Charles Widmore returns to the island in a submarine

Just off the island, we see a distant point-of-view shot of the beach camp reunion. Out of the water, a periscope appears. We then see to the point-of-view of the periscope which pans across the beach camp.

Inside the submarine, a man looking through the periscope says that there are people on the beach and asks if they should stop. We see none other than Charles Widmore tell him to proceed as planned.

So what exactly is Charles Widmore doing back at the island and which side in the coming war will he join?

Ilana makes Ben dig his own grave, tells Sun she could be a candidate

Back at the beach camp, Ilana is gathering bits of wreckage to later tether Ben to a tree. While doing that, she reveals to Sun that either she or Jin or both of them are candidates to take over Jacob's job and it is Ilana's job to protect them.

We then see Ben, going through Sawyer's old stash. He picks up a copy of Booty Babes magazine and the book Justice In Truth In Action by Benjamin Disraeli. There is also the book The Chosen by Chaim Potok in the stash too (a little nod to the candidates being chosen).

Ben pulls out an Oceanic water bottle and says to Frank that he remembers the plane crash like it was yesterday. Frank then reveals to Ben that he was supposed to fly the plane and the reason he didn't was because he overslept. Ben notes that the island got Frank in the end anyway.

Ilana then points her gun at Ben and forces him to the graveyard. She tethers him to a tree with the items she'd been gathering and tells him to dig his own grave.

Sun finds Charlie's 'DS' ring in Aaron's cradle

As Sun is walking through the beach camp, she notices the cradle that Claire kept Aaron in and walked over to it. She sets in upright and notices something in the blankets. She pulls out Charlie's DS (Dexter Straton/Drive Shaft) ring that Charlie left in the cradle before he sacrificed himself at the Looking Glass station. It's taken two seasons for someone to find that ring. Does it signify something to come in season 6?

Ben admits to Locke that he pretended to talk to Jacob at the cabin

Fake Locke leads the others to the old flight 815 survivors camp. Locke tells everyone that they should get to where they're going by nightfall and to take a moment rest. With a sinister smile on his face he says "Considering what I have planned for you, you're gonna need it."

Later, Ben is sitting alone on the beach when Locke comes over to ask him if everything is alright. Ben says that he was enjoying some along time. Locke points out the Swan hatch door that is sitting behind them. Ben says "It's a door. How about that?" Locke points out that it's the door to the hatch where they first met. Locke asks "Do you mind if I ask you a question?" and Ben sarcastically says "I'm a Pisces."

Locke asks Ben what happened at the cabin when he first took him to meet Jacob. Ben admits that he was talking to an empty chair and was as surprised as Locke when things started flying around the room. Locke asks him why he would go to the trouble of making all of it up. Ben says that he was embarrassed and didn't want Locke to know that he had never seen Jacob. He says "So yes, I lied. That's what I do." Locke accepts his answer and starts to walk away.

Ben stops him by asking "Why do you want me to kill Jacob, John?" Locke uses some of Ben's manipulative tricks on him. Locke says "Because, despite your loyal service to this Island, you got cancer. You had to watch your own daughter gunned down right in front of you. And your reward for those sacrifices? You were banished. And you did all this in the name of a man you'd never even met. So the question is, Ben, why the hell wouldn't you want to kill Jacob?"

Looking back on this scene, this was another tip that Locke was not Locke. Locke has never been a manipulative guy for the most part and he is definitely quite Ben-like during this scene.

It seems now that that cabin scene in season 3 has a totally different meaning than we though it did. If Jacob was not in the cabin, who made things fly around the room and made the man appear in the chair? It would seem that the same entity that is now inhabiting Locke is a likely candidate.

Also, what plans for the others does fake Locke have? Does it involve killing the Ajira passengers or is it something more?

The group finds Ajira Airways water bottle in outrigger canoe

The group returns to the beach to find the camp back but broken down and littered with debris. Sawyer was hoping for a Dharma beer, but only finds empty cans. Locke finds Vincent's leash but Vincent is no where to be seen. It's then that Daniel notices that the zodiac raft is gone, but Miles notices two outrigger canoes on the beach. Daniel says that they look pretty old, but Miles points out a water bottle with the Ajira Airways logo on it. Juliet says that it's an airline based in India that flies all over the world. Locke points out that they should not stick around to find out when the people who were there would come back and that they should take one of the canoes.

It would seem that the survivors are in the future now. Who came in the two canoes? What Ajira Airways and what is their relation to the island?

Beach camp is attacked with flaming Arrows, Frogurt bites the big one

Miles comes walking of the jungle with a boar over his shoulder that died in the jungle. Everyone turns in confusion when he says "Don't worry it's fine, it's only been dead three hours." Miles' ability to hear the dead is still an incredibly intriguing mystery on the show.

Moving on, below you'll see the camp being attacked with flaming arrows. The obnoxious Neil Frogurt is the first one to get hit and die. Are the people firing the arrows the same people that will attempt to capture Sawyer and Juliet later? Flaming arrows would seem to be a tactic of the natives.

The beach camp disappears

After the island moves back in time the beach camp disappears because it hasn't been built yet. Here we see the remaining survivors, freighter folk and Juliet checking things out.
