The smoke monster kills Seamus, Jack lets the group out of Hydra cage

As Sawyer and Kate are inside the cages, Sawyer says that it feels like they're going in circles since they're back in there, but this time the gun was pointed at Kate's head.

Close by, Jin and Sun sit and Jin learns that his little girl Ji Yeon is with Sun's mother. He tells her that he saw pictures of her and she is beautiful. Sun then tells him that she has his wedding ring and then puts it back on his hand.

Suddenly, the power goes out killing the lights and the pylons. One guy from Widmore's group says that somebody killed the power and Seamus tells him to get a team to the generator. Then, the signature sounds of the smoke monster can be heard. Hurley says that now they're all going to die.

The smoke monster emerges from the jungle, and as it tends to be the case, Widmore's team attempts to shoot at it. It grabs Seamus and slams him against the cage which kills him. The monster quickly retreats back into the jungle, but can still be heard, presumably taking care of the other guys that were with Seamus.

Kate sees the keys on Seamus' belt and tries to grab them, but her arms are not quite long enough. Frank attempts to kick the cage door open with no luck.

As Kate is still reaching for the keys, suddenly a hand grabs them. We see Jack has come to let them out of the cage. Jack says I'm with him, nodding in the direction of the monster. Everyone then runs away.

Sawyer & his group are locked in the Hydra cages

At the Hydra Station, Widmore's team are setting up the portable sonic fence pylons next to the cages as Seamus and the others march Sawyer's group to them. When Seamus order Sawyer into the cage, he refuses to go back in there. Sawyer takes Seamus' gun and turns the tables, but Charles Widmore shows up and fires a gun into the air, then points it at Kate (a familiar scenario resembling season 3).

Widmore informs Sawyer of something he already knows. Widmore says that he has a list of names including Ford, the Knows and Reyes, but not Austen. Sawyer gives the gun back to Seamus, who gives him a knock in the gut with said gun (flashes of Pickett).

As the group gets in the cage, Widmore tells him that they're putting him there for their own good. Widmore asks one of his men if the sonic fence is live yet and the guy says it will be another hour. Widmore says that they don't have an hour because "he's coming," he being Locke.

So how exactly does Widmore seem to have Jacob's list? While he seems very afraid of Locke, it's still unclear exactly what his motives are.

Sawyer revisits the Hydra station, finds Kate's old dress

Sawyer reaches the Hydra island in the canoe and heads to the abandoned Hydra station. He somberly revisits the polar bear cages where he and Kate spent so much time in the first part of season 3. He finds the flowered dress that Ben gave Kate to wear that prior to that belonged to Alex.
