When Allie is walking with John (in alien form), they appear to be holding hands. But if you look closely, you can see their hands aren't in contact.
Jeffries: (talking over the radio) I've got information about this girl. The one you've heard about on the news, the one you've heard about on this program and, as usual, you're not gettin' the whole story. This little girl, she's a piece of the sky, my friends. Have you been taken? Well, so has she. Have you had experiences beyond human comprehension? Same's true of Allie. This little girl, my friends, she may hold the key to an understanding of all that you've gone through. I mean, the government believes it. That's why Allie's not safe. Because they're not gonna rest 'til they have her in their hands where they can look at her, try to figure out what this is all about. That's why she needs your help. They can do what they do because they can do it in secret. They don't have to stand out there in the light of day. Well, if you're on the road tonight, I want you to turn your car toward the state of Texas. If you're in bed, I want you to get up and I want you to get dressed, because they're not gonna be able to touch her if there are witnesses. The government must be on the road already, but we have to get out there first to save this little girl. So many of you call me, e-mail me, write to me and you're starving for an answer. You wanna know why you were taken, you wanna know what this has all been about. We're gonna save one child, my friends, and doing so, we may just learn that answer.
Lisa: What do you think's gonna happen next?
John: Allie goes with us. We work with her, we help her to understand our part of the equation.
Lisa: That's never gonna happen. You still don't get it. This thing you saw in my grandmother, this compassion, our humanity, you still don't have a clue what that means. Allie is my daughter. She is 9 years old. I love her with all my heart and soul. You will never take her away from me.
John: She can't stay here, Lisa. She did too much. If she uses her power again, that part of her that's us, it will kill her. And you were right. Those people will keep coming after her, and she will do something to keep you or Charlie safe. It's the only place for her. That is what's next.
Lisa: No, it isn't. You've inflicted enough pain on this planet. It's over. Let it go. Go away.
Allie: I'm just a little kid. I didn't ask anyone to make me special.
Allie: Charlie. I'm glad you turned out to be my dad.
Charlie: I love you.
Allie: I love you too, Daddy.
Allie: I didn't ask for this! I want to be a little girl! I just want to be a little girl!
Allie: If I stay here, people will kill each other. I don't want that to happen because of me.
Lisa: Well, then, we'll go away. I told you we have a plan.
Allie: Where could we go? This would all just happen again.
Lisa: Allie. Aliie, listen to me. I am not gonna let that happen. We're gonna get Charlie and we're gonna get out of here. We'll figure out a way.
Allie: There's nothing we can do.
Lisa: We're a family now. We can try.
Allie: We're always a family.
Dr. Chet Wakeman: (To Mary, after his death) There's something I wanted to share with you. We're all so desperate for meaning, aren't we? All of us. You too, Mary, even if you think you're not. You want answers, and in that way, I think the aliens are gonna disappoint you. Here's the stone truth of it: They're still asking the same questions we are. No one is God here. We're all in the same boat.
(Two simultaneous, different conversations)
John, Alien Visitor: I'll try to put this in terms that you commonly use. I'm a scientist. We were all scientists. We came here to learn about your world. Our idea was to find out everything: your history, your biology, everything. We came here to learn. We're not that different from you, genetically, biologically. But what you call evolution has changed us. We see things in you that we no longer recognize in ourselves.
Dr. Chet Wakeman: What do we know? They're this energy that can manifest itself in different ways: as the beings we've seen, as their crafts, as our thoughts. There's no right or wrong about them.
John, Alien Visitor: The whole concept of right and wrong was... alien to us. The idea that the things we were doing were cruel...
Dr. Chet Wakeman: They have no concept of kindness or cruelty. No way of seeing beyond the 'oneness' of all that energy...
John, Alien Visitor: ...to the separateness, the uniqueness, your ability to hate, to love, to feel. You have compassion, as well as cruelty. We-we lack both. Or that is, the traits lie dormant...
Dr. Chet Wakeman: ...in their brains. Like the animal that lives far back inside all of us. But an experience of something basic can awaken that primitive thing.
John, Alien Visitor: And that's what happened. Your grandmother, Sally. She took me in and showed me a great kindness.
Mary Crawford: Something could've touched one of them, something small and simple, and awakened this sense of what was missing. Something gone and half-remembered.
John, Alien Visitor: And so our greatest experiment began.
Mary Crawford: Could they put it back, this thing that had been bred out of them for eons and eons?
John, Alien Visitor: Your emotional core, your strength, your feeling, and our more evolved consciousness. Could we bring these two together? If we could do this, we would have the next...
Mary Crawford: ...step in the evolution of life.
John, Alien Visitor: (looking at Allie) The experiment was an unqualified success.
(Mary is using her laptop, when a video file of Chet appears)
Chet: Hiya, Toots! I programmed this video file to send itself in twenty-four hours if I didn't delete it. I didn't delete it, so I guess you must've deleted me... Yeah, I sorta saw that one coming.
Allie: (narrating) My mother always talked to me a lot about the sky. She liked to watch the clouds in the day and the stars at night...especially the stars. We would play a game sometimes, a game called "What's Beyond the Sky?" We would imagine darkness or a blinding light or something else that we didn't know how to name. But of course, that was just a game. There's nothing beyond the sky. The sky just is, and it goes on and on, and we play all of our games beneath it.
Allie: (narrating) I don't know what will happen next. I don't know what I'm going to be, what I'm going to learn, but what I do know is this—life, all life, is about asking questions, not about knowing answers. It is wanting to see what's over the next hill that keeps us all going. We have to keep asking questions, wanting to understand. Even when we know we'll never find the answers, we have to keep on asking the questions.
Allie: (narrating) They will be coming soon, coming to try to stop what was going to happen next. But maybe they could be stopped. Maybe something could happen that would make it hard for them to do what they wanted to do.
Allie: (narrating) How do you let someone go? How do you understand that that's alright, that everything changes? How do you find a way for that to make you feel good about life instead of breaking your heart? The hardest thing you'll ever learn is how to say good-bye.
Allie: (narrating) People talk a lot as if the most important thing in life is to always see things for what they really are. But everything we do, every plan we make is kind of a lie. We're closing our eyes and pretending the day won't ever come when we won't need to make any more plans. Hope is the biggest lie there is, and it is the best. You have to keep going as if it all mattered, or else we wouldn't keep going at all.
