Sorry for this update taking so long, but my real life kept me from writing:( I started this chapter with a desire of writing an epic battle between John and Nikola, and I ended up writing a battle between Helen and John- not so epic as I would have intended, but I hope you'll like it anyway. As for Helen's new power, well, I have some plans for using it in the last chapter, and that's the main reason I gave it to her, but I'm not going to spoil anything! Thank you for all your great reviews!

Staying there, in the living room, waiting for them to come, made Helen a little worried. She knew that she was now immortal, but John had managed to defeat Nikola once for a while, even if he had been in his vampire form. What would happen if he did the same now? How would she be able to protect Nikola? When John and Dana finally teleported inside, she gripped Nikola's hand and realized that she has to fight and win this battle. For him, if not for her.

"You are both alive." Said John coldly. "I must say I am disappointed."

"We are sorry to disappoint you, Johnny, but we managed to get past Helen's transformation."

"John, listen to me. " said Helen."I know that you are angry and jealous, but this doesn't mean you have to kill us. This is not you. It's that thing inside you. You have to get rid of it. I will help you, but you have to let me do it. I know that there is a cure. If I could be cured of my vampiric lust for blood, you can be cured too."

Don't listen to her, John. She wants to kill you. She doesn't love you anymore, John, she betrayed you. Just like every woman in your life. You know how women are, John, and you used to help changing the world. Remember? Do you remember Mary, Catherine, Annie and Elizabeth?

"SHUT UP! " he yelled. "That wasn't me!"

You enjoyed the smell of blood that lingered on your hands; you wanted to see their look on their face when they realized that they only have a second left to live, you liked laughing at the face of those idiots from Scotland Yard that didn't manage to catch you, even at the face of your colleagues, especially James, you loved feeding them with incorrect theories. That is the real you, John. You can't let anyone change you. Not even Helen.

"Do you love me, Helen?" he asked, trying to ignore the voice in his head.

"No, John. Not anymore. I made a choice, John, and I didn't choose you. I'm sorry, but you changed, John. You are not the man I fell in love with."

"I told you that she doesn't love you." said Dana. "But since I am in a good mood today, I am willing to deal with you. You can live with your precious Nikola, but you'll have to hand over the Sanctuary network."

"I'm sorry, Miss Whitcomb, but I am not willing to deal. Not this way. You lied to me. You said that if we inject her with the Source Blood she'll listen to us. Not jump in his arms."

"The problem with you English people is that you don't understand how powerful love is." Said Nikola.

"Hey!" said Helen, a little angry.

"I'm sorry for that, Helen. I will rephrase. English men don't understand love."

"That's better."

"You mean you didn't kill him because you love him?! Helen, are you serious?"

"I was never more serious in my life. I love him, John. He understood me, John, in a way you never did. You never understood my wish to prove myself, to become a great scientist; you never understood my will to protect the mistreated creatures of this world, you never understood what it means to be a scientist. We were different, John, even before you changed. And after that, I tried to help you, but you behaved so coldly that I was terrified."

"What about our engagement? What about our daughter?"

"I was so happy when you asked me to marry you, John. But now I realize that you never loved me. Not as much as I loved you. Because if you did, you would have found a way to fight your instincts, your desire to kill. You would have never tried to hurt me."

She is right, John. You are not able to love anyone. You are a monster. But that's who you are, and no one can change you. Nothing thrills you more than killing someone, than watching someone right in the eyes when you kill them. It's a primordial pleasure, John, and you know how it feels. Nothing pleases you more than resurrecting your wounded ego. And Helen and Nikola have messed enough with you. They have to pay, John, and you know it. You know what you have to do, John.

"I am going to ask you one more time, Helen. Do you love me?"

"No." she said coldly.

John drew out his sword and attacked Nikola. Helen tried to protect him, but she was kicked away by Dana, who pulled out her gun and shot her three times right in the chest. But that wasn't going to stop her. Not now. She let her claws grow and transformed into a vampire, then she scratched Dana on the face. Surprised by Helen's power, Dana backed off, but it was too late. Helen attacked her with all the force that she had and knocked her down. Helen realized that she now had the power to kill her, to revenge Ashley, to get paid for all the suffering Dana had put her through. But that wasn't her. Unlike John, she wasn't a killer. She knocked Dana and left her unconscious, then turned to John and Nikola, who were still fighting.

John was constantly teleporting, kicking Nikola from the air, but the Serbian genius wasn't going to give up so easily. He flooded John's body with electricity, causing him to tremble.

"How did you do that? You are not a vampire anymore." asked John.

"You were never good at physics, Johnny. You can easily use a magnetic field to create electricity. But I don't expect you to understand that."

"As I don't expect you to understand why that was a bad idea." He said, cutting him with his sword. "You see, Nikola, I have an electric being inside me. And maybe it wasn't prepared for you and the electricity you could create when you were a vampire, but now it's a different story."

