Tara Duncan S01 E16 Summer School

Tara is at odds with her own grandmother, Isabella, who wants to send her to an advanced spell-casting camp on OtherWorld! Anteos, a "strange" harpy, chooses this precise moment to show up on Earth, putting Master Chem in a very awkward position. Called in by Tara to stand up for her, he finds himself forced to battle Isabella, who has challenged him to a duel.
