Jack (Mercenary)

"Seriously, guys, I'm kind of exposed down here..."

- Jack

Jack was a mercenary employed by Eli Mills. He was part of the team sent to retrieve a bone from the Indominus rex's skeleton. Using the callsign "Land One," he was charged with opening the gate to the Mosasaurus lagoon so that the team's mini sub could enter it. While he was working, he was briefly startled by a Dilophosaurus.

He was attacked and chased by Isla Nublar's resident T. rex; due to the noise of the thunderstorm and the rotor blades of the nearby helicopter, he hadn't heard her approaching him, or the yells of his fellow mercenaries in the helicopter shouting at him to run. Upon finally seeing the T. rex, Jack ran for the chopper, which dropped a rescue ladder for him. Although he managed to grab it and escape from the carnivore, he was seized and eaten by the Mosasaurus as the helicopter flew over the lagoon, much to his friends' horror.
