Widmore's team knocks out the camp, takes Jin + Sayid can't feel anything

Locke tells Sayid that he's leaving the camp to run and errand and he wants a Sayid to keep an eye on things. Sayid reveals that he can't feel anger, happiness, pain or anything else anymore. Locke says it's probably for the best considering what's coming. What exactly is coming?

Once Locke leaves, Jin sees his opportunity to make a break for it to try to find Sun. Sawyer tries to stop him, but during their conversation, the camp is suddenly attacked by tranquilizer darts which knocks out everyone. Widmore's team appears and looks through the people. Zoe and Seamus find Jin, who is the who they are looking for and they take him.
