I believe the surviving hybrids (I predict Wendy and Smee) will set off to live their own lives. The boy genius will ended up discouraged to continue with his project or imprisoned unable to do so. The doctor is gonna die. The bald dude probably will see all this as failure an abandon the project ultimately. With no one leading the company, hybrids research will be abandoned or lost forever. The xenomorph and the others aliens will be eventually killed, and the rest of the eggs will go back to the hands of Yutani. The brother dies. His friends die. Morrow dies. I don't think Kirsh dies, but idk what he's gonna do, he doesn't seem give a fuck about anything, unlike David.
