It was late night when Damon went to the boarding house after killing a few more vampires. He was trapped in a house with Enzo and nearly killed him but Wes took Enzo and then the whole Elena thing happened.
He had escaped from Stefan and decided to go to the boarding house but when he got inside everyone was ready to catch him and then Stefan spoke "you shouldn't have escaped Damon…I was going to help you." He said softly but Damon didn't believe him and looked at him coldly "you broke my neck and then vervained me! You expect me to believe that you wanted to help me?!" he snapped at him and sighed.
Katherine was confused that Damon had turned like this,she didn't knew he would lash out like this and then she smirked to herself and walked over to Damon "Damon I can not believe you!" she yelled at him earning a surprised look from Stefan.
Damon looked at her confused "Elena wh-what are you talking about?" he asked confused and looked at her. She sighed and looked at Damon and acted like she was hurt "I tried to help you fight it…I wanted you to resist it! But you didn't do that for love?! You rather kill the love of your life than die from hunger and blood thirst?!" she yelled the last part but she got confused when Damon got serious and not hurt or confused.
Damon growled and his veins and fangs became visible and he hissed at her "you were the idiot one that took the glass and slit your hand! I wasn't in the need of vampire blood before I saw your blood! So it was kinda your fault not mine! And you think I was too lost in the feeling of your blood that I didn't notice that you mentioned Stefan to kill me?!" he yelled at her angrily and then looked at Stefan.
Stefan sighed and looked at Elena\Katherine "Elena did that cause you weren't able to stop until she was dead. But none of you are dead now! Elena is alive and so are you Damon."he said softly and Katherine rolled her eyes "he nearly killed my brother to find Wes! He killed my new friend Aaron!" she yelled and vampire speeded to Damon and pushed him against the wall and stabbed him near his heart with a stake and then Damon gasped and his eyes widened "you…really want to…kill me?" he whispered weakly and heartbroken.
Katherine looked at him and smirked "why would I want a heartless moster like YOU alive and well?!" she snapped and then snapped Damons neck and removed the stake from his chest and throwed it away and then looked at Stefan "take him down the basement and lock him up" she said and then went upstairs as she smirked evily to herself and giggled a little.
