A/N:

Hey guys! Yeah… I got this idea while watching Hau Mulan (the real-people movie of Mulan, it's actually a really inspirational film!) and decided to write this. Oh and also I never really recognized that Regulus was actually two years younger than Sirius…I've always seen him as being older so in this fan fiction I have made him four years older than Sirius just cause I think it fits him better.

I glanced down at my younger brother, his hair was messy and in his eyes as usual and his pale grey eyes were wide with curiosity as he squeezed my hand tighter, peering into the forest before us.

"Reg?" he asked.

I returned my own icy blue gaze to my brother, hating the nickname he had given me but answered anyways. "Yes, Siri?"

"What's in there? Will it be cool?"

His questions puzzled me; I had expected him to ask whether it was scaryor if it would hurt him however his brave attitude stirred more words to penetrate my curbed tongue, "Are you scared?"

"Not really, I trust you Reg. You would never hurt me. Would you?"

I closed my mouth firmly and stared straight ahead; clearing my throat I let a small smile raise the edges of my lips "No."

Sirius smiled and looked at the forest again, a sweet grin now playing on his face. He took a step forward, his fingers still gently grasping my larger hand. He looked back at me his dark brows questioning me with such innocence that I had to look away "So, just to that big tree over there right?" he asked gesturing with his hand to a large oak tree with no low hanging branches, and bark so smooth that it rivaled even the surface of a calm icy pool in the middle of winter.

I nodded returning my eyes to my younger brother. "And don't forget you have to get the key. Or else we can't go see what's in the room" I reminded.

He laughed, "Don't worry. I've got this!" he exclaimed and raced forward, the sparse trees making it easy for me to track his movement, as he made his way towards the chosen tree.

I closed my eyes, my fists clenched tightly in two fists. Please. Please. Please, let him fail. Let him not reach the key. He MUST not get the key. I opened my eyes and watched as Sirius struggled to reach the key that was positioned, hanging from a nail in the bark just above the first branches that protruded from the smooth pale bark. "Please" I whispered. His dark hair fell into his eyes as he leapt up; his arms still at least two feet below the branches.

I could not help a smile spread across my face Yes. He could not reach it. My hopes had been verified. I was about to call him back when a pallid, eerie light shown around my seven year old brother. A sigh escaped my lips, my eyes fixed themselves on the small boy as his eyes watched, unblinking, as the silver key descended from the trees and into his open hands.

I almost let out a cry of anguish, but stopped myself just in time before his grinning face turned towards me. He raised a clenched fist high above his scruffy head.

"Look Reg! I got it! See? I got it!" His grin was so wide that I could have sworn that it covered his whole face. I would have smiled but grief lodged itself deep inside my heart as he ran back to my side.

You know what you must do Regulus. This is what fate has chosen for you. This is goodbye for a while but not forever…someday he will understand what it is you must do.

Before long the small boy was standing in front of me, his hair in his eyes again obscuring his joyous face. In his hand was the small silver key.

When he saw my placid face he tilted his head slightly and offered it to me hesitantly.

I did not take it. Instead I rested my hand lightly on his head. I opened my mouth trying to push the words from my throat. I wanted to be happy for him; he was a wizard like me, yet I knew the fate that now rested before the both of us, and I knew what I must become to protect him.

After what seemed like minutes but were only heartbeats, I spoke my voice slow wanting to savor these last few moments "Well done…Siri."

Siri…was this the last time I would say that? From now on he would have to be Sirius.

"Sirius" I said aloud testing the word on my tongue. It tasted weird, so formal so…alien. His grey eyes were still trained on me. "Yes Reg?" he asked still oblivious of what I was thinking.

I thought of leaving him now, letting this be the last moment we shared as true brothers…but the contemplation of doing so only worsened my trifling emotions. The corners of my lips tickled as they played into a slight smile, "Lets go open that room!"

His face brightened with relief as he raced ahead of me. I followed at a sower pace; my hands stuffed into my pockets.

Please. Please. Please, someday let him understand.
