"Felicity gave me these for each of you," Oliver said. "Barry and I have them in our suit." Clark, Kara, Mon-El and I put them into our ears and in an instance I could hear Felicity's voice.

"Move out," I ordered.

Clark reached for my hand, "Stay safe," he whispered. I nodded, I leant up and kissed him softly, "I mean it if you need me."

"I know," I whispered. "Hey Clark." He looked at me, "I'm moving back to metropolis with you." He smiled, "I love you Clark."

He flew up and I looked at Catalina, "that will be a combination that nobody has seen before," she smiled. "He cares deeply."

"Are you ready to face your sister?" She shook her head, I walked forward and lifted my hands freezing the guards, the good part about them being human is I could slip by them without harming them. I ran forward towards the house and swung open the door, I was quick to duck as a fireball headed my way. "Fireball!" I called and it landed in my hand I threw it back to them, it wasn't long before I was getting more and more hit my way I was dangerously outnumbered. As I looked at Catalina for helped, she had gone. "Fuck."

I pulled out the athame, I went running out the demon stabbing him, he burst into flames, I felt a fireball hit me and I fell down, I lifted my hands up blowing them up. I stood up and blew up another demon.

"Libby!" Clark shouted. I turned around just in time to be pushed onto the floor as the fireball hit Clark. He pulled me up quickly, "where did that other witch go?!"

"I don't know," I said. I tried to freeze the demons, it broke through them. I thought of the fire and it began shooting out my hand, I aimed it at the demons and they began to vanquish, I could feel myself getting weaker the more I was using it.

"Libby stop!" Clark said grabbing my hand. I fell forward a little bit, "stop using your fire. It's taking to much strength, you are not an unlimited power source. You will burn out." I nodded, I knew that but I had to get to my sister. Clark's laser eyes came out as he destroyed the demons in our path. "Do you know where she is?"

"Felicity any idea?" I asked.

There was silence and I made sure the coast was clear for demons, "the attic, there's a lot of heat signatures up there, but it's heavily guarded."

"Alright thanks," I said with a nod. We made our way up the stairs taking each step slowly, I saw a demon passed and threw my hands up blowing him into pieces.

"Nice shot," Clark praised.

I had plenty of practice that was for sure, we went to the top of the landing, and I saw a demon coming towards me and I kicked him, I slammed the athame into his chest and he vanquished in front of me. I looked to see Clark fighting a few demons, I pulled out the potions and threw them in his direction. The demons burst into flames and Clark made his way towards me, we ran up the next stairs and were led to the attic. I shoved open the door and threw my hands up blowing up the demons. After a few moments they shimmered out the room, Kelly was in the room tied to a chair. Clark went to get her and I grabbed him stopping back.

"What?" Clark asked confused.

"Too easy," I said shaking my head. "Way too easy." He stared at me. "Something feels off, I can't explain it to you." Kelly was knocked out in the chair but it still felt wrong, like it was a trap. I went to step forward, nothing happened. I took another step and I felt Clark grab my arm. "What?"

"You're right it's a trap," he said. "Something is off." I grabbed the potion and pulled it out my bag, "you're going to throw it at her?"

I nodded, I threw the potion and she burst into flames, as she did her face changed and in her place was a demon. "So where's my sister?" I asked, as he vanquished.

"No heat signatures from what I can tell," Felicity said.

I grabbed an athame, "power of the witches rise, course unseen across the skies, come to us who call you near, come to us and settle here." I pricked my finger, "blood to blood, I summon thee, blood to blood return to me."

White swirls appeared in front of me and I came face to face with my sister Kelly, she fell to the ground and I grabbed her arm. "Are you okay?" I asked.

"No," she coughed. "She has her sister. Basement." I pulled her off the floor and she gripped onto me tightly. "They're using magic against each other, you know what happens with that."

"If you could do that, why didn't we do it in the first place?" I heard Felicity ask.

"It doesn't get rid of the problem," I said. "Like I'm sure both Oliver and Barry have had we needed a final battle, this is it."

"Humans are cleared out," Barry spoke into the coms.

"Leave," I said. "All of you, thank you for the help but you don't need to be in danger for this."

