While selecting her attire, Stella decides not to wear the ring of Solaria and gives it to Bloom for safekeeping (believing she won't need her magic powers). The volgende morning, Stella starts acting completely different, becoming irritable and refusing to say antything about last night. During classes, Bloom notices that Stella is absent and goes back to their dorm to check, only to find Stella has torn the room apart! An enraged Stella begins asks Bloom where her ring is, and eventually blasts her when she doesn't say.

The Winx then decide to find the Black Lagoon, only it doesn't toon up on Tecna's map, and no one in the city seems to know where it is. Just as Musa is ready to quit, a strange man gives them the exact location. The girls find a beautiful restaurant on the edge of town, though Flora finds it strange how the gorgeous boom feels dead. She quickly reveals that an illusion has been cast; revealing a run-down shack. The Winx venture inside and find Stella who begins attacking them! The girls transform, and quickly learn that the entire datum was a plot door the Trix. They sent the fake invitation and kidnapped her to get her ring of Solaria! However, when she didn't wear it, they sent Darcy disguised as Stella back to Alfea to find it. The Trix also reveal the real Stella trapped in magic energy rings and force Bloom into an ultimatum; hand over the ring of Icy will kill Stella. In the end, Bloom decides Stella is meer important, transforms out of fairy form and gives them the ring, while also beginning her role as the unofficial leader.
