A maternity ward is the worst possible place for Mary to be on a full moon. When an emergency C-section is ordered and the cops show up, there’s no other option for Mary, Gary and their imminent baby or wolf but to run.
At the eight-month mark, Gary has the birth plan mapped out and all the couple needs is zero stress until after the full moon. When the cops call asking questions about a double homicide, Mary’s water breaks.
The wolf didn’t attack Emma and Gary while they were in the car in the outback and doesn’t recognize them during a rampage through the house. When Gary meets a normal woman, the mother of Emma’s new best friend, Mary gives him an easy out.
