Despite attempts by the unbelieving FBI to prevent them, Noah and Emma use their psionic abilities to escape so that they can activate the portal. As they journey to the family beach house, where it all began, Mimzy absorbs a tear from Emma, thus providing the DNA required to restore humanity's corrupted DNA. Emma is almost sucked into the future with Mimzy, but Noah grabs Emma and pulls her out of the portal just as Mimzy is sent back to its own time. Following the transport, Noah's science teacher, who was present at the event, claims that he saw "numbers", a reference to a previous dream he had with numbers in it, which turned out to be the winning lottery numbers, but missed out because he never bought a ticket—thus exciting his fiancée about this second opportunity. Back in the future setting, Mimzy is returned to the future, and humans are finally able to restore their DNA, and abandon their then-necessary protective suits, and more importantly, repair the "mental corruption" that stripped most of them of their feelings toward each other. The teacher ends the story time and the children levitate and fly home. The world in their time has become a beautiful place, where humanity has integrated into the reconstructed ecosystems.
