It was a dark day at Beacon Academy. Two pupils from different schools had been found dead and mutilated. People were warned to stay in their homes at night and report any suspicious activity to the police or huntsmen. Everyone had been affected by these tragic loses… Except for one person. Penny happily walked through the streets of Vale with a smile on her face. She had never been this happy before. All thanks to the generous contributions from Ciel and Velvet to her anatomy. After hearing the news, Penny realised she had to be more careful. People would be more vigilant. And she couldn't have that, could she? Penny thought of who to go after next until she spotted her best friend, Ruby. Penny's eyes lit up with joy.

Ruby was looking very upset. She was wandering the streets taking her dog Zwei for a walk. The little corgi ran around the streets, looking very hyper. He spotted Penny and ran up to her, barking happily.

"Salutations!" Penny greeted Zwei. He was of no use to her. Penny needed human parts and not animal parts.

Zwei continued barking.

Ruby saw Penny and walked up to her and Zwei, still looking sad. "Hi Penny." Ruby said quietly with a little wave.

"Hey Ruby!" Penny noticed Ruby's sad expression. "What's wrong?" She asked with genuine concern.

"Didn't you hear? Velvets been killed… The girl we met yesterday." Ruby said as her voice trembled and a tear fell down her cheek.

Penny's eyes widened. She thought for a moment. "Oh no…" This was her doing. She made her best friend cry. But she couldn't spoil her surprise for Ruby. Penny was now very conflicted on what to do. She decided to act innocent and surprised as a cover up. "What!? That's… That's horrible!" She said with a fake shocked look on her face.

"I know…" Ruby said looking down. "Velvet's gone and everyone's afraid of some serial killer roaming Vale."

"How are you holding up?" Penny asked. "I know you two were friends." Penny put her hand on Ruby's shoulder.

"I'm… I'm coping." Ruby said as she put on a brave smile. "What about you? I heard Ciel was found. You two were close right?" Ruby asked.

"Oh." Penny said with a surprised look on her face. "We were… More acquaintances than anything. It hurt at the time but I'm recovering."

Zwei continued to run circles around Penny and Ruby. He then waddled over to Penny and started sniffing around her legs. Zwei started growling.

Penny, realising that Zwei had caught her out, gently tried to push him away.

Zwei persisted and growled even louder.

"Ugh… Easy boy. Good dog?" Penny tried calming Zwei down.

Ruby stepped in and picked Zwei up. "What's gotten into you today?" She looked at Zwei who then started licking her face. "Ooooh… I can't stay mad at you!" Ruby said as she petted Zwei. She was now very happy. "Sorry about him Penny."

Penny's eye twitched. This mutt was giving his love to Ruby. Penny's best friend, Ruby. This was unacceptable! Ruby was Penny's friend! No one else deserved her! She couldn't allow them to give her their inferior love and friendship. Something had to be done about this dog…

"Penny? Are you ok?" Ruby asked with concern.

Penny snapped out of her thoughts. "Oh. Yes. I'm fine, Ruby. Hiccup"

"Got the hiccups again?" Ruby asked with a slight giggle.

"Um… Yes. That's it!" Penny exclaimed trying to act natural.

Ruby squinted at Penny. "Ok… I'll see you soon, Penny. Take care." Ruby went in to hug Penny with Zwei still in her arms.

Penny hugged back. "Take care, Ruby my friend!"

Zwei sniffed Penny's human arm and growled again.

Penny swiftly exited the hug. "Goodbye!" Penny said as she quickly walked off in the opposite direction of Ruby and Zwei.

"Bye!" Ruby shouted to the quick footed Penny. She then held Zwei in front of her. "You shouldn't growl at Penny. She's our friend!" Ruby scolded Zwei.

Zwei whined slightly and hopped on to the ground, waddling ahead of Ruby with a happy bark.

Ruby followed her canine companion down the street.

-Team RWBY's dorm room-

In the dorm room at beacon, everything was quiet. Ruby, Weiss, Blake and Yang were all fast asleep. The little corgi, Zwei, lay sleeping on Blake's bed. It was 3am and very dark.

Suddenly, a small head appeared from outside RWBY's window. It was Penny who had easily scaled the wall and made it up to the window. She was out for this mutt's blood. Penny looked around to make sure nobody was watching her. Security had been increased ever since Ciel and Velvet were found so Penny had to be vigilant. Then, Penny easily opened the window. Thankfully it was unlocked which gave her easy access to the dorm. Silently and stealthily, Penny crept in from the window sill and into the room. She made sure not to make a sound. One wrong move and she would be trapped in a room with four angry and well trained huntresses. Penny's artificial vision could see clearly through the dark and she easily located Zwei. Penny knew that Zwei would put up a fight with lots of barking involved, so she had to make this knockout a quick one. She brought the necessary supplies needed: Her trusty chloroform and a sack big enough to fit a small dog in it.

Penny approached Zwei who was sitting at the foot of Blake Belladonna's bed and readied her rag. With a quick strike, she forced the rug over Zwei's entire mouth and grabbed him tightly.

Zwei instantly woke up and started to struggle and bite Penny.

This did not affect Penny and she ran out of the room window, closing the window behind her without a trace.

Zwei shook and struggled in Penny's arms but the chloroform was starting to take its toll on the little dog, making him slower and more tired.

Penny jumped down from the window sill on to the grass below, squeezing Zwei tighter and tighter. She didn't need anything from him. She just wanted the dog to suffer for trying to come between Penny and her best friend. Penny squeezed the life out of poor Zwei, crushing his ribcage and some organs.

Cracking and crunching could be heard as muffled yelps and whines tried to escape from Penny's grasp. Zwei couldn't take much more of Penny's unrelenting punishment and slowly passed out.

Penny, satisfied with her current work, threw Zwei into the sack and carried him off.

-Vale docks-

The docks in Vale were always empty at night which meant Penny could finish this job cleanly. She had the sack containing the crushed and unconscious Zwei over her shoulder as she made her way to the Pier's edge. The water was surprisingly deep at night with the tide coming in. Perfect for drowning a dog. Zwei would regret the day he ever touched Ruby. Penny took the sack and held it high over the pier's edge above the water below. Without any mercy or remorse, Penny dropped the sack and heard a small splash as Zwei hit the water and eventually sank to the bottom. Penny smiled with an evil grin. She had taken out the competition and was now another step closer to being Ruby's true best friend. Satisfied with her work, Penny made her way back to her room on the Atlas ship and powered down for the night. There was no stopping this emotion-fuelled machine.
