Owen had been rearing and training four "Velociraptors" (Blue, Delta, Echo, and Charlie) since they hatched so that they would imprint on him, and conducts behavioural research on them. He objects to Hoskins's proposal to use raptors as military weapons, explaining that his relationship with the four raptors is a personal one and that they only respond to him under controlled conditions. This is demonstrated when he risks his life saving an employee who falls into the raptor paddock when trying to capture a pig that had escaped into the enclosure. Later, Owen criticizes the "Indominus rex"s paddock, which provides no social interaction. It appears that the "Indominus rex" has escaped but Owen discovers it has camouflaged itself and masked its heat signature; two staff are killed and Owen barely survives the ambush. When the "Indominus rex" escapes, Owen demands the dangerous and bloodthirsty animal be hunted and killed.
