Anything written on Wikipedia is to be taken with a grain of salt, but assuming the titles in the episode list are real, I’ve made some guesses about the next episodes.
14. “Animali nel Bisogno” (Animals in Need)
We already basically know what will happen in this episode because of the preview. The Winx become Gardenia’s superheroes, and Roxy tries to stop some animal hunters’ plans. It doesn’t sound like an eventful episode.
15. “Città di Mistero” (City of Mystery)
There isn’t much to read into this title. I think the Winx and Roxy (right, Rainbow) will probably learn something about the Fairies of the White Circle in this “mysterious town.”
16. “Dove è Roxy?” (Where is Roxy?)
Are the Winx falling asleep on the job? Just because she can defend herself now, it doesn’t mean they shouldn’t be watching her anymore. Perhaps something she learns in the previous episode makes her upset and she decides to go on a one-woman quest—like Bloom whenever she’d learn about her past.
17. “Incontri Il Nuovo, Trix!” (The New Encounter, Trix!)
Well, well, well. The evil three are back, are they? I bet everyone was starting to wonder why they were being so quiet. What’s a season without them? But this may be Trix v.4.0; they joined the Ancestral Witches at the end of Secret of the Lost Kingdom! Will the Winx be able to handle that combined power?
18. “Believix Potere Winx!” (Believix Power of Winx)
Again, very broad. One question, though: now that Roxy has her Believix, will she be included in this “power of Winx” business? Or will Rainbow separate her again?
19. “Una Storia di Amore” (A Love Story)
Ah, amore! Three possibilities: Roxy finds a guy, Musa and Riven get back together, or Stella and Brandon get engaged (there has been a rumor about their wedding). The first one’s a longshot. I’m leaning towards the third one mixed with second one.
20. “Il Segreto di Sky” (Sky’s Secret)
How many secrets can one prince—excuse me, king—have? Poor Bloom! She’s engaged to the most complicated guy in the universe! Then again, he was extremely busy with his Eraklyon duties at the beginning of the season, and we don’t know what they were. Could they have something to do with the wedding? Is there a conspiracy back home? Is Sky adopted? 😛
The last six episode spaces are marked as “unknown.” That brings the total to twenty-six, which may be a mistake. Doesn’t season four have twenty-four episodes? We’ll see if any of these titles stand.
What do you think about them?
