The single, yet powerful line of "It's morbin time" demonstrates the both physical and mental transformation the character of Doctor Micheal Morbius has experienced, breaking free of the internal conflict he suffered throughout the movie. He realises this is the moment in his life where he becomes one with the Morbius, no longer hiding his true nature from the world but instead embraces it. The response of "Oh shit!" represents the shock of the viewer, in which they now understand that they too can embrace their inner morbius, and that the future of the space time continuum and sustainability of the human race depends on it. Truly poetic cinema.
