Damon POV

I heard a loud scream coming from deeper in the woods, it sounded like Elena. As I got there I saw Katherine bite a girls arm, it wasn't Elena but it was her sister.

I shoved Katherine off of her and she growled at me as she launched herself at me. I grabbed her neck and smashed into the tree causing it to shake wildly. Her face went back to normal and she smiled it made me sick.

"Hello Damon" she said trying to be seductive.

I slowly pulled a stake out of my jacket as I leaned into her making her think I'd kiss her. "Goodbye Katherine" I whispered into her ear and stabbed the stake into her stomach. She gasped and fell to the floor, and tried to slowly pull out the stake.

I turned to Bella who was knocked out, Katherine must have drained her. I picked her up and noticed that her head was bleeding. I ran through the forest to my house. I laid her down on my bed and she was still unconscious, I needed to give her my blood, Elena would kill me but if I didn't she'd kill me either way.

"Damon! What happened to her? I heard her scream and I saw you carrying her and I ran here." Caroline panted as she made her way to Bella's side.

"Katherine attacked her, call Stefan and tell him to bring Elena now!" I ordered and she shook her head fast as she pulled out her phone.

I went into my closet and I got a white shirt and ripped it into strips to wrap around her head and arm while Caroline called Stefan.

I turned to Caroline, "Stay outside; she's bleeding… a lot." I added and she turned to me as she hung up the phone.

"I can handle myself! Stefan has been helping me out." She shot back and made her way over to Bella again. "Give her blood Damon she doesn't look to good."

I rolled my eyes at her, "She barely has blood in her system what do you expect her to look like. Where the hell are they?" I asked her frustrated as I bit my wrist and forced it into Bella's mouth who drank my blood willingly. I tried not to show how much it hurt since Bella was almost biting my flesh. My head shot up when I heard Stefan, Elena and Bonnie at the door.

"We had to drive here, Bonnie wanted to come." Stefan said his worried face looking much worried than usual.

Elena nearly jumped Bella who was still unconscious, and Stefan followed behind her. She was crying, "Is she okay Damon?"

"She'll be fine, I had to give her blood Katherine nearly killed her." I explained softly. "Elena you can't be here when she wakes up, she thought you were Katherine."

Elena gasped in shock, "What? What am I supposed to do then? I can't tell her about all this, she can't know" she said shaking her head. "She's my only family." She whispered.

"Well if you don't tell her you're gonna loose her." I explained to her.

"What do you mean only family?" Bonnie asked as she crouched down next to her on the side Bella was laying.

"Bella's her sister." I said and looked at Elena confused. "They don't know?"

Elena shook her head, "Bella thought that John didn't want anyone to know about it yet." She mumbled with her head down.

"Wait she's John and Isobel's too?" Caroline asked confused.

"My twin" Elena answered as Caroline and Bonnie looked at her shocked. She looked up at me as Stefan rubbed her back, "Tell her, I can't have her hate me. I'll leave when she wakes up."

"Damon you wrapped the wrong hand." Bonnie said as she pointed out a bite mark scar Bella's hand.

I took my wrist out of Bella's mouth since she didn't look paler than she already is.

Bonnie let out a gasp when she touched the scar on Bella's other arm, she immediately let go of her arm and looked up at us.

"Do all vampires have veins that pop out?" Bonnie asked with wide eyes.

I looked at her anxiously, "What are you talking about?"

She hesitated, "I saw this guy… when I touched her scar. He was biting her arm, there was fire. Do you know what might have happened?"

I reached over and to see the scar it looked like a bite mark, it felt colder than her body temperature.Strange.

Never in life have I heard anything like this before, I shook my head. "No, is that all you saw?"

"Yeah that's all." She answered shaking her head as she still looked shocked from the vision.

I felt Bella squirm from beside me, we all looked at her. She looked like she was going to cry, she sniffled and mumbled "Edward".

"Who the hell is Edward?" I asked annoyed. I hated that Bella was such a mystery, I know everything and she just happens to be a mystery to me. Who was this Edward guy, and why was she so upset?

"I don't know…" Elena whispered looking at Bella cautiously, probably waiting to see if she was gonna wake up.

Just like Elena had expected, all of a sudden Bella bolted up and looked around. She looked at her arm to see it wrapped but she tore it off to see the scar gone. "Where am I?" she asked beginning to panic as she saw Elena.

"Okay that your cue to tell." I told Elena who got up and walked out with Stefan sadly. I turned back to Bella. "She attacked me!" she gasped as she remembered what had happened to her.

