A Harry Potter Fanfiction

It Started With a Bet

4

Troy Troublefield was a seventh year Ravenclaw. He was a chaser on the Quidditch team and was the ex-boyfriend of one Arena Blackwood. He currently sat at his house table enjoying his lunch. Well he was until a certain Gryffindor group came over.

"Oi! Troublefield." Sirius said causing the Ravenclaw to turn away from his lunch and face the four Gryffindors.

"Yes?" he said in his deep voice.

"You went out with Arena right?" James asked bluntly.

"Yeah, what about it?"

"Well my friend here wants to take her to Hogsmeade. Problem is she won't give him the time of day." James said, "We were wondering how you got her to go out with you." then Troy started to laugh. "Let me get this straight. Sirius Black wants to go out with Arena Blackwood. No offense to Arena but...why?"

"Just tell us!" Sirius said getting agitated at the boy.

"Fine, fine. I'll tell you." Troy sighed, "Arena and I used to study together. I know she isn't pretty but she is fun to hang out with. We dated for a month before her cousin found out a threatened to beat me up if I didn't dump her." his head sunk low. "I didn't get a chance however because Arena found out and dumped me before I got the chance."

"Why would her cousin care if she dated?" Remus spoke up.

"I promised Arena I would never tell anyone. Sorry." Troy said before turning back to his friends and lunch. The Marauders stood there for a second before walking away.

"So for some reaon her cousin doesn't want her to date. And we found out she's fun to be with." James said.

"I got a plan!" Sirius suddenly shouted causing several people to look at him.

"What is is?" James said, just as loudly as Sirius.

"I get her to either study with me or tutor me." he said causing Remus to sigh. "You never study." he said

"Your right! But I could say I need a tutor." Sirius said, "I mean think, NEWTs are coming up and so is the auror exam. I need to pass both so I could just ask her to tutor me."

Arena, Lily, and Mandy sat at the Gryffindor table eating their lunch while chatting quietly. Arena felt like something was off, it was just too quiet. Then it hit here, the Marauders weren't there.

"Where are the idiots and their king?" Arena asked, stopping Lily's and Mandy's conversation. They both looked at here before looking around the dining hall.

"There!" Mandy said, pointing towards the Ravenclaw table.

"They're talking to Troy." Lily spoke up causing Arena to sigh at the information. "Great. Just great." she said.

"So they're talking to your ex-boyfriend. It's not like Troy will really tell them anything." Mandy said.

"Yeah. You made him promise not to tell any one that your..." Lily started but was interrupted by Arena. "Shhh! I don't want to even hear it out loud. I know he won't tell them that."

"Well then stop worrying. It doesn't matter how much information Troy does give them." Lily told her, "You'll never, ever, fall for Sirius Black."

Later that day Arena was walking towards the tower when known other then Sirius Black fell into step bedside her.

"Hello Arena." he said with his trademark grin plastered on his face.

"What do you want Black?" she spat at him while trying to walk faster then him.

"Why do you think I need something?" he asked, "Couldn't I just be saying hello to you to be nice."

"You don't know the meaning of the word 'nice'." she said, "Now tell me what you want or leave me alone."

"Fine, fine, fine. I need you to tutor me." he finally said causing Arena to stop in the middle of the hall way. "You want me to what?" she asked.

"Tutor me." he repeated. "You see I want to become an auror and I obviously can't with my grades so I was wondering if you could help me. Just enough so that I can pass my NEWTs and Auror Exam."

"No." she said bluntly and started walking away.

"Please Arena!" Sirius whined. "I really need to pass. If I don't pass then I'll be forced to go into the family business! And then you'll have to go through life knowing that it's your fault there's another death eater out there." Arena sighed at his attempt to make her pity him. "Fine." she sighed, "Meet me in the library on Saturday." she added.

"Thank you!" he said happily and started to run down the hall way before being stopped by Arena. "And Black!" he heard her say, "If you make any attempt to ask me out the tutoring ends." He didn't say anything to her. He just nodded before turning back around and running towards his destination.

"YOU WHAT!" Lily shouted after Arena told her and Mandy the news.

"I said that I'd tutor him. But I also said that if he asked me out again the tutoring would end." Arena told them once again.

"But why?" Mandy asked, "All he does is annoy you and you suddenly decide you're just going to tutor him."

"He put on the pity act." Arena said, "He said that if I didn't tutor him then he'll fail his exams and go into the family business. And then it would be my fault that there's another death eater running around."

"And you bought that!" Lily said in shock causing Arena to snort, "Merlin no! But he was annoying me."

"Yes they do do that." Mandy said in a serious tone before chuckling. "Well good luck. When do you start anyway?"

"Saturday."

"You think this has anything to do with why he talked to Troy?" Lily asked as the three of them just remembered that small little fact.

"Probably." Mandy nodded.

"Well I'll just have to wait and see."

Saturday came around too quickly for the female Gryffindor. On the way to the library all she did was mutter about evil Gryffindors and stupid pity acts. Although Saturday came too quickly for Arena it came too slow for a certain Black. Ever since Arena had agreed to tutor him he's been jumping with joy. After all, to him, it was one step closer to getting James' broom.

"Hello my wonderful tutor!" Sirius said once he spotted Arena waiting for him outside the library doors.

"Lets just get this over with, shall we." Arena muttered before turning and walking into the library. Sirius followed her and followed her...and followed her. It seemed like she would never stop walking until finally she took a seat at a small table in the very back of the library. It was hidden from everyone and Sirius could help but wonder why she liked this table.

"What do you want to cover first?" Arena suddenly said, shaking Sirius out of his thoughts. "Um...how about you help me with Charms?" he said, however he never got an answer. When he looked up to see what happened Arena looking in the opposite direction. He then turned his attention to where he was looking and his jaw dropped. Only a few feet away stood Javen Blackwood. That wasn't the shocking part for he was talking to Peter Pettigrew. The two from enemy houses were actually having what looked to be a civilized conversation.

