Serena Willow Lupin

Patronus charm

Dementors
These where the only creature who could do this, luckily I can do a patronus charm, so I am safe and so are Harry, Ron and Hermione thanks to me and dad. As I wondered if it was a different creature the compartment door, slid open with a dead looking hand clenched around the door. It's cloak hung all around it, even covering its face as it floated through the door. It floated over to Harry who became very white, before the dementor could suck the happiness out of Harry, I jumped to my feet shouting " Expecto Patronum!" a I said the words a dog like wolf cane out of my wand fitting the dementor, and I turned around to see dad doing the same, his patronus the same as mine. The dementor floated away and the lights came on and a warm feeling came though the train. I looked at Harry who feel to the floor. 5 minutes went by an harry started to wake up. Dad handed him some chocolate.
"I'm just going to talk to the driver. eat the chocolate you will fill better" dad said before going though the compartment door and heading up the train.
"You better it the chocolate harry, it will make you fill loads better, trust me" I said giving him a small smile and he took a bite of the chocolate. "better"
"Yer thanks" said harry smiling at me.
"What was that thing...... and who screamed" said harry before talking another bite of the chocolate
"They are dementors who work in Azkaban. They were properly searching the train for Sirius Black" I said before anyone could talk.
"But....who was screaming???" replied harry. "no one was screaming harry" said hermione who looked panicked.
"Don't worry Harry that is one o the side affects of the dementors, they make you remember your worst memory, so yours would be someone screaming, we are all different"
I said smiling to give him some confidence back.
10 minutes past by just in silence. Dad came back and sat down
"Very well done Serena, very well done.... are you ok Harry, do you fill better" Said dad looking at harry.
"Yes thankyou, a lot better" replied harry. There became a loud whistle. I grabbed my trunk and Shadow and walked out of the compartment and off the train to a platform. When I got off I asked dad where to go, he told me to follow harry and he will see me in a minute. I followed Harry.
