Sun is frightened of Locke when they arrive at St. Sebastian's

In the flash sideways Locke is in an ambulance with a paramedic and Ben being rushed to the hospital. Ben tells the paramedic that Locke is a paraplegic, but he doesn't know anything else about him. Ben says that he saw the man who hit Locke and the paramedic says that he can talk to the police at the hospital.

Ben says he doesn't know who to contact for Locke, when Locke weakly says the name Helen Norwood. He also says that he was going to marry her. Ben tells Locke that he'll still marry her because he's going to be okay.

Once they arrive at the hospital, an ambulance carrying Sun and Jin arrives too. Sun and Locke are wheeled in right next to each other when Sun looks over and sees Locke. Sun freaks out, repeating "It's him!"

So it seems that Sun has had a vision of the original timeline, since she recognizes Locke and is afraid of him. It's all seems to be coming together now.

Fake Locke tells Jack that he was Christian on the island

At Locke's Camp, we return to the stare-down between Locke and the group Hurley led there. Locke tells Jack that he was hoping he would come and says that have some catching up to do. Jack asks Hurley if it's okay that he talks to Locke alone, since it was Hurley's plan to come there. Hurley says to go and Jack follows Locke into the jungle.

Once Jack and Locke stop to talk, Jack says that he looks just like Locke, but he has no idea what he actually is. Locke says that Jack does know, prompting Jack to ask why he looks like John Locke. Locke says he took the form because Locke was stupid enough to believe he was brought to the island for a reason, which led to his death, and then Jack was nice enough to bring his body back in a box. Jack asks if Locke had to be dead before he could look like him, and Locke says yes.

Jack asks who else he has looked like and Locke tells him to ask what he really wants to know. Jack says that on the third day he was on the island, he saw his father, and asks if that was him (fake Locke). Locke says that he was Christian and he took that form to lead Jack to water and that all he's ever done is to help him leave the island because Jacob trapped them there, but now they can leave. Locke says to leave though, they have to all go together.

Jack says that real Locke was the only person who believed in the island and did everything to keep them from leaving. Fake Locke says that Locke was not a believer, but just a sucker.

So how much of what Locke says is true? I certainly believe he was Christian, but he is likely lying his motives. This is certainly not the last big conversation Jack and Locke will have.

Desmond runs into Locke with his car at the high school

Back in the flash sideways world, Desmond sits in his car at the school where Ben and Locke work and watches as Locke exits the building in his wheelchair.

Ben comes over and knocks on Desmonds window and asks him a series of questions about what he's doing there. Ben says that he's been parked there watching the kids for a while. Desmond says that he's there looking for a school for his son, and when Ben asks for his son's name, Desmond says Charlie. It seems clear here there Desmond remembers his son from the original timeline, though one could say that's just the first name that popped in his head.

After Ben leaves, Desmond watches Locke start to cross the parking lot and accelerates his car toward him. Desmond hits Locke, who hits the windshield and the flies over the top of the car and lands on the ground. Desmond speeds away as Ben runs over to help Locke who is once again lying bloody on his back.

The look on Locke's face is similar to when he was on the ground after Anthony Cooper threw him out of the window. Will this be Locke's moment of clarity where he remembers the original timeline like Desmond, Charlie and Hurley?

And the big question is, why did Desmond do this? Was he trying to kill Locke or was he trying to push him towards Jack at the hospital? This seems to be similar, yet a more forceful version of what he did pushing Hurley towards Libby during their conversation at Mr. Cluck's. What does Desmond know?!

Hurley's group arrive at Locke's camp, Jack & not-Locke meet

Locke returns to his camp to find Sayid waiting for him. Locke tells him that Desmond won't be a problem anymore. Sawyer then begins to chastise Locke when he stops cold as he sees Hurley walk into camp.

Locke looks pleased to see Hurley. Hurley says that he doesn't know who Locke is, but there are other people with him and they just want to talk without any violence.

Hurley tells everyone else to come out and Frank, Sun and Jack emerge from the jungle. Kate and Jack look happy to see each other, but then Locke says hello to Jack. They share an intense look.

This is the first time Jack has seen Locke since he put the shoes on him at the butcher shop before boarding Ajira 316.

Locke throws Desmond down an electromagnetic well

Locke and Desmond's journey comes to an end at an old well, but not the one near the Orchid Station where Ben and Locke turned the frozen donkey wheel. Desmond looks down the well trying to guess how deep it is and Locke throws a torch down that hits the bottom.

Locke tells Desmond that this well is so old that the people who dug it did it completely by hand. He says that these people dug it to understand why their compass needles spun uncontrollably at this particular spot, but they never found what they were looking for.

Locke continues, saying that he showed Desmond this well because Charles Widmore is only interested in power, not answers and he plans to use Desmond to find what he's looking for. He adds that this is not the only well. These wells all seem to be built over pockets of electromagnetism, so is this what Zoe was asking Jin about? Do they need Desmond to survive another Swan Station or Incident-style blast?

Moving on, Locke asks Desmond why he's not afraid to be out here with him considering no one knows they're there. Desmond says "What's the point in being afraid?" Locke's expression turns sinister and he throws Desmond down the well.

So there's still the big mystery as to why Desmond is so zen now. We still don't know what he knows in either timeline.
