Series 1, Episode 17
Tempers are starting to fray when Michael's hard work on the raft go up in flames. He accuses Jin of the sabotage and the two fight on the beach... but has he got the right man? The back story of Jin and Sun's marriage is told which shows Jin as feeling awkward with working as a hitman for his father-in-law and is shown to be a softie at heart. Sayid and Shannon get a bit closer than usual, and Locke plays peacemaker with the camp.
My highlight of the episode is seeing Sun giving Michael a much needed slap!
