise not to ask her to return. He gave Locke his wedding ring to present as proof that Jin truly died. (“This Place Is Death”)
With the DHARMA Initiative (1974-77)
5×08 – LaFleur
After one more time shift, Jin found himself in 1974. The group encountered Amy, and Jin helped carry her husband’s body back to the Barracks. The DHARMA Initiative then captured him.
Horace Goodspeed offered to return him to the mainland, but Jin joined the DHARMA Initiative. Over the next three years, he worked on the security team and helped map the island, and he learned fluent English. (“LaFleur”)
5×06 – 316
Three years later, Jin encountered Jack, Kate and Hurley at the waterfall after they’d returned via Flight 316. (“316”)
5×08 – LaFleur
Jin contacted the head of security who reunited with the three. (“LaFleur”)
5×09 – Namaste
On hearing they’d arrived on a plane, Jin told Radzinsky at the Flame station to check if one had arrived. They found no plane, but they spotted an intruder, and Jin ran to apprehend him. It was Sayid, and Jin privately informed Sawyer. But Jin pretended Sayid was a hostile, and he and Radzinsky locked him at the Flame. (“Namaste”)
5×10 – He’s Our You
Young Ben later freed Sayid, and when Jin caught them escaping, Sayid knocked him unconscious. (“He’s Our You”)
5×11 – Whatever Happened, Happened
Jin awoke and took Ben’s bleeding body to the Barracks. (“Whatever Happened, Happened”)
5×14 – The Variable
The next day, after their cover was blown, Jin, Jack, Kate, Sawyer, Juliet and Hurley met to discuss options. Sawyer suggested they leave the Island or head into the jungle, but Jin refused to leave as long as a chance of finding Sun remained. (“The Variable”)
5×15 – Follow the Leader
DHARMA members entered the Barracks with guns, but Jin, Hurley and Miles escaped the Barracks and headed for the beach. Dr. Chang, who now believed they’d come from the future, followed them and demanded answers. Hurley tried and failed to maintain their story; he denied the Korean War’s existence, to Jin’s annoyance.
The group later watched people evacuate the island by sub. (“Follow the Leader”)
5×16 – The Incident, Part 1
They then returned to the Barracks and rescued Jack and Sayid from a shootout. Jack shared his plan to reset time, which would, if successful, reunite Jin with Sun. Jin agreed to help. (“The Incident, Part 1”)
5×17 – The Incident, Part 2
They headed to the Swan site, and Jin stayed out of the ensuing gunfight with Hurley and an injured Sayid. He remained there during the Incident and the time flash that brought them to 2007. (“The Incident, Part 2”)
