Plot summary
Bo is reluctant to comply with her role in a prophecy foretold by an order of Knights, until advice from a surprising source helps her make a difficult decision. The Morrigan reveals that Massimo is her human son, and when Kenzi tries to get even against him she is stopped by Vex, who was made Massimo's guardian after the Morrigan gave him to Vex when he was a little boy. Lauren, who had procured the Morrigan's DNA, created a serum with it and turned the Morrigan into a human.
