I honestly thought I'd uploaded this a long time ago. I feel shame. Lots and lots of shame. Sorry!

I can't think of an opening statement. Sorry guys :'(

[I tried writing this in third person, but I'm just no good at that. So please enjoy this chapter from each of the brother's point of views.]

Mike

This isn't good. I pace the lair frantically, trying to wrap my head around the situation. I still can't quite grasp what happened. She was right there. Right there in my arms. And then she wasn't. She came into the alleyway and I rushed to my best friend. Held her tight, glad that she made it back to us. She always makes it back to us. But I wanted her safe. I lead her back to the van, only to be pushed aside. She saved me! Lexi, my little sister, saved me and how did I repay her? By leaving her behind.

I didn't mean to do it. I'd never do that. Not to Lexi or any of my brothers. Or anyone, ever. Never leave someone behind. It all just happened so fast. She had passed out in my arms. She was smiling up at me. Even when the spark was leaving her eyes, it was like she was trying to say she didn't blame me. That it wasn't my fault. But it was. It is. Maybe not that she got hurt. Maybe not that she had to bail me out in the fight. Maybe not that she got shot instead of me. But leaving her behind. That will forever be my fault.

I punch the wall. The anger about all of this just takes me over. I've never been this angry in my life! I left her behind! Raph, the last person I'd expect, comes to my aid. He gently places a hand on my shoulder, "We'll get her back."

I turn to him with a deadly glare. Without a word, I turn and grab my skate board. Why couldn't she have waited to go top side until after I'd finished training? It'd only of been another half hour. Why didn't she make one of our brothers go with her? Was she looking for trouble? No. No, this isn't anyone's fault but my own. She passed out. I saw Hun. I attacked. And when I turned around, she was gone.

Leo told me to stay back at the lair. The he'd go out and find her. Somehow, he knows how angry I am and it's almost like I'm acting like Raph. But ten times more angry if that's possible. I'm a ticking time bomb which just isn't me. But they don't get it. Leo may think that we're all his responsibility. And we very well might be. But Lexi is my responsibility. Not only because she's my only younger sibling, but because she's my best friend. I look out for all of my brothers, I'd do anything for them, but when I comes to Lexi?

It's complicated.

When we first met, I'd saved her. I was her hero. And we became friends in an instant. It wasn't even a question. She didn't care about what I looked like, she didn't care about where I lived, she just didn't care. The only thing that she focused on was that I was a nice person who she got along with. And that's why I'd sneak out of the lair so that we could hang out. And that's why I taught her some ninjitsu that I'd been learning at the time. And that's why I stole some of Donnie's board games so we could play. And that's why I taught her to ride a skateboard. I wasn't just her hero because I saved her from falling and drowning. I was her hero because I was there for her when she was all alone. When she had no one.

And I let her down.

Leo told me to stay behind because he didn't know what I'd do. But I know what I'd do. What I will do. I'm going top side and I'm going to find a purple dragon or a foot soldier or anyone else and I'm going to make them tell me where she is. Lexi needs her hero now more than ever.

Don

I don't know what the guys are doing. I don't care. Right now, the only person on my mind is Lexi. She needs help. Whatever was injected into her couldn't have been kosher. It made her pass out. Lose balance. And something tells me that it's connected to the BioTech lab that Shredder took down. I have all of the pieces, I just have to connect them. Figure what's going on.

My fingers speed away on the keyboard. I've got another computer searching for any criminal activity. Anything that might lead to a food soldier. It may turn out the same as last time - an ambush - but we're all willing to risk it if there's even a chance of finding Lexi. A second computer is searching frantically for her shell signal. If the battery is ever put back in, then we'll get a ping and it'll lead us right to her. Or, again, an ambush. But like I said, we don't care. At least I don't. And I'll go in and get her myself if I have to. But I won't have to. I'm not the only one in turmoil right now.

Mike must feel like crap.

It's not his fault.

It's mine.

It's my fault she'd even gone out there in the first place. I should have made her stay with the van. I should have thought of a way to get everyone out before we stormed in. I should have thought of a better plan than having Lexi take off by herself as bait so the rest of us could get out. Even before tonight. Yesterday. At the BioTech facility. She called me. I knew there was a fire. We'd of gotten there in time. One of us could have helped her get people out while the other three took on Hun and the Shredder. It'd of been easier because we'd of had more man power while he had less. All in all, it's my fault she was in the situation in the first place.