He cut him again with his sword over his chest, causing him to bleed heavily.

"I'm sorry to disappoint you, Nikola, but Helen will be mine after all." John said, and lifted his sword to give Nikola the final strike.

"Over my dead body." Said Helen, thrusting her claws into John's arm. Surprised, he turned to her, leaving Nikola alone for a while.

"So it's between you and me now, isn't it?" he said, hesitating a little.

Now's your chance, John. Kill her. You have the chance to make her pay for all the things she had done to you. She kept your daughter away from you, John. Ashley was your daughter too, but she never told her that. Back at Oxford, she always wanted to control you, she was always your boss, in a century in which most women sat at home and let the men protect them. She wasn't like that, John. And deep down, you always wanted to kill her. Admit it. Those women you killed…they were substitutes, and nothing more. They were weak, John, and so were you. You were never able to kill her. You loved her, but I showed you who she really was. I showed you how women are like, John. They don't deserve to live. Not if they want to take the lead.

John thrust his sword into Helen's chest, causing her to let his arm free. She gasped for air and healed herself, but he kicked her again, knocking her down. Then, he punched her in the stomach, letting his fist go past her skin, so deep inside her that he was almost able to feel her internal organs.

Helen was lying on the floor, almost unconscious, when she saw Nikola lying unconscious besides her. He was bleeding heavily and her doctor instincts told her that every second was crucial. In a second, all her fear and pity for John were replaced by the thought that one of them has to die for the other one to live. And she wasn't going to give up Nikola. Not anymore. Something clicked inside her and she felt her eyes burning of a power she didn't recognize. She held out her hand to John's sword and it flew from his hands, leaving him unarmed.

"How did you do that?" he asked terrified. "It's pure silver, even if you had been magnetic, you wouldn't have been able to do that."

"This happens when you play with nature, John. I don't know what this is, but we'll find out."

She held out her hands at John and knocked him on the wall. Then, she got on her feet and approached him.

"I still think you can be cured, John. Let me help you."

"I DON'T NEED TO BE CURED!" he yelled and got on her feet. "I will kill you."

"Bring it on, Jack."

He grabbed her wrist and teleported with her several times, trying to make her dizzy. When that didn't work, he teleported her atop of a building, and threw her over the edge. Falling, she managed to make John fall too, only by looking at him. Seconds before they would have hit the ground, he grabbed her and teleported back to Nikola's home.

"This telekinetic power of you really pisses me off."

"You should have thought of that before injecting me. You never know what happens if you inject someone with the Source Blood two times."

He kicked her away, making her hit the opposite wall. Then, he grabbed his sword and teleported to her, wanting to cut her head from the air. He disintegrated, but when he reintegrated to the destination, he froze in the air, not being able to move a single molecule of his body. Helen held him like that for a while, then left him fall and hit the ground with great speed. He got up his feet, staggering, still not able to teleport, because she was holding his molecules tied together, and approached her, with his sword lifted. He kicked her, causing her to fall, and then put his sword at her neck.

Now is your chance, John. The only one you really wanted to kill. If you cut her head, she won't be able to survive. You always wanted to take revenge on her; she was too bossy for her own good. She dared to tell you what to do, she dared to tell you that you need to be cured, she dared to fall in love with your rival, she dared to hide your daughter from you…You know what you have to do.

Listening to the voice in his head, John pushed his sword on her neck, causing her to bleed. With death so close to her, Helen realized that she was able to visualize the connections between the molecules in John and his sword. So strong, and yet so easy to break… She concentrated and John's sword started to disintegrate, soon followed by its owner. Before she could realize it, he disappeared in thin air.

She got off her feet and ran to Nikola, who was lying unconscious on the floor.

"Magnus, what the heck happened here?" Will said, storming inside.

"I killed John." She said briefly. "Help me."

Will ran to Nikola and checked his pulse. "I'm sorry, Helen. He's gone."

"Don't you dare say that!" she yelled. "I won't give up on him."

"I'm sorry, Helen, but he lost a lot of blood. I doubt he could have survived."

"I have a plan."

She let Will puzzled and ran to Nikola's laboratory, where she grabbed a syringe and took a blood sample of her. She got to the freezer and took dry ice from it, then got back in a hurry.

"What are you doing?" Will asked.

"My blood will save him. But I have to get rid of the red blood cells, so I could make him a transplant."

"Quick freeze. This may work."

"May being the appropriate word. But I won't give up. I don't want to lose him."

Helped by Will, she managed to carry Nikola in the hospital room she had been in for the last days, and put him on the bed. She injected the blood in his arm and he started to breathe heavily. His wounds began to heal, but it was too slowly, and too late.

"Damn it! Don't you die on me, Nikola." she whispered, crying. She pressed her lips against his, kissing him as if his survival depended on the passion of this final kiss. "I don't want to spend the eternity alone."
