This anomaly was not the real Mina Gryffen as she had perished long ago but a negative like that of a photograph. She was created as a result of Professor Gryffen's constant attempts to rescue his wife and children with The Spacetime Manipulator impacting on the continuum, warping reality into their shapes. These ghostly apparitions invaded the mansion and tormented K9 and the youngsters as they were Gryffen's new family and they needed to be disposed of for the ghosts to move in. Luckily they were banished back into The Void where they were trapped forever more (TV: The Fall of the House of Gryffen)