"Are you sure Liberty?" Oliver asked.

"Yeah, you too Kara and Mon-El," I said. I pulled out the coms and nodded for Clark to do the same, he did and I pressed my hand to his face. "I need you to go to," I whispered.

He frowned and shook his head straight away. "I'm not leaving you Libby, I don't want to leave you," he said.

"I know," I said. "But I also know if you are here I'll be focused on you and not the black Witch. I need to be able to focus and you take my mind into lala land." He smiled a little, but I caught the sadness in his eyes. "This needs to be a fight between us and her, not you." I leant up and kissed him, "I love you so much."

"I love you too Libby," he said softly. He kissed me back and stroked my face, "come back to me."

"We will see each other again Clark, I promise," I said reusing his words from the night he left. He smiled. "Go."

He flew out the attic and Kelly looked at me confused, "why did you do that? Surely we can use them?" Kelly asked.

"I'm not sure I'm coming out alive," I whispered.

She stared at me, "don't say that, why on earth would you think that?" She asked outraged.

"A feeling I have," I whispered. "Someone isn't coming out of here alive. I'm hoping it's the Black Witch." I shook my head, I was burning out and I knew it. "Just Kelly, whatever happens orb out."

"Not without you," she said. "I will not leave you." She stood in front of me and grabbed both of my hands squeezing it. "Our love, our sisterhood, our bond is our greatest power." It sounded corny but it was true.

I slipped the com back into my ear and looked at Kelly, "has everyone gone?" I asked.

"Yeah," I heard them say.

I walked out the basement and Kelly followed me, we made our way down the two flights of stairs to get to the basement. I stood at the basement door and shivered a little, they always creeped me out. Kelly shook her head amused and I elbowed her slightly, "it's not funny," I muttered. "Basements always creeped me out." I heard yelling and creeped down the stairs, Kelly and I sat on the step as we saw Catalina and Katarina arguing with each other.

"Stop making excuses!" Catalina yelled. "You smeared my name, my story! You smeared it and then stole it."

"You could have just joined me," Katarina said. "We would have been powerful, we still could have been." She smiled and stroked her sister's cheek. "But no. You wanted love." She slapped her across the face. I will destroy the ultimate power for I am the ultimate power."

"You can't, you'll end our blood line in the process," Catalina said. "You said you wanted our line to grow and it has, our family line is powerful witches."

"I'm going to kill them and you can't stop me Lina," she snapped angrily. She reached her hand up and I felt us flying across the room I slammed against the wall and I groaned. She lifted her hand and froze Kelly, but it wasn't like my freeze. She was literally frozen, "so predictable," she spat. "Sisters. She will be your downfall." I reached for my potions and went to throw them before I could they smashed in my hands. "Can't defeat me without your potion can you?!" I lifted up my hand and thought of the fire and it came shooting out my hand, I crawled up off the floor, it did nothing to her. No burning it was like she was under some kind of protection spell but I had never known one to work.

She lifted her hand and the fire disappeared, "What are you exactly?"

"I'm the best witch there ever was," she laughed. "Not even the pathetic ultimate power can harm me." I stood up and glared at her hatefully. I was going to destroy her. I noticed she was very particular protective of one thing and it was a little book. I aimed my fire at it and it began to burn. I concentrated, my head was burning it felt like I was on fire. I moved it onto her and concentrated every last bit of my energy onto vanquishing her. I was loosing control, fire appeared from my other hand and I smiled.

"Now it's your time to die," I smiled sweetly. I put all the force I had into making her die. I reached for the potion and threw it at her. I turned as I heard a scream, I looked to see Kelly unfrozen and with her force field round.

"You're on fire!" She yelled.

I looked down to see I was in fact on fire. But it wasn't burning me. I screamed as I felt myself getting hotter and hotter. I felt myself going dizzy. "It doesn't hurt."

"You're burning out" Kelly yelled. "Quite literally." I ignored my sister and threw my hands up blowing her up, I switched back to the fire and she burst into flames. I let out a scream as I let every bit of my power destroy her. I felt myself flying back as something exploded as I hit something I felt myself entering darkness.
