In the depths of Andros, Aisha must be able to save Nex, who is in grave danger. Meanwhile, the other Winx try to prevent Obscurum and the Staryummies from taking away the light of Gorgol, but unfortunately they are imprisoned inside the star and attacked by some magical anemones. Aisha understands how to calm the anemones and the Winx manage to give light back to the core of Gorgol.
At Valtor's Palace, Valtor reprimands Obscurum for his failure to defeat the Winx, and sends him to another dimension as a form of torture. After the punishment, he tells Obscurum of his next plan to attack Hypsos, using the Hydra constellation as a tool. Though Obscurum his confused at first, and has concerns about the Winx getting involved once again, Valtor reassures him that all will become clear to both parties.
