Lab Rats

Chapter Two

Ed didn't wait for a response. He glanced around the room slowly, noticing that only in their cells was light. After a few minutes of what seemed like thinking, he turned back to Envy. "Where are we?"

"Why the hell do you think I would know?" the Sin deadpanned. "I am in the same predicament as you, Pipsqueak, as you can see." He moved to the best of his ability, showing him that he was also tied up.

"WHOAREYOUCALLINGSOSHORTTHATTHEYCOULDHIDEUNDERTHETINYDUSTFLOATINGINTHEAIR?!?!"

There was a long silence that followed Edward's rant, not to mention an echo that lasted just as long. Finally, Envy grinned. "You."

The alchemist growled, but then let out a sigh. "We shouldn't be arguing-"

"-This is arguing?-"

"-We should be finding a way to get out of here..." he continued, ignoring the Sin's input. Ed mumbled to himself as he tried to untie his arms. The process didn't last long, he had experience of undoing rope even prior to his acceptence into the military. It didn't take long for him to break free from the bound, without the use of Alchemy.

He grinned his trademark grin as he rubbed his human wrist gently. The binding had left small indents. "I'm surprised they let me keep my automail..."

"...Are you talking to yourself, Pipsqueak?"

"..." Edward ignored Envy's question, and walked over to the bars of his cell. "Now...To get out of here..."

"...They say it's a first sign of insanity, you know..."

"Or really?" the other asked, glaring at the Sin out of the corners of his eyes. "Well, I don't see you adding any useful information anytime soon."

Envy shruged lightly, whincing slightly as he did so. 'Damn nodes...' he thought regretfully. "I thought it would be funnier to watch you fail."

Edward raised an eyebrow, and turned to him. "What do you mean...?"

"It's pointless," the other mumbled, closing his eyes. "They know our weaknesses. Both mine, and yours."

Now that caught the alchemist's attention. "I thought homunculi didn't have weaknesses." It was true, they were very good at hiding them. However, Sloth was not that hard to kill. He had used his mother's ashes, and turned her into ethanal. But this Sin was over 400 years old, and the chances of finding his remains were close to none...

'They must have another weakness...' he thought. Golden eyes then examined Envy. The dim light had made the Sin's skin a sickish yellow, but he pasted that off as nothing. His gaze went lower until it reached his thigh. Ed's eyes widened in shock.

"Like what you see?" the homunculus sneered. He glared at the human for a moment, then looked away, ashamed at himself for letting out one of their biggest secrets.

"Y-Your...Your oruoboros!" Edward whispered, a bit surprised by the thick needle burried in it. It wasn't too deep, from what he could see, and it also looked like it was slowly edging out of his skin on it's own. "So...You can't shape shift?"

"No, I can't, dip shit," the Sin growled. For a prodogy, the kid lacked common sense. "I can barely move! And I hate it because it makes me feel like such a damn weakling!"

Edward chose to stay silent. Truthfully, he could say so many things to insult Envy, just as the homunculus had done to him countless times, but he figured it would be best to be the more mature captive. He turned his attention back to the bars before him, and gasps two with his hands. "You said they know both our weaknesses."

Violet eyes met with gold.

"But I still have my automail."

"You have other weaknesses other than your hunks of metal," Envy mumbled, and closed his eyes, cuting off their connection. He was quiet for a moment. When he opened his eyes again, he said, "Try using alchemy on the bars."

Ed raised an eyebrow curiously, but did as he was told without any questions. He clapped his hands together just as always, and then put them against the bars. Immediately, he jumped back, holding his human arm and panting lightly. To his right was a snickering noise, and he glared at the laughing homunculus.

"What a shocking discovery!" Envy giggled, and sighed contently as one of the spikes fell out of one of his back nodes.

Edward growled, and thought the Sin was quite lucky that there were bars between them. "You knew that the bars were going to shock me if I used my alchemy, didn't you!?"

"Ah...No," the other confessed, "I didn't. But I did know it was going to be entertaining to watch you fail."

The alchemist took a look at his human arm. It was scratched here and there, and at some parts bleeding a little. He only had one small burn on two fingers. There was no doubt that he had some burns around where his automail connected with his shoulder, but he would have to check there later.

"Got any more smart ideas?"

"Stilts will help you appear taller?"

"...."

"Heh, lighten up, Pipsqueak." Envy thought for a moment, but his concentration was broken when his ears picked up the same pair of high heeled shoes from before. His smirk fell to a frown and violet eyes narrowed.

"Envy?" Ed asked, feeling a bit left out. Human senses were nothing compared to those of a homunculus'.

"She's back."
