Yet The Leftovers does not concern itself overmuch with the enigma of the Sudden Departure. Lost became self-parodically enmeshed in a madly proliferating web of embedded mysteries that by the end seemed as if they were being invented simply to keep the intrigue going, and could never be satisfactorily resolved. The Leftovers offers no hint that its central mystery will ever be explained. If the first season is anything to go by, this absence of explanation is the point. The series is set three years after the Sudden Departure, and by now the event has become part of the assumed background of the characters’ lives: a vast epistemic void which they are simultaneously always ignoring and negotiating. The Sudden Departure is then like trauma as such: an unfathomable puncturing of meaning, a senseless spasm of sheer contingency.
