He finishes the last stroke of some graffiti and hears his mother shouting from downstairs — then realizes she is not shouting, she is screaming. He runs down and finds her caught in some kind of vortex, being pulled somewhere he cannot reach. He tries to stop it and fails. The computer upstairs is still running. When he sits down at it, it pulls him through too. He wakes somewhere else entirely with a young girl looking down at him — someone who seems to know what has happened, and who may be the only path to finding his mother and getting home.
