The morning light filtered through the curtains, casting a soft glow over the cozy room. Cassandra, now Cassandra Scamander, stirred in her sleep. The weight of the past years settled heavily on her shoulders, but today was a new beginning. She and Theseus had finally tied the knot, and their little one, Dahlia, was the light of their lives.

Theseus was already up, cradling Dahlia in his arms as he hummed a gentle tune. Cassandra watched them from the bed, a smile playing on her lips. The sight of her husband and daughter filled her heart with warmth and contentment. Yet, a shadow lingered in the corners of her mind.

Gellert Grindelwald.

She had chosen Theseus, but Gellert's presence haunted her dreams. His voice, his touch, his promises of a new world—they all echoed in her mind like a relentless storm. She had tried to bury those memories, to forget the man who had once held her heart captive. But Gellert was not so easily forgotten.

"Cassie?" Theseus's voice broke through her thoughts. "Are you alright?"

She nodded, forcing a smile. "Just lost in thought."

He set Dahlia down in her crib and joined her on the bed, wrapping his arms around her. "I know it's been a lot, but we have each other now. We'll get through this together."

Cassandra leaned into his embrace, finding solace in his strength. "I know. I just... sometimes it feels like he's still here, watching, waiting."

Theseus tightened his hold on her. "He can't hurt you anymore. You're safe with me."

She closed her eyes, letting his words wash over her. She wanted to believe him, to trust that Gellert's grip on her mind would eventually fade. But every time she closed her eyes, she saw Gellert's face, heard his whispers.

Switch to Gellert's Perspective:

Gellert Grindelwald stood in the shadows, his piercing gaze fixed on the horizon. The world outside his confinement was moving on, but he remained trapped in the past, consumed by thoughts of Cassandra. He had once held her heart, and he was determined to reclaim it.

Every night, he reached out through the veil of dreams, whispering her name, reminding her of what they had shared. He could feel her struggle, her attempts to push him away, but he was relentless. He would not let her forget.

"Cassandra," he murmured, his voice a soft caress in the darkness. "You belong with me. You know it in your heart."

He envisioned her, standing by the window of their old home, the wind playing with her hair. The memory was bittersweet, a reminder of what he had lost and what he still yearned to regain.

Gellert had given Cassandra an enchanted necklace before they parted ways, a piece of his magic that allowed him to communicate with her. Every day, he used it to speak to her, to remind her of their bond. He whispered promises, plans, and confessions, trying to reignite the spark they once shared.

One evening, as he reached out through the necklace, he heard something different. The sound of a baby's cry—Dahlia's cry. A pang of jealousy and desperation surged through him. His voice trembled with newfound resolve as he whispered through the necklace, "I will not be forgotten, Cassandra. I will fight for you, for us."

He knew then that he had to act. He had to reclaim what was his, to fight for the love that had been stolen from him. Gellert's determination burned brighter with each passing day. He would not rest until Cassandra was back by his side, where she truly belonged.
