The Losties move back in time, the hatch is not destroyed

Sawyer, Juliet, Daniel, Charlotte and Miles move backwards in time to before the Swan station/hatch imploded. Juliet uncovers the hatch much like Locke did in season 1.

Something I noticed when the sky got bright when they moved back in time is that Miles reaction seems more painful than everyone else. Maybe it's just the way he interpreted the moment, but it may be worth noting.

Richard Alpert comes to help Locke, gives him a compass

After John Locke moves forward in time, he goes to the plane and uses a belt to put around his bullet wound. While in the plane he sees more Virgin Mary statues and one of the charred bodies. Richard Alpert pops out of the jungle with a torch and a Dharma first aid kit from The Staff station. When Locke tells him that Ethan shot him, Alpert says "What goes around comes around." When Locke asks how he knew where to find him and that he was shot, Richard says that he told him, or rather he will tell him. Richard cleans Locke's wound and pulls the bullet out. Hell tells Locke that the next time they see each other, that he won't recognize Locke. He then gives Locke a compass and when Locke asks what it does, in another great line Richard says "It points north John."

He tells Locke that he has to get his people back to the island in order to save the island. Richard knows that the helicopter didn't go down with the ship and that everyone made it home. How he knows this is a mystery. Then the bombshell. Richard tells Locke "You're going to have to die John." Locke's reaction to this is the 13th image down.

Locke then goes back to the past, seemingly around the same time as before because the yellow beachcraft is still on the cliff and smoking. Locke then looks at the compass which is not the same one that Richard tested him with as a child (see those screens here).

So many questions here. Why does Locke have to die? How will he get off the island? When did Locke tell Richard that he'd been shot? What's the significance of the compass? Also, does it seem weird that Richard wears reading glasses? I guess Ben did too, but I guess the island has bigger fish to fry than taking care of people's optometry needs.

The losties visit the imploded hatch

After moving forward in time, Daniel, Sawyer, Juliet, Miles and Charlotte visit the remains of the imploded hatch. I've enhanced the dark photos so we can see more details in the shots.

Sayid kills two men at the "safe house," Hurley implicated

Sayid and Hurley stop at the Rainbow Drive-In to get Hurley some food before proceeding to the "safe house." Sayid reveals to Hurley that he was working for Ben, but no longer is. He tells Hurley to "do the opposite" of anything Ben tells him to do.

The "safe house" turns out to be not so safe. Sayid notices that his tape above the door is ripped. He proceds into the room and is attacked by a man who he then throws off the balcony. He is then attacked by another man and they struggle. The man shoots Sayid with darts before he is impaled on some knives in the dishwasher. Hurley grabs the first man's gun and looks over the balcony. Some men below take his picture and he appears to have blood on his shirt though it's actually ketchup.

Who are these men that are watching Hurley and attacking Sayid? They obviously didn't want to kill Sayid otherwise he would have shot him instead of using a dart gun.

Ben and Jack see the news report about Hurley

While at the hotel/motel, Ben and Jack see the news report on Action 8 News about Hurley escaping from Santa Rosa Mental Health Institute. This causes the Ben to change their plan of action.
