Michael makes the basketball team thanks to his jock father's generous charity to Griffin's sport's department. Problem is, Michael wants nothing to do with sports and wants his father to butt out of his life. Gwen's growing attraction leads to a discovery that there is something magical about Michael: a force from another world, who will do anything to protect him.

A woman claiming to be Karen's long-lost sister shows up unexpectedly on Gwen's doorstep. Amanda and Gwen quickly hit it off, but Harve and Louise harbour growing suspicions about their mysterious guest. Also a practitioner of magic, Amanda offers Gwen a free-spirited and fun-loving alternative to Merlin's strict regimen. Faced with an opportunity to move in with Amanda, Gwen must make a difficult decision about her future. Meanwhile, Josh's increasing suspicions about Gwen and Michael's relationship lead him to set up a double-date: he and Gwen, along with Tasha and Michael. But his jealousy compels Gwen to reach an inevitable conclusion: she has to do the right thing and break up with Josh. Meanwhile, Tasha - who has learned the truth about Michael's lack of feelings for her - blames Gwen, and breaks off all contact.
