"Sister Act" Whoopi Goldberg is the special guest star in this episode and she plays the villain. She's an aged woman whose husband died years before from Multiple Sclerosis; she was unable to have kids on her own, so she applied to get them as a foster parent. Then she started a multiracial family where she was able to brainwash all the male foster children in order to make them doing everything she wanted (robbery, murder and so on). Even a tough guy such Logan is overwhelmed by her during the interrogation. Can the criminal justice system stop her? Hardly.
Logan suffers from post-traumatic stress disorder after shooting an uncover police officer. Dr. Olivet is back in helping him dealing with the issue.
