Tricorder analysis and attempts to use the transport to remove the parasite both have no effect on the creature. Under the alien's control, Telfer is able to walk through a force field, and is stunned by a phaser shot from Janeway, leading the creature to leave his body and attempt to enter the shuttle's computer systems instead, tapping with the environmental controls. Convinced that the creature is hostile, Harren disintegrated it with his phaser, leading to the appearance of numerous alien ships pursuing the shuttle. Telfer later revealed the only thing he could grasp from the alien's attempt to communicate was the phrase "do not belong", which could be interpreted in many ways. Fortunately for the shuttle crew, they were able to escape the pursuit and make it back to Voyager.
The origins of the alien creatures are never revealed. Although unconfirmed, Janeway has speculated that the creatures are made of some form of dark matter, but Harren remained skeptical of the idea, claiming that complex molecules of that nature would collapse under their own weight.
