sedative to help the now-angry Mateo sleep. As he drifts off, he spies a shadowy form lurking in a dark corner. Seeing Laura out, Helena settles down to do some paperwork. Experiencing a chilling breeze, Helena looks up to find a figure in the shadows make its way to her from Mateo's ward. It steps into the light, revealing one side of its face and hand to be scarred and mutilated. Helena recoils in horror. Minutes later, Koenig arrives with a security team. A thorough search uncovers no sign of Helena's horrific intruder. Mateo, resting in a drugged sleep, is the only other person present. When she relates the details of her bizarre encounter, Koenig is hard-pressed to accept the conclusion that this was some sort of psychic experience.

Bergman reveals that during each incident, in addition to the drops in temperature, Alpha's instruments have detected Mateo's electrical-wave pattern. Bergman concludes the wave pattern represents a rare and powerful form of psychic energy. At a command conference, Koenig has trouble convincing the base staff that Alpha is being terrorized by a
