(TV: Liberation) However, Alistair Gryffen erased his criminal file. (TV: The Korven)
After the Time Blank experiment wasn't entirely successful, the Department imprisoned Taphony in a detention facility to keep it from being revealed. Gryffen hacked into virtual reality and unlocked her cell. She was met by two CCPC guards but she turned them to dust. Gryffen then transported her via the Space-Time Manipulator.

Thorne fabricated evidence via virtual reality to Darius Pike to gain K9's regeneration unit. When they put on VR goggles, Thorne showed him what was apparently his father suffering mental agony in a detention facility, as his cell was "nothing but white", with no detail to "draw the eye or distract the mind". June Turner said Darius' father was safely in a minimum security environment. (TV: Hound of the Korven)
