Inside the elevator at the hotel Kate tells Aaron to press number 31, the floor number where Sun is staying. 3+1=4; 4 is one of The Numbers.
Ben is told at the end of the episode that he has 70 hours. 70 hours in minutes is 4200 which contains 42, one of The Numbers.
Kate (to Sun): What kind of a person do you think I am?
Sawyer asked Kate that exact same question in the season 2 episode "The Long Con".
The ticket on the butcher shop that Ben took had the number 3-42. 42 is one of "The Numbers".
When Hurley ran towards the police officers, he said that he killed 4 people, and immediately said he killed 3 people (he made a mistake). 4 is one of "The Numbers".
The scene takes place in California but there's a sign for Windward Auto Spa located in Kaneohe, Hawaii, in the background.
In the gas station scene, all of the Oceanic Six appear or are explicitly referenced: Hurley and Sayid in the truck, Kate and Aaron in the SUV, Sun's voice on the cell-phone, and Jack's name on the cell's display.
The main device in Mrs. Hawkings's laboratory is a Foucault's pendulum. Umberto Eco used Foucault's Pendulum as the title for his novel offering a conspiracy theory to explain all human history.
Hurley's dad is seen watching Exposé, the show in which Nikki had a part.
Lapidus fetches two bottles of Jekyll Island Red Ale, a prop beer brand from Independent Studio Services also seen in the shows Dexter and Rules of Attraction.
The gauge on the oxygen cylinder when Jack is trying to revive Sayid includes the numbers 4, 8 and 15, three of The Numbers.
Jack's phone number on Kate's cell phone is 323-555-0156. It contains the number 23 in the first part and 15 in the middle of the last part, two of The Numbers.
Ben: Any luck?
Ms Hawking Yes, what about you?
Ben: I'm having some difficulties.
Ms. Hawking: Well, you better get busy, because you only have 70 hours.
Ben: What, no no, that's not enough time. What I need at least...
Ms. Hawking: What you need is irrelevent. 70 hours is what you've got.
Ben: Look, I lost Reyes tonight. So what happens if I can't get them all to come back?
Ms Hawking: Then God help us all.
Jack: (about Sayid) We have to get him to the hospital.
David: No. No. Hugo said that whoever did this, will come back after him.
Jack: All due respect, Mr. Reyes, but you brought him to me, so I'm gonna do what I think is best for Sayid.
David: All right, fine, take him to the hospital. But with all due respect for you, Dr. Shephard, when all this is over, you're gonna do something for me.
David: Stay away from Hugo. Whatever it is you talked him into, something tells me you don't have his best interest in heart. So stay away from my son!
Locke: James, Juliet. Nice to see you!
Hugo: Thanks, Ana Lucia.
Ana Lucia: Oh, yeah. Libby says hi.
Hurley: I'm a murderer. I killed four people. Three people. However many I did. I killed them.
Ben: I'm taking you to Sayid. He's with Jack. That's why I'm here, Hugo. Jack called me. How else would I know that they're together?
Hurley: No. You're playing one of your mind-games. They'd never trust you.
Ben: In their defense, I'm not an easy person to trust.
Sawyer: We should keep moving. We've got to hook up with everybody at the creek.
Juliet: It's a long creek, James. Which part?
Sawyer: I don't know. The wet part.
Carmen: And what did happen?
Hurley: Okay. You see, we did crash. It was on this crazy island. We waited for rescue and there wasn't any rescue. And then there was a smoke monster and then there were other people on the island, we called them the Others. And they started attacking us. And we found some hatches and there was a button you had to push every 108 minutes. Well, I was never really clear on that. But, the Others didn't have anything to do with the hatches. That was the Dharma Initiative. They are all dead. The Others killed them and now they are trying to kill us. And then we teamed up with the Others because some worse people were coming on a freighter. Desmond's girlfriend's father sent them to kill us. So we stole their helicopter and we flew to their freighter, but it blew up. And we can't go back to the island because it disappeared. So we crashed into the ocean and we floated there for a while until the boat came and picked us up. By then there were six of us. That part was true. But the rest of the people, who were on the plane, they're still on the island.
Carmen: I believe you, I don't understand you, but I believe you.
Hurley: A lot of people died, Ma. Now this bad stuff is happening because, well, we shouldn't have lied.
Carmen: Who is Sayid? I thought he was your friend.
Hurley: He is my friend. But he's also got this double-life where he does crazy ninja moves and spy stuff. But he's a good guy.
David: You killed three people?
Hurley: No. Sayid did.
David: Oh well, that's better.
Ben: John's casket is outside in a carpet van. I need to move it somewhere safe.
Jack: Safe? He's dead isn't he?
Jack: Where are we going?
Ben: You're going home. Find yourself a suitcase. If there's anything in this life you want, pack it in there. Because you're never coming back.
Ana Lucia: You were driving like a maniac. Why did you pull over?
Hurley: I just ... I thought ...
Ana Lucia: You didn't think. What if I were real? What if a real cop stopped you?
