"So, did you meet your brother?" Milliardo Peacecraft asked later that day. Mac looked at the computer from her bed. She got up and walked over to it. She sat down at her desk.

"Well, in a matter of speaking." Mac said. Milliardo raised an eyebrow.

"What's that supposed to mean?" he asked.

"Well, I literally ran into him, and then he asked me a few questions and then we parted." Mac said.

"Does he know?" Milliardo asked.

"Milli, does he know what? That I'm a girl? No, he doesn't know that. Does he know I'm his 'brother'? Yes." Mac said.

"Mac, you need to tell him you're a girl." Milliardo said.

"Milli, I can't. Not yet anyway. I need to prove myself first. Once I've done that, I will." Mac pleaded with her sponsor.

"Mac," Milliardo sighed. "You know that always backfires. You have to tell him now, or he'll find out the wrong way. Duo doesn't do well with being lied to, because he never does it."

"I know, I know, but I still want to keep it a secret for awhile longer." Mac said.

"Mac, you are just as stubborn as your brother." Milliardo said. Mac smiled.

"Thanks Milli!" she said. Milliardo tried to look stern.

"But, Mac. If I hear anything but wonderful reports from Sally, you are out of there and back here and working for me and Noin forever!" Milliardo told her. Mac sobered up.

"Okay, Milli. Believe me, you won't." Mac promised.

"Good. You've been known to start fights and lose your temper. Try to keep a rein on it, huh? Try for me and Noin if not for yourself." Milliardo asked her.

"I'll try." Mac promised.

"You have to do it!" Milliardo said.

"Trying is the best I can do with something like this." Mac informed him. "Now, can I talk to Noin?"

Milliardo sighed again. Mac always was difficult. "I suppose." He said. Noin came up on the computer screen in place of Milliardo.

"Hi Noin!" Mac said.

"Hi Mac." Noin said.

"So, has Milli been giving you grief about me coming here?" Mac asked.

"Yes, he keeps saying that a girl shouldn't be in Preventors and that we should send for you right away. I keep telling him that I was a soldier, but you know Milli." Noin said. Mac laughed.

"That sounds like him. I'm glad I met you two. Otherwise I never would have gotten here or out of the Robertson's." Mac said.

"Hey, have you told Duo?" Noin asked.

"Told him what? That I'm a girl? No. Told him I'm his 'brother'? Yes. Or that you and Milli are my sponsors? No. I think he might blow a fuse if I told him that. Then he would go marching up to you guys and ask all about me, and I want to be the one to tell him about me. It's too dangerous to tell him anything besides I'm his 'brother' right now." Mac told Noin.

"You are just as stubborn as your brother!" Noin cried in exasperation. Mac just smiled at her.

"Milli says that if I make just one mistake he'll take me out and I have to go live with you guys. Isn't that a bit harsh?" Mac asked. Noin looked at her.

"I don't think so. I really believe that if you can't handle your temper there, then you can't stay. Although, they might kick you out before Milli can get there if you start a fight like the last one." Noin warned.

Mac winced remembering her last fight. She had been mad because she had just had a fight with her foster units and then someone started making fun of her being an orphan. She had taken out all her anger on that one person and left them in the hospital. That was when she went to Milliardo and Noin because they could train her to do what was right and not lose her temper.

"I understand, Noin. Listen, I gotta go, but I'll talk to you later, okay?" Mac said.

"Yes, that's fine. See ya later." Noin said as they signed off. Mac looked at her blank computer screen. Then, she stood up and got her pack and walked out the door.

She headed down the dark and deserted halls towards the office. She crept quietly down the hallways, hoping she wouldn't wake anyone up. She knew that she would get in trouble if she was caught, but then, she wouldn't get caught.

She picked the lock on the office, and went in. She turned her flashlight on. She went into the file cabinets to see if she could find her file.

"AHA!" she whispered. She opened her file and sat down to read it. She skimmed down from what she wrote to her history.

Stayed with Robertson's for ten years. Then went to unknown friends. While there, subject was taught more martial arts and perfected what subject knew. Subject was taught fencing and how to drive mobile suits. Several hours at a time, subject would disappear and do unknown things.

Mac read only that. She was about to turn the page, when the light was turned on.

"Hey! What are you doing in here?" someone yelled. Mac looked up. Duo was standing in the doorway, blocking her only escape. "Mac?" Duo asked, incredulously.

Mac looked sheepish. "Yes?" she asked meekly.

"What the hell are you doing here?" he asked.

"Looking." She said.

"Looking for what?"

"My file."

"I see you found it. Why are you in here? You aren't supposed to be in here or out of your room." Mac looked back at her hands.

