While she has briefly crossed over into Bastian's world, to have him profess his love for her, the real world behind them is constantly moving. The wedding is going ahead and everyone expects Prudence to be there. Sensing there might be trouble, Michael sends his step-sister Millie to spy on Pru and find out what she's up to. Before long it is all out in the open - Pru's uncertainty about her commitment to Michael, Bastian's proposal, and the fantasy world she has been living in. She must now choose not only between her two suitors, but how she will spend the rest of her life. Whether that be fifty more years, or an eternity. less

The wedding is over and Michael is dead. Forced into the chambers of Bastian's palace, Prudence wants nothing more to be free of her new husband, as he has done the unforgivable. Together she and her friends must hatch a plan for her escape - one that will resurrect some old foes of Bastian - but who might actually do more harm than good.

This episode concludes the series. A year has passed since Prudence fled from Bastian's palace, but in all that time no one has seen her. She seems to have completely disappeared. Her friends Christine and Elliot enlist the help of wolf shifter Reese to uncover what happened to Prudence, while Bastian remains trapped in his world dealing with enemies from his past.
