Day four of seeing this human, and Soundwave found that she did indeed rest. He was able to visit in the middle of the day, the Nemesis coming near the location already. It was this time he realized was when she recharged. The mech wondered if he'd be able to send a message to anything within the bunker beneath the rock, but it was unlikely if they couldn't detect the energon unless she opens her entrance to the place. He contemplated tapping on the metal door, but there was a reason she was so quiet as a scan revealed the fallen slate to still be quite unsteady. Making too much noise may cause it to fall and cover the entrance. 

         :Soundwave: Megatron called. :If the pest isn't there, I have other projects at hand:

He received no answer, but the war lord didn't expect one. Soundwave decided it was a fruitless endeavor to wake the human from her slumber, transforming and taking to the skies.

     He landed without trouble, his peers staring warily. Most continued their work along the flight deck, though any who deemed themselves to close to the silent mech slowed their work. Soundwave paid no mind to them. He entered the halls with little trouble, aside from a group of Vehicons feeling like having to scatter from his sight along the way. 

     Laserbeak crooned within their bond, making Soundwave aware that he was returning from another false energon signal. The mech was disappointed but did not pin any failure on Laserbeak. Instead, the lithe mech ordered him to search another signal close to his current location. The aerial being chirped his affirmative before the bond numbed to a comfortable quietness. 

     The famed TIC entered the medical bay, finding Knockout speaking with Megatron about a topic unimportant to his current tasks, so Soundwave took no note of the conversation. Megatron saw his most trusted and halted the conversation short, turning to the purple mech.

         "So, the human was not awake." He noted. "From what you've explained of the creature this female is rather intelligent."

         "But slow to think." Knockout had been tasked with examining her behaviors as research for the experimental human forms. "I say there's something deficient in her central processing unit, or brain." He gagged at the thought of the squishy, wrinkled, gooey mass within the human's skull. "She doesn't exactly do much for body language, unlike those three Autobot pets. Her expressions are zip and to be frank this human femme is quite... bland."

     Soundwave understood her behaviors to be quite odd, but these human forms were only temporary. Having these false bodies expressionless and with little personality would be ideal. Not that the Communications Officer believed anyone would become attached to these forms, but the precaution was well placed. 

         "The human will have served its purpose soon enough." Megatron stared blankly at the computers, not really reading anything it had to show. "Once this project is done it will most likely escape elsewhere, crawl back to M.E.C.H. or die. Whether it be by my servo I have not decided as of yet."

     Megatron's most trusted saw no reason to murder this human, but if his master were to choose to end her short life than so be it. At least then she was less likely to be found by M.E.C.H., something he knew she most likely feared, despite her lack of expression. Soundwave filtered through his conversations with (Y/N) as he stood, waiting to be dismissed as Megatron spoke with Knockout again. Her voice always remained steady, rather flat, but from time to time an undertone of hatred or anger would shine through her words. Soundwave didn't believe he would draw a comparison between him and this human, but clearly, like him, she was quite mildly tempered unless trifled with wrongly.

         "Soundwave," his leader spoke once more, "I want you and Laserbeak to search those mountains for any possible human dwellings. I'd rather have this operation to go as smoothly as possible. Any human dwellings besides our current informant will only delay the process with their inevitable annihilation."

     The mech nodded, turning at his usual pace before calling Laserbeak to return. 

     He was rather puzzled, as he thought further about this strange human. He did not think on it before, but her behaviors were much like his before the war. Still speaking, though not often. Only when asked something, truthfully. Intelligent and holding information that could be dangerous in anyone's hands. How much she truly knew, Soundwave was unsure. 

        He did not like this fact. 

     It frustrated him how she withheld information so easily and still made a conversation seem complete. It takes a well taught or well learned spy to learn these tricks. For Soundwave it was not hard, as he was not one to speak anyway, but humans are notoriously weak minded and easily coaxed into giving answers when properly pressed. They certainly wouldn't survive most or any Cybertronian tortures. Granted most were null and void considering their greatly different anatomies. Then again, M.E.C.H. was notorious for their Cybertronian experiments, and tortures. If Breakdown wasn't proof of that than Soundwave was no better than Starscream (a truly preposterous notion). M.E.C.H. more than likely put this human female through many tortures to determine her trustworthiness and mettle. In other words, her straightforward yet incomplete explanations had become second nature. 

     The purple Cybertronian halted in his path to the outside world as he thought. A rare occurrence, but revelation would sometimes cause the mech to ponder on one lone topic. If this human was truly as skilled as she let on, despite her slower thinking and unfortunate size, she could be a useful asset to the Decepticon cause. A spy. Some modifications would have to be made, of course, and an alias manufactured, but it could work. He just needed leverage to ensure this human femme did not betray them to the Autobots if she were to gain any information aboard the Decepticon vessel.

     Soundwave continued his ascent to the flight deck, Laserbeak informing him he had arrived at the mountains, well hidden from (Y/N)'s dwelling, as they were still wary of her. The mech smirked beneath his visor, a rare thing even with the blackened void covering his faceplates. All he needed was a way to contact M.E.C.H. and (Y/N) (L/N) would be as a puppet on a string.
