The first thing that Gemstar realised when she opened her optics, was that there was no pain, this, she decided, was a good thing. She then realised it was dark, most likely night time, she saw Ratchet sitting with his optics closed on a huge seat, his head lolling to the side, and every now and then it would snap up and begin lolling over to the side once more.

"you wake at last child" a cruel rasping voice muttered and Gemstar's optics widened, her head snapped to the side and she saw Jack, strapped tightly to a metal berth, he was grinning, and when he spoke, his voice was quiet, and a much more powerful voice spoke over his at the same time.

"your poor little human friend tried to save you, now look what has become of him" Megatrons voice taunted her and she stared, dumbstruck at him.

"your in…Jack…" she muttered and he laughed loudly, she heard Ratchet stand up and she sat up and watched Jack, rather, Megatron as Ratchet walked over to her.

"how?" she asked him her voice barely a whisper

"We don't know" Ratchet told her, pulling her into a comforting hug, but her eyes never moved from Jacks eyes, gleaming, bright, red.

Optimus was happy when he heard that Gemstar had woken up, but when he came in he felt less so, as he was reminded of Jack's current…condition, Mieko was sat hugging his sobbing mother whilst Arcee wouldn't even speak, she just couldn't, for fear her voice would betray her emotions. Gemstar was sitting, cross legged on her berth, optics closed, and Optimus presumed she was thinking, and he hadn't wanted to disturb her, so he busied himself, with anything he could. Bumblebee had only just recovered from his run in with Nightstar, so he was still confined to his berth, and Bulkhead was looking after Raff.

Ratchet stood beside Gemstar and watched her, she was muttering something.

"think like a decepticon…think like a decepticon…"

Ratchet stared open mouthed at her, think like a decepticon? Why would she do that? Was she trying to bring Nightstar back out again?

"think like Nightstar" she muttered and then stopped talking altogether, and for a second Ratchet thought she had done it, until her eyes snapped open, they were a brilliant…Purple…

Gemstar needed to think like Nightstar again, otherwise how would she save Jack? Nightstar would know what to do, even if she was her decepticon half.

"I knew it was only a matter of time"

Gemstar opened her eyes and she wasn't in the base anymore, she was standing face to face with herself, no, with Nightstar, her other half.

"matter of time before what?" Gemstar asked, they were standing in oblivion, they weren't anywhere, everything was dark, pitch black, there was no light, yet she could see Nightstar perfectly.

"before you came for help" Nightstar replied, the only real difference between the two was their eyes, Gemstar's were blue, Nightstar's were red.

"tell me how to save Jack, how to get rid of Megatron" Gemstar pleaded but Nightstar shook her head.

"It doesn't work like that, we are one entity, and you need to stop fighting who we are"

"I am not a decepticon"

"I never said you were, but you and I are the same person, but you continue to fight me, you need to accept me, we need to become one, like before…"Gemstar stared at her, she was scared, not of Nightstar, but of what she was saying, why was she scared, because she knew it was true.

"we have never been one" Gemstar replied indignantly

"when we were fighting Megatron, we were one, our thoughts the same, stop being foolish! And accept it!" Nightstar was yelling now, he decepticon anger evident.

"but, what would that make us? Not an autobot, not a decepticon, a…hybrid?"

"I…suppose…yes, but we are not alone, there must be others out there like us, Gemstar, we are one, don't fight it" Nightstar told her and held out her clawed hand, Gemstar hesitated, then took it.

Her eyes snapped open, and Ratchet stumbled backwards, she stood up and looked at the two pieces of dark energon, and it suddenly made sense.

"Gemstar?" Ratchet asked and she turned but shook her head

"Nightstar!" again the shake of her head.

"then who?"

"I am both Gemstar and Nightstar, we are one in mind and spark, I am Sunstar" she told him walking towards the dark energon and picking both halves up, one in each hand, before facing Megatron.

"One piece of energon, connected to two sparks, well down Megatron, I would never have thought of something so suicidal" Sunstar said to him, she suddenly had the attention of everyone in the base, Megatron included.

"what are you talking about Gem…Sunstar" Ratchet asked her and she smiled kindly

"This is one single piece of energon, yet it is connected to both myself, and Megatron, therefore, one cannot live without the other, and one cannot die, unless the other does, and technically, Megatron is dead, therefore, what I am about to do, should kill him, and set Jack free"

"and what are you about to do?" Arcee asked her, but they all knew the answer

"die"

Before anyone could react, she rammed both pieces of dark energon into her spark, and screamed in pure agony, Jacks body started to spasm, and a wisp of dark energy floated out through his mouth, and the same happened to Sunstar, before the dark energon shattered, and she fell limply to the floor, still, unmoving, and her spark extinguished.

Jack lay still, and his mother and the doctor rushed over to him, he was still, but alive, Jack was alive. Ratchet was busy hauling Sunstar onto a berth and trying desperately to ignite her spark again, but it wouldn't work, she was dead, Sunstar, Gemstar, Nightstar, she was dead.

Optimus fell to his knees, and sobbed, she was dead, he had only just found her, and already she had died, it was his worst nightmare come true, now he would never have his precious sparkling back, before he had hope, now, he had nothing.
