What or who was taking surveillance of Kate and Sawyer? Jin decides to run off into the jungle to find Sun only to get taken down by darts and then taken away by Zoe and her crew. MIB/UnLocke/Smokey comes back and man is he pissed. He starts waking people up and recruits Sayid to go after Jin with him. But not before he basically tells Claire that after Kate has fulfilled her purpose she has his blessing and permission to do whatever she wants to make sure Kate doesn't get off the Island again. MIB/UnLocke/Smokey arrives on Widmore's beach and declares war.
Jin wakes up in Room 23 (remember back in Season 3 when Sawyer and Kate rescued Karl from Room 23 for Alex?). Zoe requests Jin's help in deciphering some Dharma maps as they have his name on them. He in turn demands to talk to Widmore. Widmore shows Jin a camera with pictures of his daughter and appeals to his fathery nature to help him keep MIB/UnLocke/Smokey from getting off the Island. And they walk off arm in arm to see The Package, who turns out is Desmond! (Hiya Brutha!) And Desmond while doped up on something sees Sayid in the water who was sent by MIB/UnLocke/Smokey to find out what was behind the locked door. That scene was pretty creepy actually.
Jack tells Sun about the Lighthouse while she angrily pulls up plants in her old garden. MIB/UnLocke/Smokey stops by for a visit. Trying to convince Sun that it would be a good idea to go with him because ZOMG JIN! Instead she freaks and runs somehow into a tree and waking up speaking only Korean. After Jack repeats some doctory jibberish to make himself feel important and useful, Richard comes back and instructs everyone to pack their bags because FIELD TRIP! They're going to destroy the plane. Sun gets upset because she wants to find Jin and leave the Island. Of course they don't know there's a submarine over there. Jack talks her into going with them and promises that she and Jin will leave the Island.
Jin and Sun aren't married. Silly us for assuming that. So how did he end up working for her father if he didn't start to win his approval so they could get married? She then seduces him - though he didn't look so unwilling - in her hotel room. And not for the first time. She proposes they run away together. Keamy comes knocking. He was the guy Jin was supposed to deliver the watch to. He wants the money customs confiscated at the airport. He brings in Patchy also known as Mikhail to translate the Korean for him. Only Sideways Patchy has both eyes. Sun offers to get th emoney from her own account. So Patchy goes with her to the bank while Jin goes to the restaurant and gets tied up in the walk-in by Keamy. Patchy and Sun walk into the restaurant to find the carnage Sayid left behind. Patchy and Jin get into a scuffle and Patchy once again loses an eye.
