Is it in Stella´s solaria ring? Is it hidden at Alfea? Or somewhere else? As the witches try to find the Dragon Fire, they get into an epic battle with Bloom and rest of the Winx Club girls. As they´re about to destroy Musa, Bloom begins to glow with a strong and powerful light. Could it be? Is the Dragon Fire inside her?
