Then, a few fairies from the college greet the Winx, and Stella gave them her autograph, as she likes being famous. While Flora is looking for her sister and about to surprise her when she finds her, the Winx go to the battle arena to watch the Specialists' training by riding a leaf-shaped ship.

In the meantime, Flora who was searching for Miele found her around her college and surprises her. Miele was so happy to see Flora and Flora is so surprised to see her little sister has grown up. Then, Flora and Miele chat for a while about Miele's college life. At Alfea, Roxy returns to Miss Faragonda's office as she managed to make the crow talk to her by using vocalization spells. The crow explains everything to Miss Faragonda about what happened. Faragonda and Roxy finally find out that the Trix have returned and the crow is actually Griffin.While Flora is talking with Miele, they see Cloud Tower floating in the sky of Lynphea. Flora is shocked and about to warn the Winx and the others. Meanwhile at Cloud Tower, the Trix asks Selina whether there are any good legendary creatures to be summoned at Linphea. Selina then summons the Treants to attack by waking them up.
Flora orders the Specialists to stop because something was not right. The Treants wake up and attack Lynphea College.

When they attacked the shield defending Selina, who is protected by the Legendarium, they lose their powers except for Bloom.
The Specialists give the Winx a ride back to Alfea where Faragonda and Daphne are waiting for them. The Winx explains what happened while Bloom is still curious of why she did not lose her powers. Faragonda tells her the reason that her power is made up of an inextinguishable Dragon's Flame and is the source of the Magic Dimension. Bloom then shares her Dragon's Flame power to each of her friends. Faragonda then tells the Winx to keep the share of the Dragon's Flame safe, as it will bloom into a new fairy power/transformation.
