Aired Sunday 9:00 PM Apr 06, 2005 on ABC



  • Trivia

    • Black and white ("Lost"'s recurring theme):

      In Jack's flashback when he is talking to Marc, the T-shirt he is wearing has a yin yang symbol on it.

    • When the baby is born, Kate doesn't clear his nose or mouth as Jack instructed her.

    • Only four people (according to Charlie) know their blood type. 4 is one of the numbers.

    • In Jack's flashback at his wedding, his best man is Marc Silverman, the boy from his childhood, who he is shown trying to help in "White Rabbit"

    • This is the first episode of "Lost" to have a main character die.

    • Numbers: 4

      When Jack and Sarah are sitting at the piano, she is wearing a shirt with two 4s on it.

    • Numbers: 8

      As Jack is adjusting Marc's tie, Marc says that he'll be fine after 8 beers.

    • Island events in this episode take place on November 2nd 2004.

    • In flashbacks Jack marries a woman named Sarah, who he saved after she broke her back in a car accident.

    • When Flight 815 first crashed, there were 48 survivors by the end of the pilot episode. In "Tabula Rasa," the U.S. Marshall died, leaving 47, a character named Joanna died in "White Rabbit," leaving 46, and the murder of Scott by Ethan in "Homecoming" left 45 survivors. Boone's death in this episode leaves 44. In a flashback, Jack's fiancée, Sarah, is wearing a t-shirt that has a rather large '44' on both the front and back.

    • In the flashback to the tuxedo shop, Jack doesn't have the elaborate tattoo on his shoulder yet.

    • In episode 11, "All the Best Cowboys Have Daddy Issues," Boone and Locke are tagging trees with red shirts to make a trail. Boone mentions that the Star Trek team members who got killed every episode wore red. Now that this episode has happened, it seems like it was a premonition about Boone's death.

    • When Sun says that Jack can't save Boone, Jack angrily shouts "Don't tell me what I can't do!" These same words were said in much the same tone by Locke in the episode "Walkabout."

    • The song that Jack and Sarah play on the piano is "Heart and Soul", which was written in 1938 by Hoagy Carmichael.

    • In this episode, Boone tells Jack that he is "letting him off the hook" because Jack promised he wouldn't let Boone die. Rose said the same thing to Jack in the episode "Walkabout" because he had promised before the plane crashed that he would keep her company until her husband returned from the restroom.

    • Jack gives blood to Boone from his left arm, which is later bandaged. After Claire shows her baby to the survivors, Jack is seen packing his bag on the beach (for a split second) from a distance as Kate approaches him and his bandage is now wrapped on his right arm. As he and Kate talk, his left arm is bandaged again.

    • Charlie was right: delivering a baby is quite simple, but if they did it the way Jack told them to there would have been some injuries to Claire to attend to. (And it could have taken dangerously long if Claire could follow the instructions) He told them she shouldn't push too hard until the baby's head is out and then push as hard as she can. It should in fact be the opposite.

  • Quotes

    • Boone: (last words) Tell her i....

    • Sarah: Those girls are checking you out.
      Jack: You're in your pjs.
      Sarah: Indeed, I am.
      Jack: Are they cute?
      Sarah: Who?
      Jack: The girls who are checking me out.
      Sarah: Mmm... One of them's kinda cute. The other one's just trashy.

    • Shephard: (about Sarah) You love her?
      Jack: Absolutely.
      Shephard: Then why are you sitting out here?
      Jack: What if I can't be the husband or the...or the father that I want to be? What if I asked her because, because I saved her life? Should I marry her, Dad?
      Shephard: Commitment is what makes you tick, Jack. The problem is you're just not good at letting go.

    • Jack: (to Boone) You are not gonna die. I'm gonna fix this, ok? I am going to save you.

    • Kate: Where's Jack?
      Charlie: Couldn't come.
      Kate: What do you mean he couldn't come?
      Charlie: He's pouring his own blood into Boone's arm right now.

    • Shannon: I need to tell you something.
      Sayid: Alright.
      Shannon: My brother, Boone. He's not really my brother. He's my step-brother. Our parents got married when we were, like, 8 and 10. He's kind of in love with me.
      Sayid: In love with you? And how do you feel towards him?
      Shannon: I'll always feel something for him. But am I in love with him in that way? No. Not at all. We're here for God knows how long, and so is Boone.

    • Sawyer: You need anything else? I could come with you.
      Kate: Too many cooks already, but thanks.

