Three sneak peeks for "Lost" episode 5.11 are released. Little Ben is on the operation table and bleeding profusely while Juliet is trying to save him. Juliet told Sawyer that she needs a real surgeon to save the child, so Sawyer goes to Jack.
Meanwhile, Hurley was trying to figure out the time-traveling puzzle, theorizing that if little Ben dies then he never grew up to be a big Ben who made them go to there at the first place. Sawyer then barged in, and asked Jack to come with him, but Jack preferred to have the kid dies.
In the released synopsis for the episode called "Whatever Happened, Happened", after Jack refuses to help her, Kate is forced to strike out on her own in an effort to save Ben - but will the accident be responsible for turning the young Ben into the merciless killer he is later to become?
Also, in order to protect Aaron, Kate begins to unravel the lie that Sawyer has carefully conceived to protect the group. But when Sayid escapes it becomes clear to Horace that there is a traitor within Dharma and the island's latest arrivals all come under suspicion.
The episode airs April 1.
