While Penny and Desmond are discussing Desmond's search for Daniel's mother, there is a blue coffee cup on the nightstand next to Penny. When the scene cuts back to Penny, the cup is missing, and Penny's stack of paperbacks is rearranged.
Numbers: Miles senses the graves of 4 dead U.S. soldiers: 3 were shot and 1 died because of radiation poisoning.
Desmond and Penny's child is named Charlie, sharing a name with the man who kept them apart (Charles Widmore) and the man whose actions helped them reunite (Charlie Pace).
Daniel Faraday realizes he can't dismantle the Jughead bomb because it was leaking. In the season two finale (Live Together, Die Alone), Desmond mentions that "the incident" at the Swan station was the result of something leaking and needing to be covered in concrete. That is why there was a closed off (cemented in) portion of the hatch and the numbers that needed to be entered into the computer every 108 minutes to release the built-up electromagnetic energy.
In this episode, Daniel Faraday tells Ellie that they can render the bomb ineffective by covering it with concrete and burying it. In the season two episode, Everybody Hates Hugo, Sayid makes this statement about the closed off part of the Swan hatch: The last time I heard of concrete being poured over everything in this way was Chernobyl.
The main island events in this episode take place in 1954, approximately 50 years prior to when the plane crashed on the island.
Locke tells Richard he is born May 30, 1956, but in "Cabin Fever" we are introduced to Emily, John's mother while dancing to the 45 single "Everyday" by Buddy Holly and Crickets. The single for that record wasn't pressed and released until September 29th, 1957.
The Numbers: While at Oxford, Desmond goes to the Department of Physics located at Claredon 142-08.
The Oxford Physics Department is housed in Clarendon laboratory, not "Claredon" as it reads on the sign Desmond passes in the quad.
The claymore mines near the creek did not enter service until 1960, 6 years after the time period quoted (1954).
"Jughead" appears to be a Mark 16 nuclear bomb. The Mark 16 is more properly designated TX-16/EC-16 as it only existed in Experimental/Emergency Capability versions. Design yield was 6-8 megatons. Only five units ever manufactured, in January 1954, and deployed in an interim "emergency capability" role with the designation EC-16. By April 1954 they were all retired.
In Charles Widmore's office, there's a painting on the wall with "Namaste" written on it. "Namaste" being the Hindi salutation often used by people from the DHARMA Initiave.
Jughead was the code name for a bomb in the real-life Operation Castle nuclear test on Bikini Atoll. This test took place in March/April 1954. The bomb named Jughead was not detonated.
This episode reveals why Richard was at the hospital when Locke was born, and why Richard conducted an interview on Locke when he was a young boy, in previous episodes. Because Locke talked to him in 1954, before he was born.
When Penny gives birth her baby goes from her womb, to the doctor, to her arms in seconds with no umbilical cord being cut.
Ellie: (Upon seeing Daniel Faraday) You just couldn't stay away, could you?
Richard: How do I know you weren't sent here on some suicide mission? That I'll take you out to the bomb, and you'll just detonate it?
Faraday: Because... I'm in love with the woman sitting next to me. And I would never... I would never do anything to hurt her.
Sawyer: Are you crazy?! What were you thinking? Why didn't you shoot him?!
Locke: Because... he's one of my people.
Daniel: Charlotte! You okay?
Charlotte: Yeah. Fine.
Miles: Yeah, me too. I'm great too.
Richard: How did you escape?
Widmore: I ran.
Richard: And it never occurred to you that they might follow you?
Widmore: Follow me? Their leader is some sodding old man (referring to Locke). What, you think he can track me? Do you think he knows this island better than I do?
Miles: A hydrogen bomb. Seriously?
Daniel: Back in the fifties, the US government tested H-bombs in the South Pacific.
Miles: Lucky us.
Sawyer: Who taught you Latin?
Juliet: Others 101. Gotta learn Latin. Language of the enlightened.
Sawyer: Enlightened, my ass.
Miles: We're so dead.
Daniel: Hey, we're not so dead. We're going to be fine. We just need to keep it together until there's another flash, alright? Then all this disappears.
Miles: When's that going to happen?
Daniel: Could be 5 minutes. Could also be 5000 years.
Miles: That's just awesome.
Locke: (talking about Cunningham and Jones) And how is it that they know how to speak Latin, Juliet?
Juliet: The same reason I do. Because they're Others.
Sawyer: Who cares about the rifle? Where the hell have you been?
Locke: If you'd been going through what I have, James, maybe the more appropriate question would be, when the hell have I been.
Charlotte: You didn't have to say that.
Dan: Say what?
Charlotte: That you loved me. I mean there are plenty of other ways you could have convinced him you weren't going to blow up the entire island.
Dan: I said what I said because I meant it, Charlotte.
Cunningham: That idiot shouted out 'Meet at the creek'. We knew exactly where they were headed. Sent a group after them.
Sawyer: Maybe I should've said it in my secret language.
Locke: Who are these people?
Sawyer: Well gee... I didn't have time to ask that with Frogurt on fire and all.
Penny: If you're going to promise me something Des. Can you promise me you'll never go back to that island again.
Desmond: Pshhhht.. Why in God's name would I want to go back there.
Dan: Hey, hows your headache?
Charlotte: Worse, actually. But considering we're running for our lives I'm not going to complain.
Dan: Have you had any dizziness or double vision?
Charlotte: Both actually..... Why do you look so worried. Is it because you know whats happening to me?
Miles: Sawyer said to meet at the creek. So, unless he got torched by a flaming arrow that's where he and everyone else should be.
Penny: You also left out the bit about his grandfather. The man who sent a boat to the island to kill all Daddy's friends.
Richard: I said put the gun down Widmore.
Locke: You're name is Widmore? Charles Widmore?
Charles Widmore: What's it to you?
Locke: Nothing. Nice to meet you.
Locke: And because I'm your leader.
Richard: You're my leader?
Locke: That's what you told me.
Richard: Well, look, I certainly don't want to contradict myself.
Charles Widmore: Don't put Penny's life in danger.
Charles Widmore: You're getting yourself involved in something that goes back many, many years.
Dan: What, you're gonna, you're gonna shoot me? That right. Yeah, that would be perfect because of course rifle fire right next to - what would you call this, hydrogen bomb, yes, fantastic idea. Really inspired.
Ellie: Why do you keep looking at me?
Dan: Oh, no. I'm,I'm not. I...
Ellie: You are.
Dan: You know what? You're right. I'm, I'm sorry. It's just...you looks so much like...someone I used to know.
Ellie: Someone other than the girl you just professed your love for? Well, aren't you the Romeo?
Dan: Far from it. Believe me.
Ellie: I don't believe you, by the way. You may have Richard fooled, but you can't reallyexpect me to believe that you, a British woman and a Chinese man are all members of the United States military. Who are you and what are you doing on our island?
Dan: You want toknow who I am? I am your best chance at disarming that bomb.
Ellie: All right, then. Disarm it.
Locke: How did you know Richard would be here?
Juliet: Richards' always been here.
Locke: How old is he?
Juliet: Old. Why are you so interested in Richard, John?
Locke: I'm interested in him because he was about to tell me how I could save us.
Sawyer: What about you? Wanna stay here in crazy town or help me rescue the geek.
Desmond: Look, right over there, [the only way you can see this?], and it's a very special island, I left it a long time ago, I never thought I'd see it again; and it's called...Great Britain.
