"Draco" said Dumbledore, "we can help you."
And when that was said Draco went into a flash back of two year ago.
"Potter," Draco said "glad to see you're okay now."
"Shut Up, Malfoy" she screamed at him and went in to her room and locked the door.
He could hear he crying and I went to see what was wrong. When he got to her door he found it locked and her screaming and crying.
"Kiersten open up."
He said but he didn't think she could hear him over her screaming. Then he heard he scream at someone who was on the balcony.
"Go away I don't want to see you." She shouted and was sill crying. Then she stopped crying and shouted a spell.
"Crucio" and you could hear the boy screams of pain and he knew it went too far.
He then unlocked her door with his wand and came in. He grabbed her and she dropped her wand and cried into his chest. He then led her out of her room, down the stairs and on to the couch. When they sat down she sat on the far end of the couch, not letting him touch her, and she started crying again.
"Kiersten, why did you do that? Tell me and I could help you through this." he said and she stopped crying and looked up at him.
"I don't want your help. Don't you see, I had to do that. I had to hurt him, or else he was going to keep hurting me" she said crying again.
Then Draco came back to the situation at hand and looked at the old man standing before him. He knew Dumbledore knew what was going to happen and Dumbledore was the only professor who knew about him and Kiersten. Draco felt bad about what was going to happen and wished he didn't have to do what he was forced to do. He knew he would have to tell Kiersten about this and what he said and did, but little did he know she was watching with harry under his invisibility cloak.
"I don't want your help. Don't you see, I have to do this. I have to kill you or he's going to kill me." He said and he thought he heard a muffled cry from the corner of the room.
"Avada Kadava" Draco said and a jet of green light came from his wand and hit Dumbledore and he fell from the tower window. With that he went to the window and saw Dumbledore land on the ground and he heard sobs from the corner but didn't see any body.
"Who's there?" he asked, raising his wand, but he knew those sobs all too well and knew Kiersten was some were in the room.
"Petrificus totalus" he heard Kierstens voice scream and he couldn't move.
Then Kiersten and Harry showed themselves and Kiersten had tears streaming down her face and she started screaming at him and hitting him but he couldn't talk or defend himself.
"How could you," she screamed while hitting him "I trusted you. I loved you and killed him and used words I said as the last word Dumbledore ever heard."
Harry had to pull his sister off of Draco and hold her back and tuck the hex off of Draco and allowed him to stand up. Then Draco cast the same spell on Kiersten to get her to stop screaming and to stop thrashing. He then walked up to her and put his hand on her face and wiped the tears away from her eyes. Through all of this harry was watched the murderer of the headmaster talk to his sister.
"Kiersten," he said "I'm sorry I didn't tell you what I had to do. I'm sorry I used your words as the last word Dumbledore would ever hear but you have to know he was happy to have your word as the last word he heard. He knew they were your words. And I'm sorry you had to see that I didn't know you were here. I'm sorry" he said and kissed her.
"Okay Malfoy I think you made your point now stop kissing my sister now, but don't take that hex off her I think she will start freaking out if you do." Said harry interrupting Draco and his sister. Draco laughed and said.
"Hay I think I'll take her to our dorm and talk alone I don't want her to have to see him down there." And he pointed toward the window. Harry nodded and Draco picked up Kiersten and tuck her down to their dorm. When he got there he put her down and tuck the hex off of her and she stared sobbing and every time Draco touched her she would scream like he had hurt her. Eventual she stopped crying and stud up.
"How dare you touch me. How dare you kiss me and pick me up after what you did. I don't want to be touched by a filthy death eater." She screamed at Draco and grabbed his left sleeve and pulled it up to his elbow. She then saw the dark mark on his forearm and pulled away and would not face him.
"How long?" she asked "how long have you had the mark and the mission?" she turned to face him and she had tears all down her face and then turned away.
"Since July and August." He said stepping toward her and grabbed her arm and turned her around and put his hand on her face and his forehead on hers. "I'm sorry." And he pressed his lips to hers. She then mover her hand to his hair and started kissing him back. He moved his hand to her waist and they stayed like that snogging for a while and she then fell to the floor because her knees gave out.
He laughed and picked her up and carried her up to her room and put her on her bed and they both fell asleep.
