Note: Okay, this chapter doesn't seem that important – but you'll see that later, it is. And please, please, please review!

6. Sing

The next morning, they were back in the memories. The scene was slowly shaping before them, the voice becoming audible, the movements no longer blurred. It was yet again, a similar room to the one where the events had last played out, but six years later.

"Why can't I see you normally?" asked Orion, curling up to his older brother as he spoke, looking at the ceiling.

"Sentinel thinks I'll hurt you," Megatronus said, and it was sad to realise that his chestplates still bore the scars from his first abuse with his father. "He thinks I'm what everyone calls a Decepticon," he shuddered, "because my optics are red."

"That's silly," Orion said, innocently and confidently, and it pained Optimus now, to see how unknowing he had been. "You wouldn't hurt me. And what's a Decepti… thingy?"

His brother looked sadly at him. "There once was a war. The Autobots – us – fought against the Decepticons. The Decepticons are twisted, sick and evil bots. They cause pain for their own pleasure, and they are cruel, ruthless and manipulative beyond comparison." He wanted to add 'but Sentinel is no better than them', but he refrained himself, for Orion's sake. It was a shock to hear that the young Megatron spoke of himself as an Autobot, and that he had spoken of the Decepticons – his would-be servants – in such a disgusted way, when he would become one of them, and sink to as low as they had fallen.

"But you're not a… a Decepti… Decepticon," Orion said, struggling to pronounce the word. "You're my brother, and I love you so much. Look at our brother-bond," he continued, looking down to where his spark would usually be, but behind and protected in the sparkchamber.

"I love you too," Megatronus said with affection, but he looked strangely worried. "Orion, don't say that in front of Sentinel. He'll know that I've been talking to you, and I'll get in trouble." He winced. Despite his youth – he couldn't be more than seven Earth years – the pain, suffering and hurt in his optics were there.

Orion tilted his helm to look at him. "Why do you call him by his name, and not 'father'?"

Megatronus stiffened, servos clenched, and digits curling into a fist. "He doesn't want me as his son. To me, he is not my father."

His brother looked a little concerned, but he didn't question his view. "Okay," he said, snuggling up to Megatronus's chestplates. "I won't say anything. I don't want to get you into trouble," but the tone of his voice suggested that he did not know what the trouble would mean. His brother smiled at him. "I'm tired," the red and blue mechling said suddenly, "Can you sing that lullaby again?"

Megatronus nodded, cuddling his brother. "Okay," he said, "It's time to recharge."

The older mechling started to hum a haunting melody that could hardly be called a lullaby, but it was certainly emotional, all his thoughts poured into it. It was filled with hurt, sorrow and regret, but sounded hopeful, anticipating the future in the pitch. It was beautiful in the notes, the way it sometimes sped up and slowed down, the wistful feel of the melody, sometimes sad, and sometimes happy, and the way it made you feel for the music. Orion was already in recharge by the time the melody drew to a close, in a peaceful, prolonged note.

Optimus admitted that he would hear the song, playing in his processor, even now, after all these years, before recharging. In a way, it told of his life, and his relationship with the brother he thought he knew. The truth was that he missed his brother more than anything in his old life, before he became Optimus Prime, and the song reminded him of what they had once shared. This was their song, and he could never forget it.

Gently, Megatronus laid Orion's helm onto the berth before leaving the room, leaving the house, slipping away unnoticed, which had always been a skill of his. He hoped that he had managed to escape his father's wrath for at least one day, and that his time spent with his younger brother would not be discovered. As he turned the corner, he smiled with satisfaction, the haunting melody playing in his mind. Sing.

Note: I will try to update the next chapter as soon as I possibly can, but I desperately need reviews and for people to comment on my work, like how they like the story so far, and ask any questions about the story so far. So please review! Also, from the next chapter, the story begins to get a bit darker, as the two young mechlings finally meet the Decepticons face to face. And yes, Soundwave will appear in a later chapter, and from there, he will be quite an important character. XD
