Louis Asekoff (played by Tyler Thompson) was the son of Mrs. Asekoff and her husband Michael. While his father was teaching him to shoot, they stumbled upon the bloody remnants of two surveyors who had been attacked. Louis and his dog, Bo, fled on his father's orders, but stopped short when he heard his father shoot. Michael Asekoff went missing, but the fortunate arrival of Fox Mulder and Dana Scully proved very helpful in his rescue. Mulder suspected some sort of invisible creature was responsible, which proved to be correct. Louis narrowly escaped one of the creatures that had entered his house during the night.
