A pinch of Fairy Dust will do it!
While the Winx battle the Great Lizard Spirit, Bloom fights Acheron and the Trix in the Legendarium World. The Winx need all the help they can get - even Selina's - to fight dark magic and restore order in the magic dimension.
Thanks to the defeat of Acheron, Selina manages to get her powers back. It will be up to her to lock the Legendarium once and for all.
In the real world, the Winx (except Bloom) trying to hold the Great Lizard Spirit. Suddenly, magic returns back from Legendarium, which means that Bloom successfully defeated Acheron. The Winx realize, that Bloom is stuck with the Trix.
In the meantime, inside the Legendarium, Bloom is fighting with the Trix but gets disarmed, knocked down then trapped in the Cage of Sorrow that drains her powers.
At the same time in the real world, Selina got a plan on how to defeat the Lizard. While the Winx keep him busy, she gets into Cloud Tower and destroys the dragon skeleton in which the Trix held the magic, that they stole from the magic schools, thus returning the magic to their owners and destroying the Great Lizard Spirit.
At the Legendarium, Bloom reminisces about her friends and her family, which allows her to concentrate her powers to get out off the Cage and defeat the Trix. Finally, she picks up her wand and gets out of the Legendarium.

After that, Selina returns the book to its owner - Eldora and asks her to be her student once again. Eldora happily agrees.

“We'll wake up, and we'll beat you!”
“We'll have lunch, and we'll beat you.”
“And for dinner, we'll beat you.”
