SPOILER: Jake and Kate bring the exhausted Michael back to the hatch. Henry tries to kill Ana Lucia, but she is saved by John Locke in the last moment. Ana Lucia tries to convince Sawyer to give a weapon to her for killing Henry, and she has sex with him. She recalls her troubled relationship with her mother and the end of her career in the police force and her short connection with Jake's father Dr. Christian Shephard. Hurley invites Libby for a picnic in a secret spot. When Ana Lucia is unable to shoot Henry, Michael offers himself for the assignment.
I believe that the final unexpected twist in "Two For the Run" surprised even the greatest fan of "Lost". I personally would never expect those happenings in the hatch. Although being a quite disturbed and unpleasant character, I liked Ana Lucia; I was also curious to know more about Libby, especially about the reasons of her internment in a mental institution. The return of Michael to the episodes, and his deplorable act, will certainly lead "Lost" to other directions. My vote is eight.
Title (Brazil): Not Available
