Through thick and thin (Katelyn Hollow X Severus Snape) (HP fanfic)

Chapter 24 Katelyn POV

I was still shaking after I put the gun down. Then Severus sat down beside me and wrapped an arm around me.
"So why are you here", I asked my sister.
"He is back", she said plainly. Horror over came my face.
"Oh please tell me you are kidding", I said.
"I am not", she said, "I came to warn you."
"If he finds...we are doomed", I said.
"What is going on", Severus asked.
"Ok so you know my older brother that you have seen", I asked.
"Yeah", he said.
   "His name is Josh", I said, "he has a twin brother that also follows you-know-who. His twin, Benjamin, is back. Benjamin has been hunting Samantha and Josh has been hunting me down and Benjamin is back in Britain. He followed Samantha out of Britain. With the two of them here I am doomed and so is Samantha." My hair went back to white now and Samantha's went to a light blue.

I paced around the room. Then it came to me.
"Samantha, come with me", I said dragging he out.
"Where are we going", she asked.
"You are going to be a student at Hogwarts", I said.
"WHAT", she asked, "I can't do that...our brothers are running around hunting us down...I am socially awkward...we might be found out...SO MANY THINGS COULD GO WRONG!"
"It is not up for discussion", I said dragging her to Dumbledore's office. I opened the door.

Time skip: two hours later

It was official my twin was a student at Hogwarts. She was A Hufflepuff. She grabbed her stuff and I showed her to her room. I walked down the hall and out of the corner of my eye I saw Benjamin talking to a professor.
   "Well if you see either of them please let me know", he said. I gasped and hid. He walked off and I emerged from my hiding spot. I ran back to Samantha.
   "Ok so I saw Ben talking to a professor...he doesn't know we changed our hair", I said quickly.
   "So Benjamin thinks we are here", Samantha asked.
   "Apparently", I said, "Ben wants you for personal reasons but a lot of death eaters are after me because of orders from you-know-who."
   "Ok stay safe", Samantha said. I ran all the way to the dungeons and rushed into Severus's office because the door was open. I shut the door and saw a very confused Dumbledore and Severus.
   "What happened", Dumbledore asked. I held up my pointer finger to say give me a minute. I put my back against the wall and slid down to the floor looking up and catching my breath.
   "Well", Severus asked. The tips of my hair started to go brown.
   "Oh no", I said when I noticed. Then Samantha burst in. Her hair was doing the same thing.
   "Katelyn", she said.
   "I know", I said, "we can't step out of this room now..."
   "Why", Severus asked.
   "Ben and Josh are using a special spell to reveal us...meaning we will have our brown hair and I won't need Invisalign...Samantha will need glasses and so will I", I said in a rush. Samantha looked at me in worry.
   "We will also have to do something else", Samantha said.
   "What", Dumbledore asked.
   "That is for us to know and you two to figure out", I said, "do you have your wand, Samantha?"
   "Yeah", she said.
   "Good", I said, "let's hope this works." We walked out and ran into Benjamin.
   "Hey Josh, I found them", he called.
   "Can we take this outside", I asked.
   "Sure", Josh said as they dragged us outside. I had my wand in my hand under the sleeve of the school robes and the same for Samantha. Then Samantha took the first shot. The two boys dropped us and grabbed their wands. We shot several spells at each other. I looked at Samantha and she nodded. Then Dumbledore and Severus came running out. I pointed my wand at them and said something that nobody could make out and I was lifted into the air and a bright light shown. My brothers were gone for good. Then the light faded and I drifted to the ground unconscious.
   "Katelyn", Severus exclaimed. He ran over and picked me up. My hair was white again and Samantha's was blue. Samantha stood there trying to process what happened.
