Hard Rain

In her first week at Griffin Secondary, Gwen realises there's something fishy about Ms. Blatt, the Socials teacher. Tasha suspects that Ms. Blatt is a witch, working a spell to steal youth and beauty from her students. Intuiting that Gwen has a sensitivity to magic, Tasha tries to enlist her to defeat the ever more youthful teacher - but meets with resistance and denial from Gwen. Meanwhile, Gwen meets Josh - and has her first encounter with Merlin.
