A few seconds later they were in the astronomy Tower.

"We have to get you to the hospital wing sir. To Madam Pomfrey." Harry said tired.

Tracey grabbed his hand and shut her eyes tightly. She had given him enough energy to be able to stand up properly.

"No, Severus, get Severus." Dumbledore said.

"But sir." Tracey started.

"Harry do what I say, trust me." he said interrupting her.

So he headed to the stairs.

When he was on his way there he heard Dumbledore say something.

"Good evening Draco."

"What is Potter doing here?" Malfoy said.

"She was just out here and I was looking for her. I found her up here. Have you always been to yourself Draco? Draco, you are assassin."

"How do you know what I am? I've done things that shock you."

"Oh, like cursing Katie Bell and hoping that in return she would bear a cursed necklace to me? Like replacing a bottle of mead with one lace with poison. Forgive me, Draco, I cannot help feel these actions are so weak that your... heart can't really have been in." Dumbledore said.

Tracey stood there quietly.

"He trust me. I was chosen!" Malfoy said and took out his mark.

"I shall make it easy for you." Dumbledore said.

"Expelliarmus!"

Then Dumbledore's wand fell out of his hand.

"Very good, very good. You're not alone. There are others. How?"

"The vanishing Cabinet in the Room of Requirements. I've been mending it."

"I'm guessing it has a sister.

A twin.

In Borgin and Burkes. They form a passage." Malfoy said.

"Ingenious. Draco, years ago, I knew a boy who made all the wrong choices. Please let me

help you."

"I don't want your help. Don't you understand? I have to do this. I have to kill you. Or he's gonna kill me." he said scared.

"Well look who we have here. Well done Draco." Bellatrix said.

Harry pointed his wand but then saw Snape.

He put a finger on his lips telling him to stay quiet.

So he looked back up.

"Good evening, Bellatrix. I think introductions aren't over, don't you?" Dumbledore said.

"Love to, Albus, but I'm afraid we're on a bit of tight schedule. Do it!" she said.

"He doesn't have the stomach. Just like his father. Let me finish him in my own way." someone else said.

"No, the Dark Lord was clear the boy has to do it. This is your moment, Draco. Do it! Go on, Draco, now!" Bellatrix said.

"No." Snape said.

"Severus. Please..." Dumbledore said.

He took out his wand and said,

"Avada Kedavra."

Harry and Tracey stood there in shock.

Then they came back and started running after Snape.

When they got there Bellatrix was starting Hagrid's hut on fire.

"Snape!" Harry yelled.

He turned around and saw Harry and Tracey running to him.

"We trusted you!" Tracey yelled after.

"Go on!" Snape said to Bellatrix.

"Incarcerous!" Harry yelled.

"Fight back, you coward! Fight back!" Tracey yelled.

Then Bellatrix aimed a curse at Harry.

"No, he belongs to the Dark Lord. And everyone knows how protective he is to the other one." Snape said.

She frowned and turned around.

"Sectumsempra!" Harry yelled.

Snape just pushed it back like before.

He was about to use legilimancy on Harry but then remembered he was a strong occlumence. So he looked at Tracey but she was an occlumence to.

'Blast! I taught him that when he was eight! He must have taught his sister last year.' he thought.

He decided to just let it slide.

"You dare use my own spells against me?"

Harry sat up and Tracey stood there in shock.

"Yes Potters, I'm the halfblood Prince."

When Snape was gone Harry and Tracey walked to Dumbledore's body.

When they got there they sat down next to him and started crying a little. Tracey was on Harry's shoulder and then Ginny came over and grabbed the other side.

Dumbledore raised her wand and some light went off. Everyone else did the same thing.
