Chapter One; Ethan's POV

"Benny, it is not possible to..." I stopped, looking out my bedroom window, "Benny... you'd better see this!"

Benny walked over to the window and looked out. "Dude, I think there's a girl passed out on your front lawn." he said casually.

"Really? I thought it was an elephant."

"How would an elephant get... oh. You were being sarcastic."

I rolled my eyes. "Come on." I walked quickly out of my room and down the stairs.

When we got to the lawn, I knelt next to the girl. I carefully turned her onto her back. My eyes widened. "Benny..." I started worriedly, "I think this is my cousin."

"You think?" Benny said skeptically, "How do you not recognize your own cousin?"

"I haven't seen her in four years. We used to talk a lot and then... she just disappeared. Never had anything to do with our family ever again." I looked at her closely, "That and the fact that she has multiple cuts and bruises..."

Her face was cut and bleeding and her clothes were torn. "Help me get her inside." I added, picking her up.

We put her on the couch in the living room. "What exactly are we supposed to do with her?" Benny asked, poking her face.

She groaned and slowly opened her eyes. "Why?" she asked quietly, "Why did you poke me?"

"Uh... just trying to wake you up..." Benny replied nervously.

She looked at me. "Who... Ethan?" she asked in shock.

"Yeah... Ada?"

"Yeah... I gotta go." She sat up, wincing in pain.

"Go? You're hurt... and we haven't seen each other in four years. I thought we could talk."

She closed her eyes. "About what?" Her voice was quiet and I knew she didn't want to talk.

"About why you left without evening saying goodbye."

She sighed. "Things just... happened, Ethan, and I had to leave."

"Why?"

"If I told you... you'd think I were a freak..."

I glanced at Benny. "You wanna bet?" he said, hiding a smile.

Ada suddenly gripped her stomach. She pulled her hand away and saw blood. "Um... where's your bathroom...?" she asked, visible pain on her face.

"Through the kitchen, first door on the left," I replied.

She got up and walked out of the room quickly.

Ada's POV

I walked to the bathroom quickly as a familiar sharp pain raced through my chest. "No... no, not now. Please." I muttered, locking the bathroom door.

I looked at the mirror. At first, there was nothing, then a darker version of me appeared. She smirked at me. "Having a fun time, Ada?" she asked mockingly.

"Shut up," I growled, taking a washcloth from under the sink, "Go away, Ava. Please. You can't show up now..."

She smiled wickedly. "Too late..."

A fiery pain shot through me and I blacked out.

Ava's POV

I looked down at myself and smiled. "I'll be sure to be... nice, to your cousin, Ada." I said, putting down the washcloth Ada had picked up.

Ada appeared in the mirror. "Do not go near him!" she demanded.

I laughed and opened the door.

"Ada, are you alright?" Ethan asked me as I walked into the living room.

"Of course, I'm perfectly fine, Ethan." I replied, smiling at him.

'I told you not to go near him!' Ada told me telepathically.

'And... how often to I listen to you?' I replied.

'It wouldn't kill you to start...'

'I beg to differ. It could destroy me.'

'I don't see what the problem is.'

"So... where are your parents, Ada?" Benny asked.

Ethan elbowed him in the ribs. "Oh, uh," I quickly scanned Ada's memory, "They left me when I was a baby. Put me in the foster system and... never contacted anyone in my family ever again."

"Sounds familiar." Benny muttered.

'Ok new rule,' Ada said madly, 'Do what you want with that one.'

'Finally I get to have some fun.'

I glanced at Benny, imagining him as a toad.

"Ada, do you need like, a hospital or something...?" Ethan asked.

"No," I replied, "I'll be fine, honest. I just need something to drink."

'No! You will not do that to them!"

I rolled my eyes. 'You said I could do what I want with Benny...' I pouted.

'Yeah, but draining them is not an option!'

"Benny, would you mind coming with me?" I asked sweetly.

He smirked at Ethan and said, "Sure, no problem."

He followed me into the kitchen. I turned to face him. "So... Ethan's curious about why I left...?" I said, stepping closer to him.

"Yeah... can you tell me why?"

"You really want to know?" he nodded, "Ok."

I smiled and turned. I walked a few steps. "I may scare you..." I said tauntingly.

"I doubt it."

I looked at him and smiled. His eyes widened. You're a... what?!" he said in shock.

I ran up to him and tried to bite his neck. He pushed me back sharply. I hissed at him.

'Stop it!' Ada yelled, trying to take over her body again.

A shooting pain raced through me and my eyes turned red with angry. "No..." I growled. I tried to fight Ada back but it had taken most of my strength to take over her in the first place.

Ada's POV

I fought Ava and eventually was able to overpower her and take over. I feel onto my knees, weak and tired. "Oh no..." I muttered.

"Ethan! Your cousin tried to bite me!" Benny yelled nervously.

Ethan ran in. "What are you talking about...?" He asked worriedly.

I looked up at them. "It wasn't me..." I said quietly.

...

So that's all I got for now. Basically it's like... Chase and Spike from Lab Rats, but different.
