Back at the lab, Laura discovers Dennis was not infected because he is a carrier of sickle-cell disease, as the species lacks immunity to human genetic diseases. While they plan to weaponize this weakness, Eve breaks out of her confinement to find Patrick. Press, Laura and Dennis pursue her, with Burgess and the military following. At the shed, they kill Patrick's offspring while Eve and Patrick transform into their alien forms and begin to mate. The mating stops when Press and Dennis intervene, allowing Eve to break free; Patrick, transformed into another alien form, overpowers Eve by forcing his tongue-tentacle down her throat, seemingly attacks her. Once Eve passes out Press impales him in the back with a pitchfork coated in Dennis' blood, causing Patrick to disintegrate and die.
