shuttle, but Lee makes him leave it behind due to the noise it would make if powered on. As they are getting ready to leave, Regan secretly gives him back the toy, but without its batteries. When they leave, Beau takes back the batteries without anyone noticing. While walking back home, Beau turns on the space shuttle, which starts making noise. Almost immediately, Beau is killed by a nearby creature. Almost a year after Beau's death, the family has seemingly gone back to normal, with Evelyn several months pregnant. Marcus reluctantly goes fishing with Lee while Regan, upset that she cannot go, visits Beau's grave. While everybody is gone, Evelyn goes into labor; while going downstairs, she steps on a nail and drops a photo frame, which alerts nearby creatures.

She hides behind the falling water to mask her sound as the creature moves toward her. After Marcus and Regan get into an argument, Marcus falls through the silo's roof, and Regan jumps in after him.

Lee finds Regan and Marcus, and tells them to get in his truck and use it to get back to the house. A
