I sat on the roof of the lab to look at the stars as my two older siblings helped Thomas with my newly retrieved brothers. I hummed an old song, leaning back to look at the way I came to earth from.

"So far away." I sighed

I glanced to the side, feeling someone land next to me. I recognized him as one of Thomas' first creations. He froze once he met my gaze and I gestured him over. He hesitated, but walked over and sat down. I pulled him in a hug.

"I do not need your story, but perhaps you need something." I whispered

He started shaking in my arms, slowly letting himself lower.

"Do not hesitate so much, brother, everyone needs to cry once in a while. Robots and humans alike."

He lowered next to me, hugging my waist as I soon felt him cry in my clothed neck. I tightened my grip, rubbing his back in a soothing way.

"I will not force you back."I reassured

"I wanted to, I really did! But now he replaced me!" He cried

I frowned.

"Thomas would never, Blues. He still hopes to see you again, he told me himself. Why do you think your teleporter still works?" I whispered

He froze and slowly pulled away to look at me.

"I never lie, I never did. Perhaps it makes me different from other robots, doesn't it?"

He nodded and fully sat next to me, leaning his head on my shoulder. I wrapped an arm around him.

"Taking your time is essential, but knowing the truth is more. Do not assume, until you've seen."

My body slightly clicked, and Thomas' voice came through the speaker that was on the arm around him. He slightly jumped, but listened.

"Thomas, is something wrong?"

"A-Ah, Star. Nothing is."

"We both know you cannot lie to me, Thomas. I will not force you, but lying is a bad habit."

Blues slightly laughed at that.

He sighed.

"I had another child, before Rock and Roll. Sadly, he...ran away. His power core was defective, and...I hoped he would come home to let me fix it, but it's probably too late."

A small silence followed.

"If I were to find him, I will help him."

The recording stopped on Thomas' fond chuckle and I looked back at Blues. Tears were flowing once again, his hand gripping onto my wrist tightly.

"How was I so blind...?"

He clutched his chest and I put my unoccupied hand on his.

"W-Wait."

"Unlike Thomas, I can do it easily, in the click of a finger. It won't hurt, it won't change you, it will simply change your battery to whichever you'd like."

He paused.

"Solar...?"

"As you wish." I hummed

My hand glowed yellow and his eyes widened. Once I was done, I pulled away and looked at him. He patted his chest and looked at me with a bright smile. He launched himself in my arms and I hugged back with a smile.

"Star..?"

I hummed.

"Will you accompany me back to my father?"

"Of course, brother." I answered

We stood up and jumped down onto the ground. We walked up to the door and I looked back at my brother. He seemed nervous. I grabbed his hand reassuringly and pushed the door open. Thomas looked up at the noise and he dropped his tool once he saw me and Blues. He ran up to us and engulfed his son in a tight hug. He was crying already, apologizing over and over. In return, Blues hugged just as tight, tears flowing once again. I smiled, hugging Rock and Roll to my sides as they gripped onto me in their confusion.

After a few explanations, and a verification on Blues' core, we could finally start to rest.

The next day, as I was finally filling the true purpose of my body, I was humming, my voice bouncing off the walls of the empty cave. It was soon, that footsteps seemed to mix with my song. I leaned back, hanging upside down to peer at my visitor. I stopped my song, holding my arms along my sides as my pickaxe changed to my laser cutter. A robot master, unfamiliar, stepped into view, and the lights of my armour snapped off in a single second, enough to let me merge with the darkness. He looked around, mumbling under his breath, about me probably. I slowly crawled lower on the wall, to take a better look at the robot. He was...blocky, made of a lighter material than metal on the outside judging by the vibrations' bouncing off of him. I could see round eyes glowing in the darkness, unlike mine. His eyes were a glowy sapphire blue and I could see a little hint of green on his eyelids. I soon reached the ground and crawled around him at a long distance. I think he could feel my eyes on him as I felt a faint shiver run down his body. He started frantically looking around. I started crawling up the wall again and once I was high enough, I let my lights glow. He froze.

"Who. are. you?" I asked quite rudely

I would have not greeted him that way, if it weren't for the bad intentions I could feel emitting from his coding. He didn't answer and seemed to get out of his stupor. Leaves flew around him.

"Master asked for you to be brought to him." He simply said

The leaves lunged at me and I growled, running along the metal beams that supported the place. He seemed perturbed ever so slightly by my position. I could still barely see him, but my vibration based scanner allowed me to dodge the bullets he sent.

"Stay still, don't make this any harder than it already is." He pleaded

I let go of my magnetism, falling, twirling midair and landing a few meters in front of him. I pulled out my two price jack cables and they connected to my forearm speakers.

"I was built to survive the dangers of mining caves, I can explode and pierce the hardest of diamonds. What makes you confident you are not the one being hunted, robot master?"
