It has been a week since I've returned to Alfea, and I couldn't stop thinking about the prophecy. Who is the traitor? What does it mean by a beloved dove will perish? And, who will make a promise that they won't be able to keep?

"Hey, Aqua..." Roxy says softly, which captures my attention. "Is everything okay...?" I look over my shoulder at her, as she scrunches her brow in concern. I run a hand through my hair, wondering if she's the one that'll betray us.

I lower my head in dismay. "I just need some space."

She nods in response, before leaving the room. My hair covers my eyes, as tears form in my eyes. If I knew who would betray us, then it would help me prepare for it better. Suddenly, the ground begins to shake. My eyes flash dangerously, as I hurry out of my bedroom and onto the balcony. A bunch of orbs hit the barrier of Alfea, as I furrow my eyebrows in concentration. This has to be an attack from the Trixs and Cloud Tower!

"Aqua: Empressix!"

The orbs manage to break through the barrier, as I start to fly into the air. I hold out my arms and create a shield around Alfea, before closing my eyes in concentration. "Aqua, we have your back!" Bloom shouts from the courtyard, standing alongside Flora, Aisha, Musa, Stella, Rena, Roxy, and Daphne.

"Winx: Tiefix!"

The other girls immediately join me in the sky. "Winx, it's safe to assume that our attackers are invisible," states Rena. "Allow me to handle this." She raises her arms in the air, as the outline of the witches form in the air above us.

"Raging water!"

"Brilliant flame!"

"Nature's fury!"

"Sound wave!"

"I call on the element of wind!"

"Spiders' venom!"

"Sun beams!"

"Tidal wave!"

Our attacks hit the witches and knock them to the ground, as I exchange a grin with Stella. A second later, Tecna joins us in the air. "Girls, I did it!" She states, with a bright smile on her face. "I have the object that can turn Cloud Tower visible!"

She takes out the objects, as it lights up and turns the witches back to normal. A building immediately appears behind them, as my eyes widen in surprise. That's Cloud Tower! "Awesome job, Tecna!" I proclaim, nodding in her direction.

Seconds later, the Trixs fly out of Cloud Tower and head straight towards us. "Let's end this!" Icy declares. "Let's have the strongest fairy against the strongest witch! This battle will decide everything!"

I arch a brow. "Okay. You're on, Icy."

"Selina."

I lock eyes with Bloom for a split second, as an uneasy feeling forms in the pit of my stomach. Although they were once friends, I won't hesitate to destroy her. Even so, the nagging feeling of a traitor among us wouldn't stop echoing in my mind.
