This episode deals with Kate once again. Her criminal life. Why was she chased by the authorities? The first scene of her flashback is trully amazing. It's surprising and gives a good punch.
Unfortunately, just like the few previous episodes, this episode fails to deliver the level of excitement of the opening scene. The pacing is sometimes awkward, sometimes better, but even compared to Lost it's slow.
In the episode basically it shows Kate taking care of Sawyer, but then, the man who was murdered Kate takes over Sawyer's body... uhm. Sounds pretty weird, and it is, but it's good. I think.
The only thing left worth mentioning is the super ending. Michael chats with his son through the hatch computer. Creepy.
