Like I said, I had a similar premise, where new people are dropped on the planet and Isabelle tries to help them survive and she lost track fo Royce a long time ago. Then Royce comes out of nowhere, he's still kinda a jerk, he was using them to bait the Predators and Isabelle compares him to Noland which he is really offended by. They later discover there's a fourth Predator on the planet, hunting the Super Predators who has a score to settle with them. He's actually based on the Ghost Predator Neca created. So the characters form an alliance with Ghost, they help him kill the Super Predators, he'll take them home. But there's also a criminal in the group who is a real bad guy, and Isabelle doesn't think he should go back to Earth and they plot against him, but he's onto them and plots against them. Hence the title of my story, "Predators: Enemy of My Enemy."
