to x-ray the pupa prove futile, so it is decided to slice it open. In doing so, the doctors unleash a particularly feisty insect-like creature, but with Jim's help, they get it contained. Meanwhile, Fred is faring worse. In addition to having parasites from the insect, he has come down with a mysterious disease the creature was carrying. He goes into cardiac arrest, and when Judith Glass attempts to revive him with shock paddles, his chest violently explodes. Meanwhile, Marwella and the paramedic who brought Fred in come down with the same symptoms. Hospital director Roger Levering is resistant to quarantining the facility for fear of causing a panic, but Rachel is at least able to get him to bring in entomologist Elliot Jacobs in the hopes of identifying the mysterious insect. Before Elliot arrives, a group of children from the hospital's pediatric ward start roaming the halls. Lab technician Alice Bradley, tasked with guarding the insect specimen, is lured away from her post by her boyfriend, laser lab technician Ted Andrews, to have sex, which leaves the insect completely unguarded. The children wander on into the lab unnoticed. Seeing the insect, they decide to feed it some bluish powdery substance one of them finds in a bottle on a shelf. They argue over who gets to pour it into the jar with the insect, and as a result, they pour in an excessively large amount of the powder. Hearing the nurse and orderly returning, the children quickly leave. Unbeknownst to the two, the insect has grown to gigantic proportions and broken free of its glass prison. It promptly kills them both. Elliot Jacobs arrives, and he, Rachel, and Jim survey the carnage. Elliot is horrified when he discovers that the bluish powder the children fed the insect was a growth hormone. Now the insect is giant, and it could be anywhere. It turns out the insect is in the utility tunnels underneath the hospital, where the creature kills a hapless janitor and then begins building a nest for its brood. Rachel, Jim, and Elliot figure out how to stop the insect while Judith deals with the consequences of the disease the creature has spread throughout the building before the military, summoned by New York's Lincoln Institute (a facility for disease prevention), take drastic measures and destroy the facility.