April crouches down beside me, seeing how I'm immersed in my work, "Why don't you take a break Don? You've been working non stop and there aren't any new leads. Your computers are doing everything they can to-"

"I'm not stopping," I insist, "I'm going to find her. And I need to be ready for when we do. We have no idea what was in that serum or what it did to her."

April sighs, "I understand, Donnie, but-"

"No buts," I growl, "I'm going to find her." April doesn't try again after that.

The BioTech facility had been working on three different chemicals at the time. Two are very unlikely in that they are for cosmetics and animal treatments. But the third has been classified by the DOD. It's a military weapon and that screams 'Shredder come steal me!' I've been trying to break into the system for forever now but I'm not making any progress.

I don't know what's wrong with me. I can usually do this kind of infiltration in half an hour tops. But this is ridiculous. It's like the entire file had been redacted and I have to fill in the blanks. I've got four different algorithms going to figure this out. And from what I can tell from what little I've got, this doesn't look good.

It seems that the serum was a military grade hypnotic drug. It was supposed to be thrown out and trashed, but the DOD has kept the project going under wraps. It has something to do with spies in enemy territory and memory wiping. As more and more of the file becomes clear, I realize that the drugs is used to wipe a soldiers memory as a last case scenario. Their fighting, language, and intellectual skills all stay in tact. But as for things like who they work for, their memories, and even their names, it's all taken away.

What would the Shredder want with something like that?

Raph

I sit in the corner of the lair, head buried in my knees. How could I have let this happen? It was my idea to go on a run. It was my stupid decision that got the Shredder on our tail. It was my bonehead move to go along with her plan. Why did she have to run off by herself? She could have gone to the van with us. We'd of found a way. But I wouldn't have been strong enough to take on Hun and Karai again. And she knew it. Why did she have to know it?

I hear the familiar smack of flesh on brick and my head whips around to watch a site I'd never thought I'd see; Mike punched the wall. I get up fast, going to his aid. Mike must truly hate himself for what happened. He just doesn't understand that it wasn't his fault. It's not anyone's fault but mine and we'd had a line of defense up. No one was getting past us. I still don't know how they managed to take her without us seeing.

With my hot-head roll taken by my little brother, I realize that what my siblings need right now is Mike's care free spirit. And with Leo out with Casey and Don working hard in the lab, I have to take the roll, "We'll get her back."

Mike turns to me with a fire in his eyes. He doesn't want to hear it. Getting her back means that she's not here. It just reminds him of his mistakes. We all made mistakes tonight. But when it comes to Lex, Mike will always take the fall. Even if he's not there when she gets hurt.

Mike doesn't say a word, which is very unlike him. He shrugs my hand away, grabbing his board and leaves. I should have gone with her. If I'd of just gotten out of my head and gone with her, I'd of been there for the fire. Helped her get the people to safety. Stopped the Shredder from taking whatever he took that he used against my sister. I should have gotten out of my head.

Leo

Casey and I scan the city for anything. Anything at all that will lead us to Lexi. It's been half an hour since she disappeared. She could be anywhere in the city. And it's a big city.

Don's got some scans going that should find her if her phone gets turned back on and Casey is covering the ground level, asking if anyone has seen her. I take the rooftops, being unseen. I look in alleyways, trying to find some purple dragons or foot soldiers that will lead me to a base. It will be a start. It may be like last time, but I'm willing to risk it. No one threatens my family and gets away with it.

I can't believe I yelled at her. She was doing what she thought was right. She came to save us even though she was injured. She risked her own skin so that we could get safe. But most of all, she pushed Mike out of the way.

I don't know where Lexi came from before she joined our family and, ninety nine percent of the time, I honestly don't care. She's family. She always will be. But sometimes I forget that. Sometimes I see my sister and brothers as soldiers and not as vulnerable ninjas in training. I was harsh on her. And she saved Mike. For whatever reason she did it, she did. And I will be eternally grateful for that.

She would do that for any of us. Though, I have a feeling, Mike especially. They've known each other the longest. It was at least three months before Mike introduced her to Splinter and another week before Splinter brought her into our home. I was unsure of her at first. I trusted Splinter's judgment, and looked out for her when she was in trouble, but it wasn't until a week after she was living with us that I officially made her family.

She'd already been best friends with Mike, and Don was easy to get along with because he likes everyone. It took a while for him to trust her, but she got through to him first. It took Raph at least a month to even speak to her. Longer to let her play with him. I don't know when things changed, but now days Raph is always looking out for her. Questioning every decision she makes and always making time for her. Sometimes I get jealous of their close relationship - and I know that Mike does. I don't know what happened between them, but I do know what happened between us.

