Marissa: Why now, Erik?
Erik: Kids...grow up.
There's a lullaby-like song that plays in the film's credits.
Dream...how I dream to feel Dream...how I dream to feel And everything will fill with light A golden sun would fool this night And all that is, and ever was Begin again, begin again To feel, finally for real.
