A/N: Hi guys, it's Angel. So recently I've gotten really into Lab Rats and I've had this idea knocking around in my head for a while and it just wouldn't go away. So here's my little prologue for it, tell me what you think. I hope you like it!

Warning: Some of the characters may seem OOC to you, but this is because the show hasn't given us full personality views of them all, so this is my interpretation of them. They are the way I see them being, and you might not agree with me. Leo will DEFINITELY seem OOC, but there is a major reason for that which won't be revealed in this prologue, but should be revealed next chappie. Well that is if I continue writing this, which all depends on if you guys like it or not.

Disclaimer: If I owned Lab Rats, I'd be writing a script for the next episode, not a Fanfiction of what I wish would happen.

Adam's POV

Leo and Marcus were at each other's throats again. I wish those two would just get along. I think they would find that they have a lot in common. I have to admit Leo insisting Marcus is evil makes them getting along hard, but Marcus wasn't exactly behaving in a way towards Leo that would say otherwise I guess.

I wasn't really paying much attention to what they were saying; it was just the usual 'You're evil' 'No I'm not' stuff. "You're just jealous because Adam, Bree, and Chase like me better than they like you." Marcus declared.

Okay, now that was out of line, and so not true. Marcus was a cool friend and all, but Leo was our best friend AND our brother. If it came down where I had to make a choice between the two of them, as much as I'd miss Marcus (he was pretty much our first real friend besides Leo and Caitlin for Bree), I'd still choose Leo, and I'm pretty sure Bree and Chase would do the same. I hoped Leo knew that and didn't react too badly.

"I am not jealous; they will see the truth eventually mark my words. And they certainly don't like you more than me." Leo countered in a cold, angry voice. What happened next shocked the living daylights out of me. What are living daylights anyway? Are they like live pieces of sunshine or... Wait, who cares? Back to what happened, Marcus punched Leo. Right in the face. It must have been pretty hard too because the force knocked Leo back into the table. Leo may be a small guy, but it would still take a fair amount of force to knock him back a foot into a table.

I immediately pushed Marcus away from Leo, and went to see if Leo was okay, Bree and Chase right behind me. Leo's eye was starting to swell a bit, and the skin around it had broke open and was bleeding. "He should get to the nurse's office." I proclaimed to my bionic siblings.

We decided since it would be a little crowded if we all went to the nurse's office, only I would go. I could see Bree and Chase both really wanted to go, but we decided on me since if Leo started being resistant I was the one that could carry him the easiest. Thank you super strength. I helped him up, and walked with him out of the cafeteria and down the hall towards the nurse's office.

Leo seemed to be getting more and more nervous with each step we took, and I wasn't sure why. He had been acting very strangely lately. He had gone from being all upbeat, loud, and outspoken, to quiet, reserved, and I don't know just…distant. Like something otherworldly had happened to him. He spent most of his time these days scribbling in a black notebook. He rarely came down to watch us train anymore, only really coming to the lab when he was needed there as the Strategic Mission Specialist. I kinda missed him, and I was definitely worried about him.

"You know Adam, I'm fine. I don't really need to go to the nurse's office. I'll just rest a bit, put some ice on it, no big deal." Leo uttered, trying to be casual. Okay, now I was really suspicious. Leo had been turning every little thing Marcus did or touched into evidence that's he's evil and up to no good, and then when Marcus does something really bad to him, all of the sudden it's no big deal. That just doesn't add up. Not that I pretend to be any good at adding, but I'm fairly certain it doesn't add up. What I'm saying is something's not right.

"No Leo, you need to get checked out, your eye looks pretty bad." I asserted, not wavering on this. "But-" He started. "Leo, you're going to the nurse's office. Whether you walk or I have to carry you is up to you, but you are going." I firmly stated. Looking defeated and worried, he sighed. My suspicions grew even more. I was terribly curious as to what caused this change in Leo, but I had a feeling it wasn't a good thing.

We reach the nurses office and walked in, Leo practically shaking from nerves now, and I was more desperate than ever to know what was going on. "Hey Nurse Jacklyn Smith." I said reading off her name tag. "My brother here got punched and slammed back into a lunch table, could you check him out please?" She smiled at Leo and I. "Of course sweetie, and please, call me Jackie." She replied kindly. I smiled back at her; she seemed like a nice woman. "I'm Adam and this is Leo." I said, motioning to my brother as I said his name.

She walked over to us as I sat down in an extra wood chair over by the door while Leo reluctantly took a seat in the armchair near Jackie's equipment cabinet.

"Alrighty, let's take a look at you. Well, it's swelling some and the skin broke open, must have been a really hard punch, doesn't look like the actual eyeball was damaged at all, that's good." Jackie said, seeming to be more of talking to herself than us. "We just need to clean the cuts around your eye, then just put some ice on it. That's about all you can do, it should bruise over and heal in a few days." Well that was good news. It would be sore, but the damage wasn't too bad. "Now let me check your back real quick to make sure there's no bruising from where you slammed into the table." She stated, turning the chair slightly for a better angle.

Leo flipped. "No, I'm fine. My back doesn't hurt at all. I didn't even hit the table that hard." Leo stuttered anxiously. Okay, what is going on? I didn't know, but I was gonna find out. "He's a little shy Jackie. You know what, my dad's a scientist, and because he sometimes does experiments at home he taught me and my siblings first aid in case one ever went haywire near us. Is it okay if I take a look, and I'll tell you if I see anything that needs your attention?" I compromised. "I don't see a problem with that. I'll step outside just call me back when you're done." She agreed, strutting out of the office, shutting the heavy wooden door behind her.

I turned back to Leo, who now had a look of fear on his face. He wasn't afraid of me was he? I sure hope not, he's my baby brother. "Leo, lift the back of your shirt." I said in a gentle but firm voice letting him know he was not getting out of this. He shook his head frantically. "Leo come on, it's just me. Your awesome big brother. You don't need to be scared of whatever's been going on with you lately. It's not here, and if it was I wouldn't let it hurt you." I reasoned slowly walking towards him. "Nothing's going on with me." He countered anxiously. "Leo, you may not have been my baby brother as long as Chase has, but I can still tell when something's going on with you, and something is." I retaliated. I was worried and he wouldn't budge, so I just walked over an lifted the back of his shirt up myself.

My blood ran cold. I've never understood that expression until now. It's when it feels like everything in your body has stopped, your heart stops beating, your blood stops pumping, and you just feel frozen. Like I was frozen in horror right now.

"Adam, I can explain."

Reviews make my day, whether they say you loved the chappie or you thought it sucked. Plus, I will only continue this if people like it, otherwise it will just have to stay in my head. Oh, and please inform me of any grammar mistakes I may have made. Thanks, hopefully I'll see you next chappie!
