Origin: Bernard and Jin met while the tailies imprisoned Jin, Michael and Sawyer.
Since Then: Jin and Bernard were the survivors' only two married men. When the two plane sections merged, each of them reunited with their wives. Jin advised Bernard against fishing for oysters, and he was the last to abandon Bernard's S.O.S. sign. The two and Sayid later helped defend the camp from Others, and Bernard broke under interrogation when they threatened Jin. Bernard advised Jin after Jin learned of Sun's affair. When they traveled back to the 1970s, Jin spent years mapping the island, searching it for Bernard and Rose.
Origin: Rose and Bernard meet when Rose's car gets stuck in the snow and Bernard offers to help push it out. Afterwards, Rose asks Bernard out for coffee
Since Then: Rose and Bernard meet when Rose's car gets stuck in the snow and Bernard offers to help push it out. Afterwards, Rose asks Bernard out for coffee. The two begin dating and on one date while visiting the Niagara Falls, Bernard proposes to her. Rose hesitates to say yes, telling Bernard that she is dying of cancer. Bernard decides that he is not afraid of her illness and tells her still wants to marry her. On their honeymoon trip he takes her to Australia to see Isaac of Uluru, a faith healer, hoping that he will cure her cancer. Rose gets upset with Bernard, but goes in to see Isaac. Even after Isaac tells her that he cannot cure her, Rose pretends to Bernard that the healer has succeeded just so that Bernard will be at peace with the situation in order to enjoy the rest of their time together. Bernard spends most of his first 48 days on the Island under the assumption that Rose is dead, but Rose believed that Bernard was alive. When Sawyer and Michael tell him she is alive, he is eager to find their camp. They reunite in "Collision", and Rose tells him that she believed the Island healed her cancer. During the time shifts once Ben moved the island, the two are briefly separated, but quickly reunited. Bernard and Rose are married - lovingly so - in the flash-sideways timeline. As on the original Flight 815, she carries his wedding band on her necklace when they fly. Later, they are shown in the church with their island friends to move on.
