Diana visits Tom and Alana's house in the hopes of visiting and seeing her daughter again, Alana takes her into her fantasy world. A little while later Tom arrives to find Alana and Diana on the floor separated. Alana, groggy but conscious, tells Tom she thinks Diana is still in the fantasy. Normally, when someone leaves the fantasy world they let go, but Diana does not wish to let go. Diana is unconscious, and is sent to an Intensive Care Unit. Tom and Alana visit Diana in her fantasy world, and Diana estimates she has at least 3 to four weeks to spend in her fantasy before she would die, but that could be a lifetime in there.
In the ICU, Tom tells Diana that he has a plan that might be the stupidest thing he has ever done, and he wishes she was there to stop him. Tom visits a bridge above a river and ties a hangman's knot around his neck. Standing on the bridge rails and prepared to jump, he kicks off and begins to fall, but mid-air he is encompassed in a bright flash and appears in the dark room. He speaks to the woman who claimed to be Sarah; she tells him that they underestimated the bonds the children had made. Tom tells her to either return the children or put that knot back around my neck, as I'm done. She tells him that she needs to show him something and nods to a cubicle which lights up with a child inside it. The woman tells Tom that they have enemies who want the 4400 to fail in their mission, and that sending the children further back in the timeline was an attempt to combat evil. If they return the children all the good they have done will be negated. Tom asks if there is another way to combat the evil. There is, but it is a burden the people from the future had hoped to avoid placing on him. He agrees with her, the deal is something he will come to regret, and in a flash of light Tom is returned to the empty house Sarah brought Maia to, in his own time.
Walking into the house, Tom calls out so see if anyone is there, and notices an envelope addressed to him on a fireplace mantle. Walking up the stairs he notices Maia peeking out the door. Tom calls to her and she runs to him and cuddles him. The other kidnapped children joyfully leave their rooms asking if they can see their families.
