Plot summary
In a flashback, Michael goes after Walt but is captured by the Others and taken to their primitive camp. He is asked about Walt's strange behaviors, and after a week is allowed to briefly see him. Walt says that he is forced to take "tests" and the Others aren't who they appear to be before he is taken away, and Michael is instructed to free Henry and bring Jack, Kate, Sawyer, and Hurley to them to get Walt back. In the present, he fails to convince Hurley to fight the Others, and Sayid becomes suspicious when Michael refuses to take him along.
Charlie finds a vaccination kit in the pallet and gives it to Claire. Vincent leads him to the last of the statues, which he throws into the ocean. At Ana Lucia and Libby's funeral, Hurley decides to go with Michael, and the survivors notice a boat in the water nearby.
