Sorry that it took so long to get this chapter out. I just discovered that I had typed up notes for this story, so once I read them I remembered what I was doing with this story. It so helps to write up notes for stories, then if you loose track to what you were doing, you can get back on track. So enough of my babbling and on with the story.

Chapter 4

It was starting to get late in the evening and just about everyone had gone to bed. Quatre and Trowa walked into the living room to find Serena asleep on the couch. Quatre smiled, she looked so peaceful laying there. As if there was nothing bothering her. Trowa looked over to Quatre and noticed the smile and decided that he would go and bring her to her own bed. Quatre saw what Trowa was about to do, but he assured him that he would be careful as not to wake her up. Once Trowa had Serena in his arms, Quatre lead the way to her room. Trowa laid her down carefully as to not to wake her up. Quatre took the covers at the bottom of her bed and covered her up.

Quatre and Trowa stood at the doorway, mainly with Quatre giving a loving brotherly smile. "Trowa, thanks for your help back in the music room." Quatre said, still looking at Serena's sleeping form.

"I had a feeling that there was a reason you started playing out of no where." Trowa started to explain, "When I saw the look on her face, I knew why."

"And that's why I'm thanking you. You didn't have to do that." Quatre said, this time turning his attention to Trowa.

"How did she know how to play the violin like that?" Trowa asked, changing the subject at the same time.

"We learned together." Quatre simply said, lightly smiling at his sister. The two stood there for a couple more minutes then left, closing the door slowly and quietly as to try and not wake her up.

The next morning was peaceful, until Serena woke up.

Wufei was about to come out of the training room when he heard a scream. When he opened the door, the first thing that he saw was a black streak run by. He recognized that black streak, it was Duo and he was running from something, and for once it wasn't from him. Now he had to find out what he was running away from. Of course he didn't even have to take one step to find his answer. He caught a streak of blond run by just then, and he knew who it was Duo was running from, it was Quatre's twin sister. Wufei knew that Duo was in for it this time, that is if Quatre ever found out. Wufei had to go and watch Duo get what he deserved, so he continued on his way out of the training room, down the hall, until he came to a stop at the bottom of stairs.

What he saw didn't please him, Duo was still being chased with in the living room, and Quatre was no where in site. He knew it only had to be a matter of time before Quatre came to find out what all the noise was about.

It seemed like there would be no end until Serena got her target and paid him back for what he did. By this time, almost everyone in the mansion was watching the chase. All of the Gundam Pilots were there, except Quatre, who was still no where in site.

But the chase ended when Rashid made his presence known. He ran over to Serena and held her back from going over to Duo, who was now hiding behind the couch.

"Rashid let me go!" Serena commanded.

"I'm sorry Serena, but I can't do that. I know how you get when you want to get someone back for a practical joke that they have played on you." Rashid explained his actions.

Duo took that precise moment to take a peek over the top of the couch. And what he saw reminded him of when Quatre first tried out the Zero System. Now he knew that Serena really was Quatre's sister. So Duo was going to do the only thing he could think of to try and calm her down.

"Serena, I'm sorry. That prank wasn't meant for you, I swear!" Duo practically pleaded, standing up and holding his hands up in surrender.

It was at that time that Quatre decided to make is appearance, "Rashid, what is going on in here?"

"Took you long enough to get here, Winner." Wufei said crossing his arms and leaning against the banister. Quatre glanced at Wufei, then turned his attention back to Rashid.

"Master Quatre…" Was all Rashid could get out, for Quatre interrupted him, noticing that Rashid was holding back his sister from, what it looked like to him, kept his sister from killing someone. Then he noticed who Serena was trying to get too.

"Duo, what did you do?" This simple question was on the verge of sounding like a demand.

Now Duo knew he was in for it. He really didn't want to mess with and angry Quatre. He wasn't that suicidal, "Quatre…buddy…that little…prank wasn't meant for your sister, I promise!"

Quatre never took his eyes off of Duo, "Rashid…"

"Yes, Master Quatre?" Rashid replied.

"Release Serena." Quatre ordered, still not taking his eyes off of Duo.

Rashid hesitated for a moment before complying to Quatre's order. And to Rashid's surprise, Serena didn't go anywhere. Instead she just stood there, fists clenched, and fuming.

