The rain starts falling, and Tubal-cain becomes angry that he wasn't chosen to be rescued. The followers of Tubal-cain make a run for the Ark. In the meantime, Noah finds Ham in the forest and forces Ham to save himself and leave Na'el to die when she is caught in a metal trap set for an animal. All of Noah's family enter the Ark except Methuselah, who purposely remains behind in the forest, (after finally obtaining a berry that he had sought since Noah arrived), and is swept away by the rushing waters.
As the deluge begins, the Watchers hold off Tubal-cain and his followers as long as possible but in the end, sacrifice themselves to protect the Ark from the mob. Upon doing so, they ascend to Heaven after leaving their mortal stone form. As the flood drowns the remaining humans, an injured Tubal-cain climbs onto the Ark and solicits Ham, playing on anger toward Noah for allowing Na'el to die. Ila becomes pregnant as the rains stop, and begs the creator to let the unborn child live. However, Noah interprets the ending of rain to mean he must carry out the execution, and against his wife's dissuasions, resolves that if the child is a girl, he will kill her to satisfy the Creator's wish to destroy humanity.
