Nos smiled. Now was his chance. Ruby had tried to stay awake the whole night, but ended up falling asleep. Nos slid one of the windows open and crept down the stairs, listening for a moment to make sure they were really asleep. He hoped Aya wasn't a light sleeper as he wrapped his arms around her and hungrily dragged her off.

He was almost out of the house when Aya suddenly screamed, "RUBY! RUBY HELP! HELP ME!"

"Shut up!" Nos hissed, bolting as fast as his wings would carry him.

"Aya!?" Ruby found Nos' eyes and brandished her weapon.

Nos cursed under his breath, flying faster and faster while Ruby shot melting explosives at him, "LET GO OF MY SISTER, YOU SICK FREAK OF NATURE!"

"HELP! HE-MMF!" Nos covered Aya's mouth as she kept screaming.

"Be quiet!" Nos growled as he flew back and forth, trying to outrun Ruby's angry blasts.

He hit a wall, "No!"

"Gotcha, ratchet!" Ruby cocked her powerful weapon, "Unhand my sister now!"

"Ugh!" Nos held Aya in place in front of him, like a shield, "Get out of here!"

"Nos-4-A2..." Ruby said in her dark and serious voice, "Give my sister back...or I will make your death very long and painful..."

Nos brandished his fangs, "I'm not giving up so easily..."

"Ruby! Help! I'm scared! What if he kills me!?"

Ruby advanced and Nos jumped forward, deciding to try something reckless. He held Aya firmly in his left arm and grabbed Ruby with his right, sinking his fangs into her crevice of a neck.

Ruby screamed.

"Ruby! NO!"

Nos didn't bother draining all her energy, instead dropping her body on the ground and flying off again.

Aya shook with fear, "A-are you going to k-kill me?"

"Not if you cooperate." he replied, "Stay calm and no one else gets hurt."

"WHAT!?"

"I'm so sorry!" Ruby rubbed the bite marks on her metal casing, "Ack! This hurts! I can't believe I failed!"

"You're telling me that Aya is in the hands of an energy vampire!?" EVE screamed, "ALL HANDS ON DEEECK!"

Eve!? M-O hurried to her, What's wrong!?

"Everyone! Aya's been kidnapped by Nos-4A-2!" EVE explained.

The energy vampire!? M-O glanced at all the rogue robots.

"That's horrible!" Leah shifted Ted in her arms, "We have to save her!"

"He was able to overpower Ruby!" EVE said, "We need everyone on board if we're going to get Aya back!"

"I can't, though!" Leah said, "I still have to watch Ted!"

I don't want to go up against an energy vampire! M-O shivered in fear.

"Well we have to do something!" EVE hurried away, "I have to gather everyone!"

"Everyone?" Rose asked.

"Everyone! Gather everyone!" EVE repeated.

She wasn't letting her sister get drained of all her energy.

"Ugh! Why won't you hold still!?"

"Please don't bite me!" Aya pleaded, "Please don't drain all my energy! I'll do anything! Just don't hurt me or my family!"

"I said, SHUT UP!" Nos shoved her into a steel cage, locking the door tight, "I swear, some of my victims give me the worst headaches!"

He had dragged her all the way out into the wasteland to his ship near the outskirts of discovered land itself. It was a ship he had taken over since no one else was occupying it. It now acted as his base of operations. He made sure to cover Aya's face so she couldn't see where it was located.

Aya blinked, holding the bars of the cage as he hovered away, "You're not going to hurt me?"

Nos' optic furrowed in frustration, "No. I'm going to figure out what makes you so resistant to my wireless mind control first."

Aya frowned, her hold on the bars relaxing, "Are you going to kill me?"

"Emotion will get you nowhere, little one." Nos began to type on the keyboard nearby, "Now hold still."

A laser swept over Aya and she saw her form on the screen. Nos' eyeforms narrowed upon seeing it.

"Will you kill me after this?"

Nos turned to her, not bothering with his usual cocky smile, "Yes. I need the energy. If I have to eat one more battery, I think I'll vomit."

Aya looked down at the floor, "Why?"

"What?"

"Why are you doing this?" Aya asked carefully, "What did I ever do to you?"

Nos was surprised by the question, but he didn't show it, "You defied me. I want to figure out how, and then I want a decent meal. Those sentries give me nothing."

Aya blinked in horror, "That's it? That's how you play with people's lives!?"

Nos let out a breath of air, "Just be quiet. I'm trying to focus."

Aya watched Nos pull a large battery out of his coat pocket and bite it, sucking it dry and tossing the empty canister behind him. It rolled over to Aya and she scanned it, worry crossing her eyes. There wasn't a single drop of energy left in that battery.

Nos stuck his tongue out, "Bleck! I hate the taste of batteries."

Aya listened passively as Nos' fingers clacked away at the keys. He looked at all her inner workings, how it all worked, how it was put together. It surprised him how complicated it was, considering Earth's history with robotics. It was interesting to him how he'd never discovered this level of complexity before.

His mind was working well at first, but then the lack of sleep caught up to him and he yawned, "Ugh...I really want to bite something right now..."

A chill ran through Aya.

Nos leaned forward and bit the machine in front of him, sucking the life out of it until the screen shut off. He was bone tired.

"N-N-Nos-4A-2?" Aya shivered.

"What do you want?"

"A-Are you tired?"

"Well, I was awake all day looking for the opportunity to grab you. Yes, I'm tired."

"So Ruby was right..." Aya wrung her hands together as Nos began to leave, "Wait!"

"What!?"

Aya flinched, "Did you kill Ruby?"

Nos rubbed his forehead, "No, she isn't dead. I didn't take enough power to drain her completely. She'll be fine. Now will you let me go to sleep!?"

Aya furrowed her eyebrows, averting her gaze, "Right. Sorry."

Nos glared at her before disappearing around the corner, towards the living quarters. He didn't need a specific place to sleep - he could pretty much sleep anywhere - but he liked having one place to return to when he was tired. He flopped down onto the bed, still feeling very hungry. He was out like a light though.

He would deal with all of this in the morning.
