Continuity mistake: In one shot we see the thick green blood dripping off of the autopsy table which Jason is on, and there is plenty of blood running down the side. In later shots when Adrienne turns around and looks at the table, the amount of blood dripping down the side of the table has decreased, and the amount changes in following shots as well.
Continuity mistake: At the beginning they show a close up of Jason, the skin around his eyes and ears (around the outside of the mask), are flesh colored and looks like normal healthy skin. When Adrianne takes his mask off during the autopsy they skin is grayish like it's decaying.
Continuity mistake: When Rowan is stabbed by Jason she slides down to the floor and freezes sitting up. She remained undiscovered and undisturbed for over 400 years until the scientists find them. So how did she end up lying on her back covered up by what look like exhaust tubes? Aside from the unlikelihood of no-one stumbling across her for all that time.
