Back at the factory, the guys are trying to figure out what the heck is going on. They're not sure where the keyhole is, but they'll find it in the middle of the plant. They don't have the power to open the door, so they're just going to use an external battery to power the main generator. The guys are psyched to find the keyhole, and they thank the guys who opened the door for saving their lives. They can't believe that they are still alive. They thank the nurses and doctors who operated on them, and thank the guy who gave them the key to the key. The guy says that now that the "image of ruin" has been proven, the key has been "solved" to the final "digit" . This means that humankind has reached the end of its natural evolution and is ready to die. This is the "final destination" of biological evolution, according to the theory of evolution, which says that the final goal of evolution is "extinction." The guy is psyched to hear that he's going to be told that he was the "evangelist" , but he doesn't know who he was.
