Claire learns about Desmond's prophecy. She later ties a rescue message to a bird and releases it. Locke, Sayid, Kate and Danielle approach a sonic barrier fence protecting the home of the Others during their mission to rescue Jack. Locke shoves Mikhail, an Other who they have captured as a hostage, into the fence and he dies. Locke, Sayid, and Kate climb over the fence without any problem. It is revealed in flashbacks that Claire shares her father with Jack. Claire meets her father for the first time after her mother goes into a vegetative state, as the result of a car accident with Claire.
