"Previously on Fringe:" "You nearly died when you were a boy." "I became consumed with saving you." "Walter, I don't remember any of that." "OBSERVER:" "There is more than one of everything." "I have said too much." "I am not supposed to get involved." "What did you people do to us?" "Of the children Bell and I experimented on you were the first to identify things from the other side." "Was it me who described it as a glimmer?" "I've never met anyone who can do the things that you do." "I'll go get my coat." "Please don't tell him." " Serve as an example of our ability to achieve that which most can't even imagine." "But what you must understand is that as scientists we must embrace every possibility." "No limitations." "No boundaries." "There is no reason for them." "Gentlemen, I would like you to take a look at this." "It's a mobile telephone." "Can be made much smaller, I assure you." "Does this work?" " Not here." "Not yet." "This phone is digital, not analog." "It'll take us 30 years to get up to speed." "I didn't invent it." "I wish I had." "Dr. Bishop, we were under the impression Dr. Bell would be here." "I'm afraid that's not possible." "Dr. Bell is in Europe." "But I am here, so I can answer any questions you may have." " Dr. Bishop, is this Russian technology?" "It is not." "It is quite American but it is technology from another universe." "An alternate universe just like ours, but more advanced in some areas." "Are you suggesting you somehow visited this alternate universe and acquired this technology?" " No." "It is theoretically impossible to go there." "Then how did you come to possess this?" "I copied it." "For the last several years, William and I have been conducting experiments regarding this other universe." "So based on our findings, we developed a window of sorts a way of looking in to this neighboring world." "And that is why we are asking for funding." " This is my colleague, Dr. Carla Warren." " Hello, sirs." "This window works by capturing errant photons from the universe beside ours." "The window essentially stretches the membrane between our worlds and allows us to see their image from our side." "You're gonna make some sort of alternate Manhattan appear?" "It's already there, General Hayes." "Dr. Warren." "At all times." "Right in front of our eyes." "We just can't see it." "I'm sure you know that the original purpose of the so-called observation deck of the Empire State Building was to be a docking station." "For zeppelins, of course." "Gentlemen, you are looking through a window into another world." "Walter, what are you doing here?" "You left me no choice." "You wouldn't answer your telephone or return my messages." "I tried to communicate." "Well, I need time, okay?" "I don't even know how to begin to work this out." "I think I do." "Please, Olivia." "I need to explain." "If you wouldn't mind, I could use a sip of something myself." "Have you told Agent Broyles?" "No." "But to be honest, that doesn't mean that I won't." "I always knew that one day I'd have to pay the price for my deception." "Well, we're not really sure what the cost is yet, are we?" "No, I suppose not." "I invented this after William and I learned that we had doubles on the other side." "Or maybe it was before." "I can't remember." "It's a window to the other universe." "I was a different man then." "I was going to change the world." "But, you see, after Peter became sick none of that seemed to matter anymore." "The illness was genetic." "Savage." "Wasting." "I tried everything." "There was simply no hope." "At least not on this side." "But over there, they were more technologically advanced." "If the alternate Peter was also sick, over there then wouldn't his father be equally motivated to find a cure?" "He was." "God help me." "He was." "Any progress?" "He's synthesizing a new compound now." "He's using cobalt and magnesium." "Any idea yet how he's selecting the filtering compounds?" "Random, I think." "Chance." "Fate." "Luck of the draw." "I've given him a name, Carla:" "Walternate." "This should be the reaction." "No cure." "Perhaps with a higher iodine purification." " Walter Bishop." "Walter." "Elizabeth." "Is he...?" "Yeah, no, he's fine." "He's all right right now." "What?" "I think you should come home now, Walter." "I think it's time you came home." "Okay." "Okay." "He looks worse." "He keeps asking for you." "It's not like before." "What is it like?" "It's different." "He keeps saying he wants to talk to you." "He says he's worried he won't be able to..." "I just can't bear it when you're not here." "You know what I'm doing." "You know where I am." "Twenty-four hours a day, seven days a week." " Yes." " I won't give up, Elizabeth." "I can do this." "I need you not to doubt me." "You're supposed to be getting some rest, my son." "Look, Dad." "I've almost got it." "Oh." "Let me show you." "Now:" "Slowly." "Watch." "One finger at a time." "Let me show you." "Very good." "I want you to have it." "My lucky silver dollar." "If I die." "Peter." "It's okay." "I'm not scared." "Nothing is going to happen to you." "I promise." "You're going to be just fine." "Okay?" "Now, get some rest." " Okay?" " Okay." "Will you wake me for dinner?" "I don't wanna miss it." "You're not gonna miss anything." "You know how much William wanted to be here." "What with the meetings in Berlin..." "I don't need to tell you how important they are for both of you." "He