Vivian Krill was working in the control room of Jurassic World before and partway through the incident. She monitored the park along with Lowery and was on good terms with him. When Claire Dearing asked her why the West Plains were closed, Vivian told her that it was another Pachycephalosaurus that had broken loose and, when she expressed annoyance at the failure of the invisible fences for the second time that month, explained that the dinosaurs shorted out their implants when they butted heads. She was later talking to Lowery Cruthers when they were called by Claire, who demanded the current coordinates of the Indominus rex. Lowery, confused, obeyed and they were both stunned and horrified to see that it was still in it's paddock according to the implant and that there were people inside. Vivian frantically warned them to flee, but her warning came too late and she listened in horror as the Indominus killed and ate a worker and broke down the doors of the paddock. She attempted to alert the entire park about a dinosaur being on the loose, but was stopped by Simon Masrani, who believed the Asset Containment Unit could quietly contain its threat. Asset Containment proved ineffective and the majority of them were slaughtered by the creature. During Owen Grady's rant, Vivian exchanged a significant glance with Lowery before putting the park on alert. She later went with Masrani as he prepared to pilot his personal helicopter, fitted with a heavy machine gun, to deal with the creature, despite her worried protestations. Upon witnessing Masrani's death when his helicopter was attacked by Pteranodons, she reported the breach while crying in shock. After Vic Hoskins took control, she and the other personnel were evacuated, with the exception of Lowery who elected to stay behind. When he attempted to kiss her, she awkwardly told him that she had a boyfriend, but gave him a hug before departing.
