There are several patterns in Winx Club...did you notice them? I'm going to list them for you!
1. Every 2 seasons, there is a new Winx Club character (Season 2: Layla. Season 4: Roxy)
2. Every season, there is a new villain (Season 1: the Trix. Season 2: Darkar. Season 3: Valtor. Season 4: The Fairy Hunters)
3. Every season, there is a new transformation (Season 1: Winx. Season 2: Charmix. Season 3: Enchantix. Season 4: Believix, Sophiex and Lovix.)
5. The 'new character' (see #1) is always a princess (Layla: Princess of Andros, Roxy: Princess of Earth)
6. In Season 3 and 4, the first girl (in season 4, all of them) transforms into the new transformation in episode 6
7. Every 2 seasons someone dies (Season 2: Sky [Sky dies in Episode 10, but then Bloom brings him back to life]. Season 4: Nabu)
Has anyone noticed any other patterns?