wanted me to make sure that you know how terrible he feels." "Yes." "I understand." "I'm glad you came." "We didn't give him a good life." "We didn't." "He practically never got out of the house." " He was always too sick." " He didn't go to a proper school." "He didn't have any proper friends." "He had no family but us." "We kept him so well we never let anyone else get to know him." "We did the best we could." "We dealt with what we were given." "He knew he was loved." "Didn't he?" "Walter, what's wrong?" "You're cold." "Have you been outside?" "Come with me." "What all is this?" "How is this possible?" "How are you doing this?" "What I've been working on, Elizabeth." "It's a window to another universe like ours, but different." "Please." "Please turn it back on again." "Please turn it on." "I want to see him again." "Elizabeth, I'm showing you this because I want you to know that somewhere Peter will grow up, somewhere he will lead a proper life." "Somewhere he will be happy." "But just not here." "And that we must take comfort in this." "And we must begin to move on." "The compounds you're using for the cure." "Not random at all." "You are very, very smart." "Yes!" "You did it!" "My God, you did it." "Ha." "No." "No, no." "You had it." "The cure." "All you have to do is stabilize the compound, and you can save him." "You can save him." "MAN 1:" "Their theories are fascinating." "MAN 2:" "They are not theories." "They are entertainment." "I have made a mistake." "So I've heard." "What were you doing in the lab?" "Dr. Bishop was on the verge of developing a cure for the boy." "It was an important moment." "He discovered me." "There was no other way to witness the moment." "You have changed the future." "You have created a new set of probabilities." "But you must agree the moment was significant." "The boy is significant." "You need to take action to restore balance." "How?" "You will have an opportunity to fix this." " Walter?" " Dr. Warren." " Have you been here all night?" " I've been working." " Working on what?" " This." " What is this?" " Walternate found a cure." "He found a cure for Peter." "And it worked, Carla." "It's not too late." "I can save him." "Walter, Peter is dead." "I know." "Of course I know that." "I'm not talking about my Peter." "I'm talking about the other Peter." "The one on the other side." "He missed it." "The other Walter." "He missed it, you know." "It was right there, in front of him, and he didn't see it." " He was distracted by the man." " What man?" "The man in the lab." "He was distracted and when he returned, the positive result had failed and so he moved on." "Maybe he'll realize what he missed and go back." "Carla, he's just like me." "I wouldn't look back, and neither will he." "He didn't see the compound, but I did." "And I've reproduced it." "It just needed minor modification." "Without this, Peter will die." "He'll die all over again, which is why I have to go over there." "What?" "The Casimir effect should produce a thinner more porous region of space-time." "I only need to affect the area for long enough to cross over to the other side with a vial of the cure." "And then, of course, re-create the effect to cross back again." "Walter, you're trying to create a wormhole into another universe?" "Yes, I think I just said that." "Where's my map?" "When I looked into his room on the other side I saw that his mother had already packed his suitcase for our lake house." "Just like we do every year at this time." "That's where we need to find a location to set up." "Walter, I'm sorry, but you can't." "Yes, yes." "I think I can." "No, Walter." "I mean you can't." "Shattering the wall between universes would rupture constants of nature." " We don't know that to be true." "It's why we've been lying to the military, telling them it's impossible." "There has to be a line somewhere." "There has to be a line we can't cross." "I had always considered you as a scientist, Dr. Warren despite your personal needs for religious claptrap." "I see I was wrong." ""I am become death, the destroyer of worlds."" "Don't you quote Oppenheimer to me..." ""Knowledge can't be pursued without morality."" "I may go to church, but I also have three degrees in theoretical physics and I am telling you you cannot do this." "We both know the amount of energy required to create a portal will forever ruin both universes." "For the sake of one life, you will destroy the world." "Some things are not ours to tamper with." "Some things are God's." "My son is dying, Dr. Warren." "I will not allow that to happen again." "There's only room for one God in this lab, and it's not yours." "The lake." "It's perfect." "The water will absorb the excess energy." "I won't be needing your assistance any further, Dr. Warren." " Walter..." " That will be all." "Walter's always been like that." "He often goes off on flights of fancy." "Even if he was serious the design is decades beyond anything we could imagine." "You don't understand." "He already has the design." "He's building it." "Oh." "Yes, Dr. Bell's room please." "Here." "Here will do." "See you've changed your mind, Carla." "Good." "I'm sorry, Walter." "You disappoint me, Dr. Warren." "Go home, Nina." "There's work to be done here." "Walter, don't do this." "I'll be there and back before you know it." "That's not the point." "We both know there's more to it than that." "I don't mean to say that