Nevertheless, Mulder and Scully visit the care home where Roland lives. When they gently ask him about the night of the murder, he tells them he had not seen anything out of the ordinary. He also inadvertently reveals his mathematical prowess by rapidly counting the star designs visible on Scully's blouse; however, his handwriting does not match the fourth sample taken from the whiteboard. The discussion ends when Roland experiences a violent vision involving Keats' head being frozen and has what seems to be a fit. Later that night, Roland has another vision in which he sees someone killing Keats. He appears at the lab and murders Keats by submerging his head in a tank of liquid nitrogen, fulfilling the vision. Keats' frozen body is left to shatter as Roland begins typing at one of the computers.
