Furiously Jason chases Medea to kill her for wounding Ariadne probably mortally, but is called back by Hercules to her sickbed. Pythagoras brings in the Oracle, who finds the magical dagger's Colchis spell is beyond her powers to heal, nobody knows a cure except the three Grey Sisters (Phorcide Graeae). Jason rides out with Hercules and Pythagoras to question them in the Calabrian forest, finds them greedy for a gift he didn't bring but forces them by seizing their shared eye. The only cure is the poison monger's own blood, but they warn Jason his fate is inextricably linked to Medea's. Jason gets a vial of it but is captured by surprisingly conciliatory Pasiphae, rescued by Heracles and Pythagoras and in time to save Ariadne, who finally agrees to wed him.
