Unbreakable Promises

Sidra didn't pack much and when the grandfather clock in the hallway chimed midnight, she knew it was time to leave. As her hand touched the doorknob, a rustling of air sounded behind her, like wind, but there were no windows open.

She turned slowly and her suitcase fell from her grip, hitting the floor with a soft thud.

Regulus stood in the centre of the room. She wasn't dreaming; her chest still ached too much for this to be a dream.

He steadied himself and then his eyes landed on her. He wasted no time in reaching for her and holding her to his chest, cradling her head. "Oh, thank Merlin." He breathed into her hair.

"What are you doing here?" She pushed away from him.

He seemed hurt but quickly hid it. "You were right, Sidra, about everything." He began to pace. "The Dark Lord... his methods are wrong."

"Regulus, what are you talking about?" She felt for her wand and sighed in relief when she touched the wooden stick in her pocket. She wasn't entirely sure she trusted anyone at the moment and it was better to be prepared.

"He took Kreacher." Regulus finally stilled and looked at her, his eyes wide with panic. "He barely survived. My house elf almost died!" He groaned in frustration.

Sidra looked around, worried he would wake her parents. She clicked her fingers, placing a silencing spell over the room.

"I thought we would be exempt, Sidra. I thought if we were loyal to him we would be treated better but he doesn't care, he'll kill anyone."

She placed her hand on his shoulder. "What happened?"

"The Dark Lord asked me for a favour. I should have said no but... Obviously, I would be dead right now if I had denied him. I lent him Kreacher and they left for hours. When my house elf finally did return, he was half dead, dehydrated and shaking. Sidra, you don't understand how scared I was." He grabbed onto her arms. "I thought I was going to lose him."

She caressed his face, recalling how dearly he cared for the elf, evident in how he treated him.

"Is he alive?" She asked.

"Yes, I managed to save him. But it opened my eyes. I am so sorry, my love." He stared into her eyes. "I was deceived by the Dark Lord and my family, I should have been on your side." He pulled her into another hug. "I'll never leave you again."

It took a moment, but she finally collapsed into his arms, breathing in his sweet scent and allowing tears to pool in her eyes at the joy of holding him again.

"I thought I was going to lose him." He repeated. "And I'd just lost you. I wouldn't have handled it."

She pulled back slightly and stared into his deep brown eyes. "You will never lose me, Regulus. I love you."

He kissed her fiercely, pulling her against him leaving no room for anything in between. "I missed you," he mumbled against her lips, sitting on her bed and pulling her onto his lap.

She studied his face, tracing her finger across his lower lip. She spent the last few days crying until exhaustion dictated she had no energy left to cry. She hadn't known how she was going to continue living without him by her side and now here he was, back in her arms. She would never let him go again.

"Then prove it." She whispered, reconnecting their lips.

They kissed slowly, as if time didn't exist.

Their clothes disappeared piece by piece, strewn across the floor.

Sidra moaned as Regulus kissed his way down her body.

"You're perfect." He breathed, pulling away to look at her. He lifted her left wrist to his lips and kissed the dark mark, never breaking eye contact.

For the first time, she didn't feel dirty having that mark embedded into her skin.

"Take me, Regulus. Please." She pulled him closer and he obliged, sliding into her with a moan.

The pain she felt as he thrusted into her slowly morphed into pleasure and soon her nails were leaving bloody marks down his back until they finished together.

The pair lay panting, entwined by every limb and combined with every shared breath. He moved a hair out of her eyes. "I love you, Sidra Finch."

She smiled, stars in her eyes as she looked at him. "I love you," She kissed him once more, tugging him closer. "I never..." She spoke against his mouth. "Want to be without you again."

"Maybe we don't have to."

She stared at him questioningly.

"Do you remember that book I took from Dumbledore's office?" She nodded. "And that part about binding spells?"

"Where are you going with this?" She propped herself up onto her elbow and looked down at him.

"The Unbreakable Vow, Sidra." He sat and grabbed her hands in his. "I'm scared... One of us is going to die. I couldn't live without you. If you don't feel the same–"

"Let's do it." She breathed. "Let's make an Unbreakable Vow because if you die I might as well cease to exist."

He reached for his wand. They entwined their left arms, dark marks brushing against each other. A silver cord wrapped around their forearms, binding them.

Sidra met his eyes as he spoke the words that bound them, saying that if one of them should meet an ill fate, the other would die at that moment too. She repeated his words and the cord shone brightly before vanishing.

It was done. They broke apart, now tethered by more than love.
