Plot summary
Michael tries to sue Susan Lloyd for custody of Walt, but eventually relents and gives him a stuffed polar bear as a parting gift. In the present, Desmond locks Kate in the pantry. An alarm goes off and Desmond forces Locke to enter the numbers and push the computer's button, causing the 108 minute timer to reset. Jack enters moments later as Kate, having crawled into the air ducts, watches. With Jin missing, Michael and Sawyer argue about the raft's destruction as sharks circle them. Sawyer swims for the raft's pontoon as Michael fends the sharks off. They reconcile as Michael admits that he should not have brought Walt with him and soon wash ashore on the island, where Jin is being chased.
