"I think it's coming online..."

Those words were the first she ever heard. And they were pronounced by a voice slightly concerned.
Awakening slowly from the darkness, she was little by little becoming self-aware. Taking in her surrounding, thanks to the sound around her.
She waited for her system to finally onlining.

Optic sensor checked

Finally! She crackled her optics open and took her first look to the mechs were present, but none of them were registered in her data-bank. She stared at them, taking in their look.
The closest one was fidgeting with a computer, and his dark paint job was shining. Not too far from him a gigantic grey one with a black cannon on his arm was looking at her. And next to the giant, another one, white, blue and red, also looking at her.
She wanted to turn to look around better, when a voice caught her attention:

"Megatron, I have good... and bad news..."

It was that voice, the first she ever heard... And it was coming from the darkly colored mech...

"Good news is, the project is running at one hundred percent... bad news..." He looked to the big mech "We detected a spark signature in the shell...

-Impossible!" That new voice, high pitched, and screechy was making her cringe. The white mech stepped forward the monitor still talking:

"You say you didn't built a spark chamber!

-I didn't... we didn't..." He turn quickly to the others workers as to check something, before returning his attention to the complaining mech. "None of us have.

-And yet you detect a spark signature?

-Could be a glitch in the scanner..." he shook his head before looking at what appear to be the leading mech " Anyway, I need to put up some more test... just to be sure..."

Finally the grey mech spoke:

"Do what you need, I want this project functional... I waited too long to have it failed now..."

And he turned to leave, motioning to the screechy one to follow him.
However the Dark mech still had a last question

"And if... it's not a glitch?"

The door opened and the giant mech stepped outside before answering:

"Then we will have to deal with it..."

During the whole exchange she had stay put, not knowing what to do, her gaze bouncing from one talker to the other. Now she was following with acuity every move of the remaining one, as he came closer to her.
He put some tools down on the little table, and began to type some code on the nearest console.
When the machine biped, he took what looked like a screwdriver, and with a small smile he began to remove her front panel.
She was still watching, unsure of what to do.

In fact she wasn't sure of anything except the basic program running trough her processor and her designation, embedded in front of her vital program.
Finally having removed th last peace of her chest armor he began to fidget inside, until a blue light illumine his hand. He let escape a small sound of surprise.
Well you know what? It have a spark... and no spark chamber... That's got to be the weirdest thing I ever saw...
He put the tools down, monitoring the console screen during another cycle, pushing some button from time to time, and sending some jolt and information trough her circuit.
Finally he shut off the screen, and ordered to every other scientist to leave, then he turned to her again whispering for himself:

"He is not going to like this..."

He finally headed to the exit door and before it closed, he looked at her a last time. Their optics crossed for the first time and it was like if...
He shook his head. Now I'm making thing up out of nothing... working for the Decepticon is getting on my nerves...
But as he was making his way to the throne room he was sure of two thing about the project:
First it have a spark.
Second... It could stare back...
