Chapter 3: The angels

"Good morning class!"
The Doctor happily said. He observed the class and didn't notice some of the girls looking at him dreamily.
"So, Defense against the dark arts, eh? I'm professor Smith, and this is my assistant, Mistress Tyler."
The class looked unenthusiastic.
"Well, the previous professor ran away overnight and they hired me in her place."
The class looked bored now.
"Okay,so can somebody tell me what a Weeping Angel is?"
Everyone looked at Hermione for a answer, but she looked as perplexed as the rest of the class.
"Well, what a gap in your education! Okay, so, a Weeping Angel is a stone angel that can transport a person to another time and place forever. Which is why I always say, Don't Blink."
He had the class intrigued now.
"Sir?" Hermione raised her hand. "Why do the Angels do this?"
"They feast on people's potential in life. So, take this for example. Someone gets touched by a angel. Their timeline will be erased from the time they were born, to the time they die. But you are taken at your current age, to a new time and place. You live the rest of your life there and you can't go back."
The bell rang and the class groaned. This was the one class that just got interesting.
The students cleaned up their areas and left the classroom. Rose was staring at the lake.
"Rose? Are you okay?" The Doctor asked.
"Yes, but look at the lake."
The Doctor looked out to the lake. It was shining brightly, even in broad daylight.
"The lake shouldn't be doing that." The Doctor said.
"What's wrong with it? Do you know?"
"Nope. I think I will go scan it and test it at lunch. I'll tell you the results later."

Harry and Hermione walked down the stairs on their way to Care of magical creatures with Hagrid.
"There's something strange about Professor Smith and Mistress Tyler. Professor Smith doesn't seem human." Harry said.
"Well, maybe he is a bit peculiar. But I loved his lesson today." Hermione responded.
Harry didn't respond. He didn't say a word until lunch, when Hermione asked about Ron to Ginny.
"I haven't seen him today. Harry, do you think he dissapeered like Autumn?" Ginny asked him.
"I'm not even sure how Autumn dissapeered." Harry responded.
"I think it is the lake." Ginny said. "I've heard that victims were walking down the bank of the lake, and then they dissapeered."
"What about Ron though? He was in bed when he went missing." Harry said.
"Maybe he snuck down." Hermione said.
"Why would he sneak down at night?" Ginny asked.
"Harry, did you and Ron go down to the lake the night he dissapeered?" Hermione asked.
"No." Harry said.
"Well, I guess we can talk later. I have to get to class." Hermione said as she grabbed her schoolbag and walked off.

Meanwhile, by the lake

The Doctor scanned the lake with his sonic screwdriver.
"Strange readings." The Doctor mumbled.
"Demons?"
"No. I killed them all."
He pulled out a test tube. He quickly got a sample of the water and capped it. He ran back to the castle.
He got up to his classroom to find Rose, sipping pumpkin juice and eating some soup in a cup.
"What did you find?" She asked.
"Well, my sonic screwdriver was getting some strange readings, so I thought I would just test some water out." He responded.
He held the tube up to the light. It was muggy and looked black. But when he brought it down from the light, it went back to shiny.
"I'll have the TARDIS analyze it." The Doctor said as he walked off to the TARDIS.

A few hours later

The Doctor finished teaching his last class of the day and, once they walked out, the Doctor made a mad dash to the TARDIS.
"Rose! The testing is finished."
Rose came into the TARDIS and stood next to the Doctor.
"What are the results?" Rose asked.
The Doctor's face went dark. "Lake Demons."

A/N: As far as I know, I made up "Lake Demons." Reviews make my day brighter!