    • Sawyer: Hey, mamacita. You want some fish?
      Claire: No, thanks. I'm not really hungry. (about the raft) How long do you think 'til it's ready?
      Michael: Maybe a week, maybe less. You okay?
      Claire: Yeah, I'm fine. Alright, I'll see you guys later.
      Sawyer: She likes me.

    • Kate: Boone died, Jack.
      Jack: He didn't die. He was murdered.
      Kate: Where are you going?
      Jack: To find John Locke.

    • Claire: You know I was out there for over a week...days I can't remember. I mean, what if, what if they did something to the baby? I'm not ready for this. I'm not... I'm so scared. I'm scared.
      Kate: I'm, I'm scared, too. But we're going to get through this together, okay?

    • Boone: (between raspy breaths) I know you made a promise. I'm letting you off the hook. Let me go, Jack.
      Jack: I'm sorry.
      Boone: Don't be.

    • (Jack has given blood to Boone and is very pale)
      Hurley: Dude, are you okay? You look goth.

    • Jack: (on Charlie's scant collection of responses to the "blood type" question) You only asked four people?!
      Charlie: I asked the whole sodding camp! Nobody knows their blood type! Most don't know their blood type! I don't know my own bloody blood type!

    • (We see Claire in labor)
      Kate: Claire, I think this is about the time you're supposed to start pushing, okay? So, push.
      (Claire holds her breath)
      Kate: Don't hold your breath, honey. You won't be able to push if you—Claire? Claire, what are you doing? Oh, no, no, no, Claire, you need to push, right now. Don't do this, Claire, okay? You can't stop this—this is happening. Your baby is coming and I need your help.
      Claire: It's not going to want me.
      Kate: What?
      Claire: It knows I don't want it—that I was going to give it away. Babies know that stuff.
      Kate: Do you want this baby now? Hmm? Do you want it to be healthy and safe? (Claire nods) Okay, then the baby knows that, too. You are not alone in this. We are all here for you. This baby is all of ours, but I need you to push, okay? Okay? Alright. One, two, three, push. Good. Good, push.

    • (We see Kate running through the jungle. She hears some moaning and finds Claire)
      Kate: Claire? What are you doing out here?
      Claire: Nothing. Just leave me alone, please.
      Kate: Oh God, you're having the baby!

    • Sawyer: (speaking about Jin) The man's got what I call an overzealous work ethic.
      Michael: Try obsession. He wants off this island bad, man.
      Sawyer: Can't say I blame poor Kato. His lady speaks English all this time and he didn't have a clue? I'm surprised he didn't try to swim out of here. Hell, I would've.

    • Shannon: Oh, okay. Are you lost?
      Sayid: No, absolutely not. Those trees look really familiar. It's this way...I think.
      Shannon: Did you just say 'I think'?

    • Jack: You know why they call it a tie? Because you have to tie it.
      Marc: You know why they call it a clip-on? Because you have to clip it... on.

    • Charlie: That dilating thing. How do I look out for that?

    • Sarah (toasting Jack): Because you are the most committed man that I have ever known. Because...you fixed me... I will dance at our wedding. To Jack... my hero.

    • Jack: Don't tell me what I can't do!

    • Jack: Hurley, I swear to God, if you faint-!
      Hurley: No. First-class, mesh. I'm cool. Lord in Heaven...

    • For the first time, Terry O'Quinn (Locke) didn't appear.

    • Lost executive producer Damon Lindelof has said Boone's death was crucial to the plot because it intensifies what the show is about - the conflict between heroic doctor Jack and enigmatic, potentially menacing Locke.

    • Despite the producers releasing actor Ian Somerhalder from the role of Boone as his character died, ABC made the blow for the actor a little easier when they signed Ian Somerhalder on a new one year talent holding deal at the network to star in another project.

    • Actor Ian Somerhalder was told by the producers in late January that his character Boone was going to die in an upcoming episode, which was a huge mystery at the time among show fans when the news of a main character dying soon leaked out.

    • The episode title, "Do No Harm" is the Hippocratic Oath that all doctors must take. In this case, Jack.

    • A Jack-centric episode.

  • Allusions

    • This episode is reminiscent of the music video Lightning Crashes by Live, which depicts a birth and a death happening simultaneously.

    • Sawyer refers to Jin as "Kato" in a politically-incorrect reference to either television's The Green Hornet or the movie The Pink Panther and its sequels. Both the Green Hornet and Inspector Clouseau had Asian assistants named Kato.
