- After buckling over a tree root, Malorie becomes separated from Boy and Girl. While she manages to find Boy, Girl is being tempted by the creatures to remove her blindfold. As she tries to call out to her, Boy tells her that Girl is afraid of her. Realizing how harsh and cold she's been to her children, particularly Girl, Malorie calls out to her and apologizes and affirms her love for her.Malorie: Oh, I'm so sorry. I'm so sorry, sweet girl. I'm so sorry. I was wrong. I shouldn't have been so harsh. I shouldn't have stopped you from playing. I shouldn't have ended Tom's story because it wasn't finished. When he climbed to the very top of that giant oak tree, he saw the most beautiful things. He saw hundreds of children playing games. Hundreds. And he saw birds... all different colored birds, and... and he saw us. He saw us from the very top. He saw us together, and we have to be together. And it's not just a story. It's not, because I have so much I want to show you. I have so much I want you to see. Okay? But we have to do it together, okay? So I just need you to come to me right now, okay? Please? Just come to me. Baby, come to me, okay? I love you so much. I love you so much. I love you so much. I love you so much.
- Doubles as a Tear Jerker: Olympia's last act is to hand over her baby for Malorie to keep safe before she succumbs to suicidal madness.
- As much of a self-centered Jerkass as Douglas had been throughout the movie, he ends up dying a noble death, fighting Gary to protect Malorie and the babies even though he had the chance to save himself. He had a Hidden Heart of Gold after all.
- The Hello Kitty keyring that Malorie gives Olympia as a gift.
- At the end of the film, after five years, Malorie finally names Girl and Boy - Olympia and Tom.
- When Malorie is contemplating which one of the children is gonna have to risk being the lookout to help her get them to land it seems pretty clear she is going to choose Girl, who sweetly if not understandably tearfully tells her she'll do it. Cue a flashback to Olympia (Girl's actual mother and who was arguably one of the most compassionate and kindest of the group) and Tom, who sacrificed himself to save her and the children, and it is with this that Malorie decides to steer herself rather than risk either one of the childrens safety.
- Malorie and Tom's entire relationship throughout the movie. He treats her with respect and kindness from the beginning and she quickly warms up to him. They seem to become each other's rock and main source of stability in all the insanity happening around them. After the time skip, Tom and Malorie are clearly deeply in love with each other and have essentially formed a family unit with the two children. Makes his death near the end all the more heartbreaking.
