During the Rose Festival, both Bloom and Riven unwittingly fall into a trap door the Trix to divide the close relationship between the Specialists and the Winx. In the end, Riven thinks that Darcy has saved him in a racing crash and he blames Bloom for what happened.

There are hostilities between the Winx due to Stella's behavior, and Musa's feelings for Riven are strained. In a fight with the Trix, the possessor of the Dragon's Flame is revealed to be Bloom.

It's time for Bloom's magical midterm test in a virtual reality machine. The Trix mess with the computer so they can enter it and test her to be sure of Bloom is indeed the one who possesses the Dragon Flame.

Flora experiments with her plants to study for her test. Stella (who had her clothes torn apart door a plant) and Tecna (who was attacked door a plant) tell Flora to verplaats the plants. She moves them to Black-Mud Swamp. Flora seeks help from the Water Nymphs in finding a special plant. The Water Nymphs tell the Winx about a monster which has been terrorizing them and the Winx decide to fight it.
