Okay, so this idea has been in my head for a while. I'm super nervous. I guess that's a first crossover thing? And a new fandom thing? Austin and Ally lovers, and Lab Rats fans, you clicked on this for a reason, didn't you? Well, I'll tell you, this story (hopefully) will not disappoint! And if you are reading In Love With A Monster, I'm sorry. I'm having a little writers block. I've got the basic idea for the chapter, but I'm having trouble with the details. It will probably be up soon, though!

Enough of my rambling, let's get on with the first chapter of Siblings and Scars!

I don't own Lab Rats, Austin and Ally, or any of the characters, just this story, the plot, and anything else you don't recognize.

**Austin's POV**

I was just thinking back a long while ago, about what my best friend, Dez, had said to me. It reminded me an awful lot of... him. The one I'll most likely never see again. The one I was torn apart from. That was when I was 8. I haven't seen him since. I can't stop thinking about what Dez said. It's been driving me nuts. It went a little something like this:

Dez sniffs a bunch of things in the Sonic Boom store. What was he doing?

"What are you doing?" I ask, confused.

"Using my superhuman sense of smell to find Ally's book" Dez replies, then continues sniffing everything.

"You have a superhuman sense of smell?" I ask, pained by the phrase, but trying to hide it.

The smelling thing, in case you haven't figured that out. It made me think about... No. I swore to myself I would never bring it up again, why would I now?

"Austin? Hello?" Ally waves her hand in front of my face from her spot next to me at the piano. Oh, right! We're writing a song!

"Huh? Oh, yeah!" I pretend like I heard her.

"Well then do it," Ally replies, gesturing to the piano keys. Oh, boy. She told me to play something while I was in my daze.

"Do it. Okay... easy," I lie, placing my fingers on the keys. She is watching me like a hawk. This isn't going to end well.

I play a series of random notes, and Ally gives me a look.

"Okay, I wasn't listening," I admit immediately after four random chords.

"Clearly," Ally responds, giving me a look. "Pay attention this time,"

I try to, but it's really bugging me. I can't focus on anything but it.

"Got it?" Ally asks. Shoot.

"No," I flat out admit it this time. She gives me 'that look' again.

"Sorry!" I apologize.

"Is everything alright?" she asks, her attention away from the song now.

"Yeah... everything's fine," I fib, but maybe Ally knows me a bit too well, because she doesn't look like she's buying it.

"Stop lying," Ally replies glaring at me.

I turn my phone off of vibrate and back on it again to make it buzz. "Oh, my dad texted. I've got to go see him right now." I excuse myself and leave. On an unrelated note, I wish Mike Moon was my real dad.

**Ally's POV**

That was weird. Austin would never leave in the middle of writing a song, no matter what his dad said to do. There's got to be something wrong, he just doesn't want to admit it. Doesn't he know he can tell me anything? What if he doesn't know that?

I speedwalk up to him and ask again, "What's wrong?"

"Nothing's wrong!' he answers the same as before. I will get him to crack.

"You know you can tell me anything right? Anything at all," I suggest.

"Okay," Austin says as if it were some easy order, like... playing a song. I know how I'll at least get him back.

"You know you ditched me in the middle of a song, right?"

He stops right in his tracks and turns around. Yes!

""We'll finish tomorrow," Austin says. That was not the reaction I was looking for. They expect the song to be done tomorrow!

"But Austin, they-" I start, but I soon find that he's already gone. To where, I don't know. To do what, I have no clue. All I know is that he wants to be alone. I'll respect that. But I am going to get to the bottom of this. What does he want to hide from me? What could sweet, innocent Austin possibly have to hide? If he's hiding it from me, it has to be something BIG. But for now, I guess I'll have to wait to find out. Not going to lie, my curiosity is getting the better of me.

I go back into the store.

"What was that about?" Trish asks.

"Nothing, just... Austin. I think he's hiding something. Something big." I answer. Shoot, why would I tell Trish that?

"Then we're going to find out," Trish responds. Man, I hate it when she does that.

"No, you are. I'm not spying on Austin,"

"Suit yourself. But your curiosity will only gnaw your insides out," Trish tries to persuade me. I am pretty curious...

"When are we going?" I say without thinking. That's what Trish does to me. She tries to get me to do something I don't want to do, but I always end up agreeing. What did I just get myself into?

"How about ..." she starts, and then she notices that Austin had just passed and was headed toward the bus stop. "Right now! Let's go!" she finishes, dragging me by the arm to where Austin was going. I have a feeling this won't end well. I always get this feeling. And then it always ends up going horribly, just like I would think!

What have I done?

Okay, so that's done. How'd you like the first chapter? Don't forget to review and PM me your thoughts, ideas, suggestions, anything. Oh, and the first person to guess the episode that the little flashback is from gets a shout out next chapter. and no cheating! So close out of Google. Come on!

Now time for our random fact of the day! (Yes this is a thing. Can't remember where I got it from. I think AllAmericanSlurp, but she doesn't do it very often)

My neighbor, who is four, goes to the park and says she wants to go on the Monkey Jars (Instead of Monkey Bars) :D It's so cute!

Well, see you next chapter!

Tschau! (German for bye, pronounced like chow)
