Chapter 2, Explanations. (A:N in this story Dumbledore is still alive.)
"Minerva, help me find Severus..the fake one, and bring him to my office." Dumbledore shouted over all the noise."Harry come with me". They walked up to the gargoyle, Dumbledore spoke the the password and they stood on the step which took them up to the door. Dumbledore opened it and told him to sit down and wait for them to come.
"Here he is, I had to subdue him because he was trying to run!" Professor McGonagall exclaimed. Dumbledore raised his wand and a Petronus came out. The phoenix went out of the door. They waited for a few minutes and then the heads of houses came in.
"I think you need to see this" Dumbledore said as he took a vial of what looked to be virtasirum, opened the fake Snapes mouth, and poured it in. Then he pointed his wand at his chest and said, Enervate. His eyes opened instantly.
Dumbledore said "Why are you pretending to be Professor Snape?"
He answered "Because Snape had to use polyjuice potion to look like the Dark Lord."
"Why was snape using polyjuice potion to look like voldemort?" Harry asked.
"The Dark Lord was still too weak to come and try to defeat you, so he asked his spy, Severus Snape to pretend to be him, and he needed someone to be Snape. He showed me the ingredients for all the potions the students would be making over the year and how they should look."
"We still need to find out who he is, I say we should get the potion that will put him back to normal" Professor McGonagall decided.
"I have that on me as well, Minerva" Dumbledore said, as he pulled another vial out of his cloak, and poured it down in his mouth. They watched as his greasy black hair turned into silver blonde hair, and Severus Snapes features turned into the features of Draco Malfoy.
The heads of houses looked on in horror and Dumbledore shook his head In disappointment. Harry was furious, for one the real Voldemort was still out there after all this work and two his worst enemy was his teacher?