creating a doorway between the universes is trivial I'm simply suggesting..." "If William were here..." "If William were here, he'd be applauding." " That's not true." " No?" " Why isn't he here?" " The funding, his schedule..." "He's in Europe chasing funding?" "Too busy to come and stop me from destroying the universe?" "How many times have you rang him today?" "Once?" "Twenty?" "How many times has he returned your call?" "Do you know how many times William's encouraged me to take this very risk?" "To expedite our espionage program?" ""Why simply take a peek into the other universe, Walter when you can go there?"" "Till now, he couldn't make me find a way to try to get there." "Until I had to find a way." " I don't believe that." " No, you wouldn't." "Because you don't understand him." "Like everyone else you're blinded by the charming manner, the air of intelligence." "The whole damn show." "All William Bell ever cared about was finding a way to increase the power and the wealth and the legend of William Bell." "Walter, regardless of what William wants or who he is I know why you're doing this." "I understand." "You know how much Peter meant to me." "And how difficult it will be for me to admit that he's gone." "But this this isn't the answer." "No." "I won't let him die again." "No, Walter, I won't let you do it." "Walter." "Uhn." "Uhn." "Nina." "Help me!" "Oh, no." "Oh, no." "ELIZABETH:" "Hey." "You're supposed to be getting some rest." "Look." "I've almost got it." "Okay, let's take a look." "I'm gonna show you, okay." "It's like this." "Okay, slowly." "One finger at a time." "Okay." "Slowly." "Two." "Three." "Good job." "Okay." "All right, love." "Now sleep, okay?" " Mom?" "I want you to have it." " Mm-hm." " What, darling?" " My lucky silver dollar." "Okay." "I want you to have it." "If I die." " Sweetheart..." " It's okay." "I'm not scared." "Listen." "Nothing is going to happen to you." "I promise." "You're gonna be fine." "You just need to get some rest now, okay?" "Okay." "Good night." "Dad?" "Hello, son." "Dad are you all right?" "Yes." "Yes." "ELIZABETH:" "Baby, who are you talking to?" "Walter?" "How...?" "What are you doing here?" "I thought you were working late at Cambridge." "I..." "Walter, what are you wearing?" "Where'd you get that coat?" "I think I've found a cure." "What?" "I think I found it." "A cure for him." " Are you certain?" " Yes, I believe so." "I need to take him back to Cambridge." "To the lab." "We have to leave now." "Yes." "Yeah, of course." "Um..." "Right, Peter, darling, get up." "We're gonna get you dressed." "Darling, let's get you out of this." "Okay." "Good boy." "Okay, let's go." "There's a good chap." "All right." "Darling, we have to go to Daddy's work." " Elizabeth, may I have a word, please?" "ELIZABETH:" "Mm-hm?" "Yeah, of course." "Put those on." " What is it?" " I think you should stay here." " What?" " The cure, there's still testing to be done." "It could take all night to find the right dosage." " Well, I can pack a bag." " No." "You haven't slept in weeks." "If it works, there could be many days and weeks of recuperation." "Peter will need you." "He'll need you to be strong." " Walter..." " No..." " I'm fine." " Please, Liz." "I need you not to doubt me." "Okay." "Okay." " Oh, God, he's burning up." " We should leave." "ELIZABETH:" "You take this for luck." " I love you very much." " Me too, Mom." "I'm going to be waiting for you right here, okay?" "Okay." "Go." "Bring him back to me." "I promise." "Are you warm enough?" " I'm cold." " Me too." "Just a little farther." "Where are we going?" "Why aren't we taking the car?" "We can't get where we're going in a car." "You're not my father, are you?" "Of course I am." "Who else would I be?" "And I'm going to make you all better." "Hold on tight, son." "We did it." "Is he okay?" " Who are you?" " Who are you?" " You're the man I saw..." " You're the man I saw in the lab on the other side." "...in the lab on the other side." "Your friend and the one who was injured." "They left to seek medical attention." "He won't live much longer." "You must fix him." "Your lab is six miles from here." "Can you drive?" "I think so." "Why?" "Why did you save us?" "The boy is important." "He has to live." "I just got off with the hospital." "Dr. Bell called in a team of specialists." "He has some thoughts on Nina's arm." "Thank you for coming in to help with Peter." " After all that happened." " Of course, Walter." " He looks better." " Yes, he's getting his color back." "Seems to be working." "You're going to return him." "Yes." "Once he's stabilized." "Good." " I'd like to go now." " Of course." "Thank you." "ELIZABETH:" "Walter." "You didn't come home last night." "I was worried about you." "I thought..." "How?" "He was dying, Elizabeth." "This is the boy I showed you." "The other Peter." "It was the only way I could save him." "Oh, God." "Oh, my baby." "Oh, my baby." "Elizabeth, don't." "He's not ours." "I have to take him back." "And I realized at that moment  that despite what I'd promised what I fully intended to do that I could never take Peter back." "The way she looked at him I saw in her what I feared most in myself when I saw him:" "That I couldn't lose him again." "It was the first hole, Olivia." "The first breach." "The first crack in a pattern of cracks, spaces between the worlds and it's my fault." "You can't imagine what it's like to lose a child."
