Locke wants to take all of his people to see Jacob, Richard and Ben are not happy

Locke, Richard and Ben return to the others camp and as Locke passes Sun, he gives her a nod like he's figured things out. Richard tells Locke that he'll have a tent prepared for him and they'll get going first thing in the morning. Locke tells him that he's eager and wants to leave now. Richard tells Locke that they can do what he wants but he would like to him in private first. Locke asks if everyone is here and Richard says there's another group at the temple. Locke says that he wants to talk to everyone there right now. Ben stands to the side with his head down.
Locke's speech:

"Hello, everyone. My name is John Locke. I've been told that for some time, you all have been accepting orders from a man named Jacob and yet, oddly enough, it seems that no one has actually seen him. Now I'm sure there are very good reasons why his existence and whereabouts are secret. I just don't know what they are. And to be honest with all of you, if there's a man telling us what to do, I want to know who he is."

Sun approaches Locke and asks if Jacob can help them get Jin and the rest of their people back. Locke says "Absolutely" and smiles at Sun. Locke continues saying "Richard has agreed to show us where we need to go. So I'm gonna go and see Jacob right now. And I'd like all of you to come with me." The others nod in agreement and gather around him like a hero.

Richard says to Ben "I'm starting to think John Locke is gonna be trouble." Ben says "Why do you think I tried to kill him?"

Richard seems concerned and skeptical of Locke throughout the entire scene. Ben seems particularly put out when Locke says that no one has seen Jacob. It seems a bit odd that Richard is the only other that is questioning Locke. The rest of them are flocking to Locke like sheep.

Eloise is pregnant, Jack, Kate and Richard prepare to go to the bomb

At the others/hostiles camp in 1977, Charles Widmore and Richard Alpert are crouched next to Daniel Faraday's body. Widmore says " Why is it that this man looks... familiar to me?" He apparently doesn't clearly remember him from 1954.

Eloise comes over and says that Richard and Erik are coming with her and she says that they can untie Jack and Kate. She asks for a moment with Daniel as she covers him with a blanket and closes his eyes. Eloise says that she's taking them to the bomb. The dialogue is quiet, but Widmore touches her mid-drift and says "I'm worried about you. Not in your condition."

Jack asks Richard who the man is and Richard says that he is Charles Widmore. He continues saying "He and Eloise are... well, let's just say love can be complicated." Jack and Kate share a look after that line. Eloise comes over and says "Let's move out."

We learn here that Eloise is presumably pregnant with Daniel at the time when she killed older Daniel. That's a bit of a weird, no?

Jack tells Eloise that he thinks they can change what happened, Kate isn't happy about it

Erik the other throws Kate on the ground in Eloise's tent and then gets a punch in the face when he tells Erik to take it easy on her. Erik tells them not to talk, but they do anyway. Kate asks Jack what he meant earlier when he said that they needed to put things back the way they were supposed to be. Jack says that if they can do what Daniel said, Oceanic 815 never crashes and all of the people that have died since they got to the island would still be alive. Kate asks "And what about us? We just... go on living our life because we've never met?" Jack says that all of the misery they've experienced would be wiped clean. Kate says "It was not all misery" and Jack replies "Enough of it was." Kate has tears in her eyes at this point.

Eloise walks in and asks what Daniel needed the bomb for. Jack says "I don't think you'd believe me if I did." Eloise tells Jack that when she was 17 years old, she took Daniel to the bomb where he told her if they buried it, things would be okay. She says that Daniel told her he was from the future and then disappeared before her eyes. Before Daniel died, he told her that she was his son. She says that if he explains things to her that she will believe him.

She then pulls out Daniel's journal and asks "How is this my handwriting if I don't remember writing it?" Jack says "Because you haven't written it yet." Jack tells Eloise that he thinks that if they can it all back and Daniel will not be shot. He says that if they do what is in that journal, none of this will have happened. Eloise turns to Kate and asks "Does he know what he's talking about?" Kate says "He thinks he does."

Eloise says that she'll take them to the bomb, but they buried it over 20 years ago and now there's a village over it. The Dharma barracks were built over where Jughead is buried. Eloise says it should be simple since they have been passing themselves off as members, but Jack says that it'll be more complicated than that.

Kate seems to be leaving out here that if Oceanic 815 doesn't crash, she'd be in jail for killing Wayne. I do believe that her emotions about the island experiences are real though. Jack is determined to change things though and is willing to sacrifice knowing Kate to have never experienced the island. Something tells me that things won't work out exactly how Jack wants them to though.

Richard Alpert works on a ship in a bottle, Locke returns to lead the others

In 2007, the others have set up camp on the beach. We see Richard Alpert under a tent/canopy working on a ship in a bottle that looks similar to the Black Rock (see the photos of the Black Rock painting here, but it does look similar to the photo from the Lost Experience here).

An other named Vanessa runs over and tells Richard "he's here." Richard gets up and sees John Locke walking into camp with a dead board on his back. Locke says "I brought dinner." Richard seems stunned and says to Locke "It's been three years" and then asks what happened. Locke tells him that he'll explain on the way and says they have an errand to run and they don't have a lot of time. Richard is staring at Locke and Locke asks "What's wrong?" Richard says "There's something different about you." Locke leans in and says "I have a purpose now." Sun and Ben then walk into the camp and Richard asks what Ben is doing here. Locke says "He helped me get back."

Sun asks Ben why Locke said that these are his people. Ben says that Locke became the leader after he left the island. Sun asks Ben who Locke is talking to. Ben says that it is Richard Alpert who acts as an "adviser" and that he's had that job for a "very, very long time." Sun grabs the Dharma recruit picture and runs towards Richard and Locke. Ben seems concerned that Sun is approaching Richard and he calls her name.

Sun asks Richard if he was here in 1977. She shows him the picture and asks again if he was there and if he remembers any of them. Richard says that he was here thirty years ago and he clearly remembers meeting them because he watched them all die.

So there is something different about Locke and I think we can trust Richard's instinct when he points it out. What did Locke's resurrection change in him or is he not truly alive? Was Ben right we he said "Dead is dead?"
