A/N: I'm so sorry at how long this has taken! Life has gotten the best of me, but I was finally able to find time to finish it! Enjoy!

The sound of wooden swords clacking against each other filled the arena as Thor and Sif dueled against each other. Despite already having sparring practice with the rest of The Warriors' Three, the two of them decided to get a little more practice in.

They danced around the arena, and each strike one made was easily blocked and deflected by the other.

"Your foot work and blade handling is as strong and graceful as your singing voice," Thor said with a smile.

The sound of a metal blade ringing as it was pulled from its sheath filled the air. Suddenly, Thor found himself pinned up against the wall with the cold blade of a dagger pressed to his throat. Thor made eye contact with Sif, who had abandoned her sparring sword on the ground a few lengths away, and was now holding the dagger she kept in her boot at all times to his throat. Her eyes were like fire, and her lips were curled into a snarl.

"What did you just say?!" she growled.

It wasn't until then did Thor realize what he had let slip. He thought for sure his comment was merely in his head. Clearly, he was wrong. "I, uh – I…"

Sif lowered her blade and took a step back. "It was you… it was you that night outside my door. What were you doing there?"

Thor lowered his gaze towards the dirt in front of him. "I had heard your voice when I was wandering the palace late at night, and I wanted to find how the voice belonged to."

"So you were eavesdropping?"

"In a matter of speaking… Sif –"

She shook her head. "How could you?"

"Sif, I had no intention of invading your privacy like that, and for that I apologize. But you voice is of a siren that cannot be ignored. Hearing you sing helped me sleep on restless nights."

"Nights," Sif echoed, her face not revealing any emotion, "you heard me more than once."

Thor nodded. "One other time, yes."

Sif took another step back. She remained silent as she appeared to ponder over something. "If you'll excuse me…" Sif trailed before turning on her heel and exiting the practice arena, leaving Thor to question what he did.

OoOoO

The stars had been out for a few hours by the time Thor made his way to his chambers. Before he had taken two steps towards his bed, he eyed a piece of parchment on the floor by his feet. Thor raised an eyebrow as he bent over and picked it up. He unfolded it and read what was written on it:

Please come to my chambers as soon as you can.

There was no doubt in Thor's mind that Sif had written the note – he'd recognize her handwriting anywhere. Thor turned on his heel and made his way towards Sif's. After each step he took, his heart beat against his ribs harder and harder, as if it was trying to set itself free of the confines of his chest. Once he reached her room, he rasped his knuckles lightly on the wooden door.

It wasn't long before the door opened before him. Sif stood behind the door, her hair now falling about her shoulders, and she was clothed in golden robes.

The two stood in silence for a moment before Thor raised the parchment and said, "I received your note."

Sif nodded as she stepped aside, allowing Thor to come in. Once inside, she closed the door and sat down on her bed. "Please, sit," she said as she patted the area next to her. Thor hesitated for a moment, and then sat beside her.

She let out a sigh and closed her eyes. "I wanted to apologize to you for my actions earlier. I should not have overreacted the way I did."

"I wouldn't say you overreacted," Thor replied.

Sif raised an eyebrow. "I held my dagger to your throat."

"A kneejerk reaction upon hearing something rather unexpected," Thor shrugged.

Sif shot him a side eyed glare. "It still wasn't appropriate. The only reason I reacted the way I did was because not many people know I sing. And I want to keep it that way."

"If I may ask, how many people know?"

"One."

"Excluding me?"

"Including you…" Sif trailed.

Thor's eyes widened slightly as he broke eye contact. When he looked back up at her, he whispered, "I will not tell anyone of this. But please know, you have the most exquisite voice I've ever heard."

Sif blushed at Thor's words and tried to turn away so he wouldn't see. "Thank you…"

"Would… would you sing for me tonight?"

She playfully rolled her eyes before she replied. "Go to your chambers, I'll be there in a few moments."

Thor smiled brightly as he stood up and made his way back to his room. It wasn't long after he entered that Sif arrived. Thor sat down on his bed while Sif pulled up one of his comfortable chairs.

"Is there anything you'd like to hear?" she asked.

Thor lay down on his side and looked into her eyes. "Whatever you know."

With a small smile, a delicate tune came from her lips.

Onda blu, dove vai

Non lo chiedero

Cio che tu perderai

Non lo cerchero

Cerchi di sfociare

Corri sempre giu

Quando trov il mare

Fiume non c'è piu

Wave of blue, long ago

Nothing but a stream

Rushing through mountain dew

To the sea's cold gleam

Nothing but a stream

Towards the ocean dream

Nata dal cielo

Day by day, deeper now

Al di là per quel

Songo sempre piu

As she continued to sing, Thor felt his eyelids growing heavy, and despite doing everything he could, he couldn't keep them open.

Al di là delle colline

Scorri oltre il confine

Fiume non c'è piu

Rolling wave, calling now

Voices clear and pure

Find the way home somehow

Find the way for sure

Quando vuoi sboccare

Scorri sempre giu

Finché trov il mare

Finché non sei piu

Wave of green, wave of blue

Flowing home

Non sei piu

When she finished, Sif eyed Thor sleeping soundly on the edge of his bed. She rose from her spot and placed a gentle kiss on his forehead. "Goodnight, my love," she whispered before she left.
