The last episode of the fifth season ends with an obligatory high tension plot. Amita is kidnapped by a Manson type guy with a bunch of clingy submissive women. It all starts when he sacrifices two of them and then later another. They are all willing to create a heap of dead bodies. Of course, Charlie figures out a way to use an algorithm to find out where she is. The plot that this guy is using is rather hard to understand.
