When Blake and Lynn find each other the first time inside Temple Gate, they try and get away together but Lynn stops multiple times due to stomach pain. Lynn asks Blake not to ask her about what the cult members did to her, leaving the player to the interpretation of some kind of forced sexual act. Documents and journals throughout the game can support this theory, but anyone with a 5th grade understanding of biology would know that wouldn't work that fast. Blake says to himself that it would be impossible for her to be pregnant as they "haven't in months." The next time that Blake see's Lynn is at the end of the game and she's full-term pregnant. As they weather through an apocalyptic storm, they find refuge in the chapel for Lynn to give birth. When Blake shows her the baby, Lynn says "There's nothing there," before passing away. The cults could have induced Lynn into an accelerated false pregnancy, or the microwave towers manifested the existence of the baby and pregnancy altogether.