"Blood hell." Sirius muttered getting the attention of Arena. "I-I'm sure it's nothing." she said, not sure who she was trying to convince.

"Um...yeah he's probably just..." Sirius started and found that he couldn't finish. There was just no reason for Peter to talk to Javen. No reason at all.

"P-Peter will probably tell you idiots later." Arena said. "Why don't we just get started."

"So why are we doing this?" Remus asked, "Padfoot already has a plan." Currently him and James were walking around the school trying to find Andrew Church, the Hufflepuff that dated Arena.

"It's just in case his plan doesn't work." James told him, "After all it is always good to have a back up plan, right Moony?"

"Sure." Remus muttered. "I still can't believe you guys are going through with this bet. Arena doesn't deserve this."

"Be that as it may I want to see Padfoot proclaim his love for Snape." James said with a smirk. "Ah! There he is." Andrew Church was sitting by the lake with a group of his friends. They were laughing at something but neither Marauder really cared as they marched right over.

"Hey Church!" James shouted from a couple feet away. "I have to talk to you!" Andrew looked up from his friends and saw James waving him over.

"I'll be right back." he told his friends before getting up and walking over to the two Gryffindors. "What can I do for you two?" he asked.

"You can tell us about your relationship with one Arena Blackwood." James said right away.

"And why would you want to know about a relationship that ended two years ago?" Andrew asked.

"Well...you see, our friend wants to go out with Arena. Sadly she hates his guts. So we were wondering how the two of you got together." James said, careful not to name any names. It would be terrible for others to find out that Sirius couldn't get one girl to go out with him.

"Well if I remember Arena correctly then she probably has a pretty valid reason for hating your friend." Andrew stated.

"Will you please just tell us." Remus said getting annoyed by the Hufflepuff. Now understand it is very hard to get Remus to be annoyed. But the Hufflepuff in front of him was just drawing things out and wasn't answering their simple question.

"Fine I'll tell you." Andrew said. "We met over Summer at Diagon alley. She had just managed to ditch her family and was walking out of Knockturn alley when I ran into her. At first I wasn't interested and neither was she."

"Cut to the chase!" James shouted. "How did you two end up together!?"

"I'm getting there." Andrew sighed. "Anyway, neither of us were interested until we met again at Hogwarts. Her cousin was yelling at her for no reason. Now I knew I wouldn't stand a chance against her cousin so I waited until he was gone. Then I came ou of my hiding place and went to see if she was alright. After that everything just kind of fell into place."

"So why did you break up?" Remus asked.

"Well we dated for a year. Then her family found out she was dating a muggle-born." That was all he needed to say for the other two to understand.

"Thanks Church." James said before the two turned away and started walking back to the castle. "Alright so if this plan fails all we need to do is get Sirius to rescue Arena from her cousin." James said with a smile.

"You know I've noticed something." Remus said, "Every time Arena is dating someone her family interferes."

"What do you mean?" James asked causing Remus to sigh at his friends small brain. "Well think about it. When her and Troublefield her cousin threatened him if he didn't dump her." Remus began.

"...And then when Arena was dating Church her family managed to break them up again." James finished as he realized what Remus was going on about.

"So the question is why doesn't her family want her dating?" Remus said, "I mean I can understand them not liking Church but Troublfield's family is pure blooded."

"I'm sure we'll find out sooner or later." James said, "I wonder how the tutoring is going."

"I don't get it!" Sirius said and slumped back into his seat.

"What isn't there to get!" Arena shouted at him. "It's simple!" the two had already finished with Charms and moved onto another subject: Magical theory. The class delt with...well the theory behind magic.

"Why did you even take this class!?" she finally asked.

"I thought it would be easy." he stated with a pout causing Arena to sigh. "You might know how to do it but you don't know why it does that." she said. "And this a basic levitaing spell. You know how you do it now lets focus on why it does that."

"You tried explaining it to me!" Sirius said. "I just don't get it!"

"Well let me try something else." she said. "Why does your leg move?" she asked, confusing him a bit. "Um...because that's the way I was made." he said.

"Wrong." she said bluntly, "Your leg moves because in it are nerves. When you want to move your leg the brain sends a message through the nerves basically telling the nerves in your leg to move." she explained.

"Ok but what does this have to do with why a levitaing spell works?" Sirius asked.

"Well think of your wand as the brain and the object as the nerves." Arena told him and Sirius nodded. "Oh! So its like my wand sending out a message to the object that I want levitating?" he stated as a question.

"Basically. It's a bit more complex then that really but thats the basic outline." she smiled making the scar on her cheek a bit more noticeable.

"How'd that happen anyway?" Sirius suddenly causing Arena's hand to touch the scar. "Um...After I got sorted into Gryffindor my family was furious. First they tried to get me re-sorted, then they tried to get my out of Hogwarts." she told him, "Dumbledore wouldn't let them and right before I went home for the winter break they found out about my friendship with Lily."

"So they did that to you." he whispered and raised his hand to her cheek. His fingers gently ran the course of it, right from the bottom of the eye down to her chin. "Must of hurt." he said and took his hand away. Never noticing the slight blush that came to Arena's face at the contact.

"Yeah it did." she whispered before ruining the moment by clearing her throat. "I think that's enough for today. Same place same time." she said before standing up, grabbing her things, and practically running out of the library.

The weekend passed without too much drama. Arena told Lily and Mandy about the tutoring session but failed to mention the bit about Sirius touching her face. James and Remus told Sirius about their meeting with Church and Sirius told them everything about his meeting with Arena. Unfortunately for him he forgot all about seeing Peter with Javen.
