Hydra station, located on a small island two miles offshore from the main Island. Jack initially refuses to cooperate but Juliet ultimately manages to break through and the two grow closer. She later seeks Jack's help in operating on Colleen Pickett (Paula Malcomson) when she is shot, though the surgery proves unsuccessful. In the operating room, Jack notices Ben's x-rays on the wall and deduces that he was kidnapped to remove his tumor. Juliet is sent to convince Jack to operate on Ben, but she surreptitiously plays a video of herself using cue cards telling Jack to kill Ben during the surgery and to make it look like an accident. Jack agrees to do the surgery but ends up slitting Ben's kidney sac to blackmail the Others into letting James "Sawyer" Ford (Josh Holloway) and Kate Austen (Evangeline Lilly) go. In an attempt to force Jack to play his role in her scheme to kill Ben, Juliet threatens to have Sawyer and Kate killed, after which Jack reveals Juliet's treachery to the Others. Ben wakes up during the surgery and concedes to Jack's demands, privately asking Juliet to help Sawyer and Kate escape in exchange for her freedom and finally letting her off the Island. She finds Sawyer and Kate held at gunpoint by Danny Pickett (Michael Bowen), whom she shoots and kills on the spot before helping the two escape from Hydra Island back to the main Island. Juliet is then imprisoned and tried as the Others prepare to sentence her to death for her crime. However, Jack vouches for her and makes a deal with Ben to spare her. Juliet is marked on her lower back as punishment, and her wound is treated by Jack with an aloe vera plant before they set sail with the Others back to the Barracks on the main Island. As part of their deal, Ben "allows" Juliet and Jack to use the Others' submarine to finally leave the Island but before they can depart, John Locke (Terry O'Quinn) is subtly manipulated by Ben into destroying the submarine with explosives. Prevented from leaving the Island once more, Juliet is asked by Ben to infiltrate the survivors' camp, gain their trust and mark the tents of their pregnant women so the Others can kidnap them. Juliet handcuffs herself to Kate in the jungle, where she pretends to have been gassed and abandoned with her.
