He explains to her that while she is a clone of Charlotte's, she is also her actual daughter because she gave birth to her. Maisie watches video footage of Charlotte (Elva Trill), and sees when she was pregnant with Maisie. Charlotte suffered from a genetic disease, but she managed to alter Maisie's DNA to remove all traces of the disease. Wu hopes that by studying Maisie's DNA, he can reverse the locust outbreak by altering their DNA.

Alan and Ellie sneak into the containment room for the locusts to get a DNA sample, just as Maisie tries to escape with Beta. Dodgson sounds the alarm, which causes the locusts to swarm around Alan and Ellie, but they manage to get out safely. They meet Maisie, who knows who they are. She joins them as they run. They are found by Ramsay, who agrees to help them because he finds BioSyn's work to be unethical. He sends them away in a monorail to safety. Ellie tells Maisie that she knew Charlotte as a student, and says she was a brilliant and kind person. Alan and Ellie arrive at the sanctuary and meet Ramsay Cole (Mamoudou Athie), BioSyn's Head of Communications. He introduces them to Dodgson, who promises they are working on something revolutionary and groundbreaking. Alan and Ellie are escorted to find Ian giving a lecture. Afterwards, he joins them and discreetly tells Ellie that the locusts are indeed part of a sinister scheme by BioSyn. Meanwhile, Dodgson meets with Dr. Henry Wu (BD Wong), who has since become remorseful of his actions in helping keep these experiments going, as he notes that the locusts have grown at an alarming rate. While the heroes work on an escape plan, BioSyn starts to burn to the ground, forcing the employees to flee. Dodgson attempts to make off with his work, and Ramsay tells him off one last time before leaving. Dodgson attempts to get away in the monorail, but is cornered by a trio of Dilophosaurus, who make a meal out of him. Beta comes upon the heroes and is sedated so they can safely bring her along. They are also found by Wu, who has found a way to alter the locusts' DNA to stop the spread. Just as the group prepares their leave, the Giganotosaurus reappears, but is then caught between the T-Rex and a Therizinosaurus. The humans flee to avoid the dino fight, and it ends when the T-Rex pushes the Giganotosaurus into the Therizinosaurus's claws.Not far from the cabin, Blue the raptor has asexually reproduced a child (who Maisie later names Beta). They go hunting together.