"I don't need this right now! And I don't need it from you…I don't need it from anyone!" Serena shouted before running off, and headed back upstairs.

Duo watched her go, thinking he kind of got off a little easy. But he was forgetting about one thing, and it was about to make itself known again.

"DUO!" Quatre practically shouted.

'Uh oh, now I'm in for it.' Duo thought to himself, almost wincing at the thought.

"Duo, incase you haven't noticed. When she came here, she was upset about something. And it really wasn't a bright idea for her to get caught up in one of your pranks. She really doesn't need another reason to be even more upset." Quatre scolded. "Now if you'll excuse me, I have to go and make sure she doesn't go and do something stupid." With that said, Quatre took off in the direction Serena did, once again wondering what had upset his sister in the first place.

Serena always did like the balcony that was connected to her room. It always gave her the best view of the flower garden. 'I wonder, if that prank wasn't meant for me, than who was it meant for?' Serena sighed, wondering to herself.

Just then she heard a knock at her door, then she heard a voice call out to her on the other side of the door, "Serena, it's me. Can I come in?

"I don't see why not." Serena answered. With that said, the door opened to reveal Quatre standing there in the doorway. He closed the door once he found where his sister was and walked further into the room.

"Serena, Duo's pranks are usually meant for Wufei." Quatre explained.

"So…" Serena didn't even bother to give her brother her full attention. Instead she just continued to look out at the landscape before her.

"You just got caught in his prank. He really didn't mean it." Quatre tried to reason.

"I know." Serena similarly stated.

"You do?" Quatre asked, walking up closer to his sister.

"Why do you think I left Duo alone when Rashid held me back and he was behind the couch?" Serena answered with a question of her own.

'That's what I was hoping was the reason.' Quatre thought, giving a light sigh, hoping that his sister didn't notice it.

There was a couple of minutes of silence between the two before Quatre spoke again, "Serena, I was wondering, you seemed so sad and upset when you got here, I was wondering and hoping that you might want to talk about it. It might help you feel better."

This time, Serena turned to face her brother. It took her awhile to find her voice, "It's along story."

"I have time." Quatre said, standing next to his sister now. Serena nodded her head, and Quatre took her hand and lead back into her room, sat her down on her bed, with Quatre sitting down next to her.

Serena sat there for a moment, contemplating where she should start, "Well, I had more than a little argument with some friends of mine back down on Earth. I needed to get away, so I came to the first place I could think of…I came here."

Rena Moon Well how the scene in the music room came about, I was listening to a Gundam Wing MP3 called "Tokimeite Harmony", it's an MP3 that plays the duet that Quatre and Trowa played together is the series. That's what inspired that scene to come about. Thanks for the compliment!

sailor-star-healer-5000: I don't know yet where I'm going to go with who Serena will pair up with (if at all). But if you like Duo/Serena pairings, I think I'll be making my other Gundam Wing/Sailor Moon crossover "The Scout Pilot" a Duo/Serena pairing.

youko's kitsune lovergurl: I haven't quit decided yet if the inners and Darien will show up, they might, but we'll have to see where my mind takes me on that one. So, Duo/Serena pairing is your favorite, well, like I told sailor-star-healer-5000, my other Gundam Wing/Sailor Moon crossover "The Scout Pilot" may end up being a Duo/Serena pairing. And I'm pretty sure that the outers will make an appearance, but I don't think I'll be pairing them up with anyone though.

PadFootCc: Serena upset? Hm…where did that happen? And I didn't mean to make it so Quatre had a hard time telling the others that Serena was his twin, it just sorta came out that way I guess.

chaoticwisdom: I made Duo shocked! Where and when did that happen! Oh great, now my mind is starting to fail me already…I don't have that great of a memory. : p

yashagrl: I…I'm at a loss for words…Thank you!

silvermoongoddess58: As funny as that would be, I don't think I'll do that. starts to think Well, maybe to Duo. snickers

Serenity8853452: Thanks for the complement. I love toying with Duo, imagining the looks on his face is the fun part of the job of writing stories with Duo in them!

Anime Monster: You don't need to worry…Serena will not end up with him! If anything, she will end up with one of the G-boys…minus Quatre that is.

ymari89: Thank you for the complement. I really appreciate it!
