Mark realizes that he has brought belief in fairy tales back to people in the world who had only believed in logic before. He felt so connected to the children that he finally decided for sure that he was going to keep the children just as they were. If possible, he might even try to find more people with catalog children like him, and share his information. Finally, as Mark was going through a box owned by his father in his attic, he discovered a little tag. On the tag, it said "Unknown experiment." In his father's handwriting is "My son". Mark throws away the tag and it is hinted as he was going to ask Lady A to marry him.
