*This Takes Place In First And Second Year* Storyline: Harry and Ron meet a girl on the train named Guinevere. Who is the descendant of Merlin. Of course, she would be sorted into Gryffindor, right?

The One Shot!

Harry's POV

Ron and I were sitting in a compartment on the train. The train was about to move when someone knocked on the door of the cabin. Curious, Ron opened the door. A girl with dark brown hair and brilliant blue eyes.

"Hi, can I sit in your compartment with you? The entire train is full." She asked. Ron looked at me and I nodded to her

"Sure" He said. She sat down next to the door and Harry half expected her to ask about his scar, but she stayed silent.

"So, what's your name?" Ron asked

"Guinevere thought I go by Gwen, your's?" She answered simply.

"Are you Merlin's granddaughter? I heard he had a granddaughter named Guinevere." Ron blurted

"yes," She mumbled.

"Oh that's so cool! I bet you're going to get sorted into Gryffindor!" Ron kept talking, clearly not getting the message that she didn't want to talk. about it.

"Yeah..." She trailed off

*Rest of the train ride takes place as in the book, with the addition of Gwen, but she's sleeping, now it's the sorting*

We were in a dark room with stone walls where Professor McGonagal told us to wait before we were sorted.

"Come on first years, follow me to be sorted into your houses..." She said to us. I caught a glimpse of Gwen, she was nervously moving her hands and had a small smile on her lips. The Professor lead us into the dazling Great Hall. She instructed us to line up and we did so.

"Weasly, Ronald!" She shouted, he walked up to the stool and sat. The hat barely touched his head before declaring him Gryffindor.

Professor McGonagall continued to yell first year's names until she reached one which made her inhale a breath.

"Wyllt, Guinevere!" She declared. The room erupted into whispers. I assumed they all knew who Gwen was.

Gwen sat on the stool and the hat flopped over her head. Everyone was silent to see what the Hat would choose.

After a long minute, the sorting hat gave her decision. "Um Gry-Slytherin!" The sorting hat stuttered out. The room was in a state of silent shock.

Gwen however, wasn't. She lifted the hat off her head and dropped it back on the stool. When she turned back to the crowd she wore a smug smile that chilled me to the bone. She strutted over to the Slytherin table where the Slytherins finally came back to reality. They cheered loudly and welcomed the newest Slytherin.

The other houses still remained silent. The Gryffindors looked the most shocked.

How could a descendant of Merlin become a snake?

She would become very dangerous, and very powerful. Harry didn't know much, but he knew that.