I was nice and polite and courteous to our house guest. Splinter had told me to be. She was shy at first, only opening up around Mike. She hardly ever spoke and only did so when asked. It was weird. Like she was a robot with only 'yes' or 'no' answers. And Splinter had told us very sternly never to ask where she came from. (Though, I've always been curious.) About a week into her stay, she noticed me meditating. I could tell she wanted to ask me something, but I guess she'd seen that I get irritated sometimes when my brothers interrupt my alone time. So, instead of walking away and pretending and instead of interrupting me, she sat down. She crossed her legs and meditated across from me. I'm not sure she knew what she was doing, but she tried to do something that she knew interested me. And when I had finished, and asked her if she needed something, she said she wanted to play with me.

I couldn't believe it. The strange girl who was attached to Mike's hip wanted to play with me. After having just spent close to an hour trying to meditate. And then a thought had clicked; she wanted to play with me over Mike. I smiled back and agreed and we played board games for hours. Even when Mike tried to join, she politely declined, saying that she needed some time with just her and me. I don't know why, but it made me feel special. But something about it still gets me. It's almost like she and Mike had planned it. Planned it so that I would feel good and like her. I think this way because, knowing Mike, he'd of gotten upset - like he has every other time she turns him down. But that day, that day he just shrugged and said 'have fun'.

Truth is, I don't care if she tricked me. I don't care where she came from. I don't care about anything but the fact that she is my little sister and she's missing. And I'm going to do everything in my power to find her and bring her home.

April

I'm getting really worried about the guys. I've been stressed out, too, with wondering where Lexi went. I've always thought of her as like a niece or a little sister or a very close friend. Especially when most days I'm surrounded by four teenage boys, an experienced male, and a man that acts like a teenager. Sometimes it's just nice to have a girl around. Even is she is a total Tom Boy.

It's been three days. I've seen Leo maybe twice when he's walked into the lab to get information from Don. And seeing as how Don hasn't found anything new on her location, he always leaves right after. Just comes in, asks if Don has anything, and leaves. He goes topside again and I don't see him until the next day when he asks again. This time looking completely wiped out. Like he's been looking all night. And, according to Casey, that's exactly what he's been doing.

Don is a wreak himself. I've seen him leave his computer once for the bathroom but hasn't eaten or slept as far as I know. He just crouches over the computer. I keep trying to get him to take a break. Let his mind rest, but he doesn't listen. Lexi would be able to pull him out in seconds. I still don't know how she does it.

Honestly, though, it's Raph and Mike who worry me. Mike the most. And that's saying something. Raph has been quiet. He doesn't get angry and punch things like he normally does. It's like his anger is one step past 'seeing red' as he puts it. And the new step is scarier than anything. He wants to leave to help Leo, but knows if he does, he'll do more than rough someone up. Not knowing any ways to help, he just stays within himself. Waiting to be told where to aim and how hard to strike.

And then there's Mikey. Being a complete one eighty from his usual self, he's enraged. Fumed beyond belief. I've seen Mike irritated when his brothers make fun of super heroes or his comics, but never anything to this extent. And just like Leo, he's rarely here. His knuckles look a little roughed up and when I was finally able to get something out of Raph, he'd told me that Mike punched a wall. I know that he and Lex are close - closer than anyone - and I understand that we're all upset and worried, but his behavior scares me. And I'm not the only one.

Splinter is just as worried as the rest of us. He tends to meditate for long hours, somehow searching for Lexi's 'ora' as he'd explained it to me earlier. He's not angry at his sons, though I'm sure they all think he's disappointed. He's not though, because he believes in his sons. And his daughter. We'll find her. It's only a matter of time.

Casey and I are unsure what to do. He's been riding around town, asking anyone who will listen, if they know where she went. He says that Leo goes out when he does, but doesn't get back until hours later. Case is even upset with himself because he couldn't help them in the fight. He'd been on the other side of town when Raph had called for backup and he'd of never gotten there in time. But Casey couldn't have known it was going to happen.

I'd say I blamed myself for letting Lex go that night, but, in all honesty, I'd of never been able to stop her. She was going to save her brothers, even though she was hurt. It wasn't even a question. And, I'm sure that if she's well enough to be thinking, that she doesn't blame any of us. Because there is no one to blame. She'll come home and everyone will forget about it. And she'll get better. And then they'll all go on another mission where something else will happen. And they'll all blame themselves, though there will be no one to blame.