I shook my head, "You were attacked, but it wasn't Elena." I explained and then I realized it was the stupidest thing I've ever said. You were attacked, but it wasn't Elena. Oh yeah that sounded believable Damon.

Bella looked at me, "I know you, Damon Salvatore?" she asked. "Where am I?"

I smiled, "The one and only. And you're in my room." I answered her with a wink and she began to blush then her eyes quickly widened.

"Bella are you okay? Do you remember what happened?" Bonnie asked concerned. Bella turned to her and pulled her eyebrows together as she thought about it.

"I was with Tyler, he went to get us drinks then Elena came there dressed differently. All of a sudden she had these things come out of her mouth and veins were popping out of her eyes. Some idiot knocked me out of the way and I remember blanking out." She told us calmly as she thought about everything.

Caroline bursted out laughing and Bonnie giggled as they shared a look. "I wonder which idiot?" Caroline asked trying to hide her laugh.

I rolled my eyes, "Weren't you scared to see all that? I happened to be there at the right time to save your ass, you could have died you know. What were you thinking? Alone in the woods at night?" I asked her slightly irritated that she called me an idiot. There was something seriously weird about Bella.

"Oh, Thanks…" she said blushing. "I'm not scared, and I wasn't scared. And I wasn't alone. Tyler was with me you know. Oh my gosh! Tyler, is he okay?"

"Ty is fine, if you weren't scared then why did you scream?" Caroline tested her.

"No you're right, I should have laughing." Bella said sarcastically and rolled her eyes, she looked back down at her arm, "What happened to my arm? There should be a scar?"

Bonnie looked at me and I sighed turning back to Bella who was looking at us for an answer. "Bella, can you keep a secret?" I asked as she looked at me oddly and chucked.

"I've heard that before." She whispered softly, probably to herself. "I know I barely know you, but you can." She answered me confidently. There was some kind of a message in her voice telling me that I can trust her.

"I trust you, don't make me regret it." I told her sitting up now infront of her.

"It wasn't Elena that attacked you, it was her… doppelganger." I paused to see her reaction, her face held the same emotion as before. It was blank or just hard to read. "Do you know what that means?" I asked her and she shook her head.

"Someone who looks like you, like a twin… A double-walker, wait what if you have the wrong twin? What if she's the one and not me?"

I laughed at this and they all stared at me like something was wrong with me. "That's impossible, she's way too old. That's what I need to talk to you about. Do you know what Katherine did to you?"

She closed her eyes while rubbing her temples and sighed, "She bit me."

I rolled my eyes getting frustrated, "I know that, but what happened when she bit you?"

Bella frowned lightly and said, "Sucked my blood."

"She has fangs; she sucks blood… does that ring a bell." I asked as she chuckled.

"What are you trying to get at Damon?"

"She's a vampire, Bella. I know it's hard to believe but yes they do exist." I explained to her, but she began to shake her head.

"Nope, that's not possible. What time is it?" She asked changing the subject as she crawled passed me and got off the bed.

"Damon! She's doesn't believe you, Elena gonna be so upset." Bonnie whispered to me as Caroline shook her head agreeing with Bonnie.

"I'm trying my best here; I don't want to scare her either. Why don't you ask blondy to do it? She's a vamp too." I whisper shrieked and got off the bed, I looked at my phone and it was 1:00am.

"Wow, it's one in the morning. Bella, listen to me it wasn't Elena okay. It's Katherine, Elena's Doppelganger and she's a vampire, but I need you to keep this a secret." I explained to her.

She shook her head. "I'm gonna stick with doppelganger. She can't be a vampire… she just can't. Where's Elena?" She asked walking past me. "I need to get home, I think Jenna might kill me."

I groaned, why was she so stubborn? "Elena is downstairs with Stefan. Listen I know it's all crazy for you to take in right now. But why can't you just accept it for what it is? You know what happened, what more do you want?" I asked her.

She walked back to us. "Listen, I don't want to sound rude. But please stop with the whole vampire thing okay? I came here for a fresh start and avoid drama, and this isn't helping cause this is exactly what I want to avoid." She looked as if she might cry. "But thanks, for helping me." She thanked me and turned to leave following Bonnie out the door.

Caroline sighed just as frustrated as I am. "At least she knows that it wasn't Elena right? That's good for now. I'll have Elena talk to her, she'll probably believe her more than us." She said then followed the others out the door.
