Harry got up from his seat and ran out of the great hall towards were his sister had run, right out of the large oak doors that opened to the outside. He watched her run as far as she could the fall down on her back and lay there staring up at the sky. Harry ran to her and sat down next to where she had fallen on her back.
"Are you okay Lindsay?"
"Yeah I'm fine Harry, don't you worry about me."
"I can't really help it the way you ran out like that. Why did you do that anyhow?"
"Harry some things you should know, you don't know and I'm really not the person to tell you."
"But, you're my sister!"
"I know that! But I still shouldn't be the person that tells you these things Harry! Oh if only he were still alive."
"Who?"
"Our father, genius."
"So how are you my sister again?"
"I'm your half sister. Your mother is Lily Evans Potter. Mine was Krista Rowben Barnes."
"Is your mother still alive?"
"No." she answered shortly looking away from him.
"How did she, you know?"
"A death eater. Bartholomew Aderdale, that's how I got my scar, yours is more famous that is because you took out Voldemort with yours. I just got a follower with mine who wasn't smart enough. People tend to think we got ours the same way, but we didn't. Maybe its because we are both potters or something."
"Some one told me you lived with your mum though."
"I let people believe that because it's easier than the truth."
"What is the truth?"
"Well," she began looking kind of skeptical. "After my mum died I didn't have anyone else left so I was either to live with my cousin or with my mothers best friend. Remus Lupin.."
Harry stared at her for a second. So Professor R. Lupin was the person she lived with?
"He's been my only friend basically all my life until I attended Hogwarts when I was eleven and met Morgan and Nikole. Then a lot of bad things started happening in my life and I had to take it into my own hands which resulted in three years of me not being able to come back to Hogwarts not just for my safety but for yours as well."
"Why would I be in any danger?"
"Because Harry, I'm just not a safe person to be around."
"You're my sister! Of course you're safe to be around!"
"Harry, just be careful."
"You should be careful around me! I am the one Voldemorts after not you!"
She shifted nervously were she sat and turned to him completely "Harry, you need to understand that Voldemort is only as strong as his followers, without them he would be nothing."
Harry sat there looking confused for a minute then she stood up and offered her hand for him to stand too. He rose and they walked back to the school in silence.

"Potter, may I have a word with you?" Professor Snape practically hissed at the end of the lesson. "Your sister? Would you give her this note, I saw her this morning but I was very involved in something else." He handed Harry a note that was folded in half.
He left the dungeons and headed for the Great Hall for dinner and to meet up with Lindsay and give her the note Snape had told him to give to her. When he got there he saw her sitting with Morgan and Nikole just staring at her plate while Morgan rubbed her back and Nikole whispered something to her. He walked over to her and handed her the note.
"It's from Professor Snape."
"I see that, thanks Harry."
"No problem."
He walked off to sit with Ron and Hermione who were fighting again about something stupid.
"Ron you know Harry's not allowed-"
"What? I'm not allowed what?"
"Well remember you missed the first Hogsmeade weekend?"
"Yeah, not hard to forget."
"Well Fred and George have an idea!"
"No Ron!" Hermione yelled.
"Go on!" Harry said loudly ignoring Hermione.
"They want to show you in the common room! It's this map of Hogwarts, but I don't really know that much. Come on lets go! They will tell you when we get there!"
Harry finished his dinner quickly then they rushed up to Gryffindor Tower where Fred and George were already waiting. There were only a few other people in the common room but they looked uninterested in what was going on between them.
"Harry! Good to see you old boy! Now lets get down to business. This," Fred said softly pulling out apiece of old looking parchment. "Is the Marauders Map. I solemnly swear I am up to no good!" he whispered and taped the map with his wand. A map of the entire school showed up instantly. "Now Harry there are a number of different passages out of the school and to Hogsmeade. This one -Er- Filch knows about. That one was caved in. The others are good though. Use it well! Now I have other things to be getting to!" they both jumped up and left walking towards some first years that looked like they felt very important.
"Harry, you cant use that! Its for your own safety you heard McGonagall!"
"Yes I did hear her Hermione."
"But--"
There was a loud crashing noise that came from right outside the portrait hole and someone basically screamed the password then four girls came rushing in and slamming the portrait behind them. It was Lindsay, Morgan, Nikole and some girl he didn't recognize. They were breathing very hard as if they had been running a long distance and Lindsay looked as if she had tears in her eyes. They didn't even stop they all ran right up the spiral staircase to the girl's dormitories.
"Wha?" Harry said stupidly.

The day of the next Hogsmeade weekend Harry was walking carefully not to make to much noise towards the secret way out. There was much arguing with Hermione but in the end Lindsay talked to her about it and calmed her down. They were actually forming a friendship since both Morgan and Nikole had boyfriends now, Morgan was with the Quidditch Captain Oliver Wood and Nikole was with some guy in Ravenclaw. Just as harry was walking past Lupin's door he heard shouting and a girl crying. He walked faster till he was right in front of the door and pressed himself up against the wall next to the door to listen to the conversation.
"SEVERUS YOU KNOW WHAT COULD HAPPEN IF ANYONE FROM THE DARK SIDE FINDS OUT!"
"It's the only way Remus!"
"There has got to be another way!" he heard Professor Lupin cry helplessly.
"There isn't Remus." The cold voice he recognized as Professor Snape's voice.
"It's more up to Lindsay than anyone in this room." Professor McGonagall's voice cut into the conversation.
"I still don't think this is right but it really is up to Lindsay, but you must choose wisely and we will follow your lead." Dumbledores voice chimed in.
The crying has mostly stopped by now to sniffles and a soft voice entered the conversation. "I'm ready. This is really the only way da- Professor."
"Are you sure?" Lupin said seriously.
"I'm quite sure. I'm the only one that's not risking anything. You all are very important to fighting the dark side and Harry is far too important to the wizarding world. He to will be great." Lindsay said in a soft voice but he knew she didn't make decisions without thinking about it for a very long time. A thick silence fell over the room and Harry heard someone slam their fist on something. Harry turned around and headed off before he had to hear anymore.
Once he was in Hogsmeade with Hermione and Ron they went into Three Broomsticks where he spotted Lindsay sitting by herself looking as if she had just cried for hours.
"Hermione, go over there and tell Lindsay to come join us!"
"Okay."
She walked over to Lindsay who looked shocked that someone was talking to her and she stood and followed Hermione to the table. Lindsay sat down sort of numbly then looked at where Harry was sitting very seriously, how she knew he was there he wasn't sure of.
"Harry, you must understand I know we have only just met but I have to go away for a while. I know this isn't a good time at all for me to leave, but I must. Sometimes you have to do things you don't want to do because its good for other people. You understand? Don't you Harry?"
"I think so. But, where are you going?"
"Far away Harry, where the evil dwells. I will write to you as much as I possibly can and u know I wouldn't say something if I didn't mean it."
"I know." Harry replied feeling very depressed.
"Harry don't sound so upset. How 'bout I promise I'll be back?"
"You cant break a promise!"
"I wouldn't break it for anything in the world Harry Potter. I promise I'll be back."
