Medea introduces the daughter of Pelias to a Stew Recipe and Pelias gets his comeuppance for something or another. Aeson and his family dies... Sometimes. Acastus gets the throne of Ioclus and kicks our couple the hell out of his country. As a bonus we get to hear a bit of Medea Awesomeness that is pretty obscure.
Reasons we are explict: Murder, Cooking, Deception (at that level it counts as something to be warned about), Uniquness, Options.