"I just wanted to see what was sent for my history." She mumbled.

"Well, you always could have asked." Duo said. They sat there for a few uncomfortable minutes of silence.

"Duo," Mac said. Duo looked at her. "There are some things that I'm not telling you." Duo lifted a quizzical eyebrow.

"Like what?" Duo asked.

"You have to promise you won't freak out or tell anyone." Mac said.

"I can't promise that." Duo said.

"I know you don't lie, but you don't have to say anything at all." Mac said. "If someone asks you, you can tell the truth, but just don't tell anyone."

Duo considered this. "I can't promise I won't freak out, but I promise I won't tell anyone unless they ask straight on." Duo finally said.

"Duo, you know how you said, that you remembered a girl." Mac said. Duo sat there, waiting for Mac to go on, and then a look of understanding crossed his face.

"You mean." Duo said. Mac nodded. "I don't have a brother, I have a sister?" Mac nodded again. Mac told him about what happened, leaving Noin and Milliardo out. "Is there anything else you are hiding?" Duo asked.

"Yes." Mac said. Duo looked at her expectantly. "Duo, you might not like this." Duo braced himself for the worst.

"Go on." Duo urged her.

"The unknown friends.well they are um. Milli and Noin." Mac said. Duo had braced himself for the worst, but this was beyond the worst for him.

"WHAT?" he roared.

"Shush!" Mac said. Duo sat there panting, trying to let it all sink in. "I got into a really bad fight that left someone in the hospital and so they had to remove me from the foster units. They put me in an orphanage again. Noin came one day just because she wanted to see the kids and she saw me. She said later that she recognized me as someone who looked a lot like you and so she adopted me." Mac explained.

"So, you were staying with Milli and Noin for four years?" Duo asked.

"Yes. Listen, I know that Milli was once your enemy, but he's not anymore and believe me, he does like you gundam pilots." Mac said.

"I know. Lately he's been in touch with us. It's weird because he never would talk to us before, but now since he married Noin, we've all been in touch more. I'm still a little suspicious. So, you're a girl." Duo said.

"How observant of you." Mac said. "I wasn't going to tell you for awhile, but Milli made me. He said that no matter what, that sort of plan always backfires. You would have found out the wrong way because I would get hurt or something where they would notify the whole school. I'm sorry, I didn't want to tell you, but Milli made me." Mac sighed.

"I know. I always have those kind of plans." Duo said. He smiled at his sister. "So, tell me little sister, what happened in these hours of disappearance?"

Mac shook her head. "I have to have some secrets." Duo looked at her, surprised. "I can't tell you now, but I'll tell you when I feel it's time."

"God, you and Heero! You always have secrets and feel like keeping the rest of us in suspense." Duo complained. Mac smiled.

"I like having some secrets." Mac said. Duo rolled his eyes. "The biggest difference between us is that you never lie, and that is one of the best things I do."

Duo looked at her. "Just don't lie to me. In my opinion, that's the coward's way out, but in cases like this, you need to lie. But, not too much longer. You have to tell everyone."

"I know. I plan to. I plan to do it when I graduate." Mac said. Duo shook his head.

"Too late. You have to do it sooner."

"Duo!" Mac whined.

"No, you can wait only till the end of this semester." Duo said firmly.

"Duo! They'll kick me out! I want to do this!" Mac pleaded.

"No. I can't let you lie." Duo said.

"Duuuuoooo!" Mac whined.

"Nope, but I'll let you stay with me if they kick you out.

"I guess that's a fair deal. I still think that you should let me go through with it my way." Mac agreed.

"No, little sis. I've had way too many plans like that. They all backfired." Duo said.

"Oh, you mean like the endless times you tried to self detonate but it never worked?" Mac asked evilly. Duo looked at her in surprise.

"How-how did you know about that?" Duo asked. Mac smiled evilly.

"You'd be surprised how many people were watching. The Dr. told me about the time when you tried to blow up you and everyone else one time. Oh, and so many more!" Mac said. With that she walked out the door. She turned around and winked at Duo. Then, she made her way back to her room. Duo sat there in shock.

"You have one hell of a sister." A voice said behind Duo. Duo whirled around. Heero stood in the corner, smirking.

"You're tellin' me!" Duo said. Heero just kept smirking.

"So, you aren't the only one to know about your humiliating failure with your plans. To top it off, you admitted it." Heero said, rubbing it in.

Duo made a face. "Yeah, yeah, just don't tell anyone, okay?"

"Maybe." Heero said and walked out the door. Duo buried his face in his hands.

"What have I gotten into?" Duo muttered.
