There's a decent one-episode plot in here, although the audience probably guess the identity of the villain at least one act before anyone else does. It's mostly an excuse to see the Charmed Ones use their wits and their emerging powers as they all contribute a role to the solution. Even their annoyingly preppy new Whitelighter Tessa turns out to have a way of helping out.
Meanwhile, despite several of the cast being missing in action, there's an awful lot of developments as plot elements seem to be revived and discarded almost at random. Galvin returns after what seems like an age only to find his quest was meaningless. Niko's memory loss hasn't been reversed but she moves closer to the truth about Mel. Maggie deals with discovering she has a new cultural heritage. And the Sarcana face the consequences of backing the wrong horse, although allowing Jada to survive smacks of a cop-out.
