Sun expresses her worry to Kate about Jin leaving her. Following her advice, Sun poisons Jin's drinking water, but ends up poisoning Michael instead. Only Kate and Jack know about this. Moments before departing, Sun writes Jin a phrasebook, containing English words written in Korean phonetics. This leads Jin to apologise to Sun for his behaviour. Jin believes he is on the island because he is being punished. Jin tells Sun that he is leaving because he is going to rescue her. The two reconcile before Jin departs on the raft.
