ok I know nothing happened YET between them , but we don't know what will happen inseason five.Since they'll lead the people on the island. Even if they don't become a real couple before the oceanic six get back,they'll get close to each other . And they'll find feelings to each other inside them .
So since Kate is coming back.Something will happen between her and Sawyer"most likely".But Jack &Juliet to be honest I think that this is the farest they can get I don't think that they'll get further(the Jacketers will hate me for that).Any ways,Sawyer loves Kate, but she's in love with Jack and he knows that which made lots of probloms between Sawyer and Kate.so he's already upset about that. My point is we are not sure if Sawyer will choose Kate over Juliet like the fans think.I just have a feeling that LOST will end JATE&SULIET.I'm a SKater but I have to be honest with you guys,SKATE & JACKET.... almost impossiable,sorry.
