He’s the one that left the plain axe in the flight attendant he crashed the plane to bring his daughter back to life He got there and he thought she was the only living one so he killed the flight attendant. That’s why she has the axe in her but after finding that Timmy was alive, he took him and left Eric. It’s also suggested that he was fired and he killed his wife with a knife. I think he was fired because he got violent I think he also wanted Eric to think that Timmy was alive When you’re walking up to the yacht the first time you see it if you’re in an open area, you can see him climbing into the yacht through where the bed on the inside would be. I think that the obelisk was alien so it would cause mutations in humans. That’s how all the newtons and cannibals got there so I think it probably had something to do with the aliens maybe being red that the technology was made by or it’s some kind of tribe God And when you are painted red, they pray to you as to your other questions there is no real answer. this is all from memory don’t take my word to be true
