Author's note: This is my very first fanfic, so yeah, be nice! (I don't mind any constructive criticism though! :))

Oh, right...almost forgot.

Disclaimer: I do not own Austin & Ally, or any brand associated with it. Only the story line is mine!

Austin has been getting weird messages in his P.O box recently. At first he brushes them off, because he's Austin Moon, and it's not unusual to receive strange messages from certain fan girls. He decides not to show his friends, because why would he make them worry about something trivial?

But then the messages increase in creepiness and start to show in other places: at the recording studio, when he's eating at Shredder's, even at his own house's mailbox. He starts to worry, but still refuses to tell anyone else. Besides, what bad can possibly come out from this? He concludes that it's just a bit of fun.

He's currently at Shredder's with Dez when the waitress taps his shoulder.

"More messages for you, Austin." She hands him a pile of mail.

"Thanks." he smiles, and she smiles back before going off to serve another customer.

He looks through the pile of messages, most of them are sweet, but then he sees the familiar purple envelope.

This one is by far the creepiest. It's decorated with pink hearts.

"You'll be mine tonight. We'll be together, I promise you Austin :) xx –TT"

Austin gulps. Tonight? But he has a date with Ally tonight. He decides to be extra careful. Not that he thinks anything will happen. But just in case.

Dez notices Austin deep in his thoughts. "Austin, what's up?" he asks.

"It's nothing, Dez, just the usual messages from my fans!" Austin replies a bit too cheerfully. Luckily Dez doesn't notice.

"Oh, okay…" silence from Dez before he speaks again, "are you gonna eat that?" He's referring to the fries on Austin's plate. Austin shrugs and lets Dez have the rest.

Soon Dez has to leave. He mentions something about feeding his pet llama and seeing Carrie. They do their signature "what up" handshake before Dez leaves.

Austin is left to ponder about the letter. There was one thing on that letter that stood out from the rest. This letter had a signage – the letters TT surrounded by a yellow heart. Who the heck was TT? He racks his brains trying to figure out if anyone might have TT as their initials, but eventually gives up. He looks at the time and realises he has just over an hour before his date with Ally. He should definitely get ready, and make sure he actually arrives on time for this date, unlike the last two dates. He's been meaning to make it up to Ally.

He walks home, still thinking about the message. Surely this person wasn't serious? Maybe he was over-thinking it.

It starts to rain and Austin groans because he forgot to bring an umbrella with him. He's not even halfway home and he curses the sky for not waiting another 15 minutes to pour. Now his hair will be ruined.

Suddenly he doesn't feel any more rain on his head. But no, it hasn't stopped raining like Austin assumes. An umbrella is placed on top of him. He looks at who has offered this kind gesture, realising it's the waitress from before.

"Hey," she says, "I realised you were getting drenched in the rain and thought you'd need an umbrella."

"Hah, yeah, thanks...?"

"Tilly." she smiles.

"Thanks, Tilly. You live around here too?"

"I sure do!"

"That's cool, though I've never seen you around before." He thinks it probably because he's never really paid attention to people other than his best friends. He can't even remember his neighbour's name. Was it Ronny? Rikey? Rocky? Oh well…

"Oh yeah, I recently moved." Austin brings his attention back to Tilly, noticing a flicker in her eye, but isn't sure what it is. He shrugs.

"Ah, well, I hope you're enjoying it here."

His phone beeps. It's a text from Ally, telling him she's looking forward to the date. He smiles at her loving message. Then he hears Tilly mutter something incoherent.

"Sorry. What did you say?" He begins to type a message back to Ally.

"I said, I will enjoy it now that you're here..." Austin looks up to see Tilly isn't standing in front of him anymore.

"Wait, what-" he feels an ache on the back of his head and his world turns black before he can fully express his confusion.

What happened to being 'extra careful'?

Ally's waiting at the front of the cinemas, getting slightly annoyed. Austin's 15 minutes late and he hasn't been replying to her messages. Austin was late for their previous dates as well, but not to this extent. She decides to text Dez to see what's going on.

Ally: Dez, have you seen Austin?

Dez: Isn't he with u? The last time I saw him, he was at Shredder's, but that was 2 hrs ago. And I left b4 him to see Carrie and feed my llama so sorry I can't help u there :-(

Well, Dez wasn't of help then. And there's no point asking Trish because she knew she was on a date with Jace.

Ally begins to type something else to Austin (something about getting to the cinema now or else there'd be no kisses from her), when finally a reply comes.

Austin: Hi Dawson. This is not Austin. Your boyfriend's with me ;)

What in the world...?

Ally: Who the heck is this?
Austin: It's not important who it is, what's important is that Austin is mine, and you need to break up with him
Ally: Excuse me!?

How dare this person demand she break up with her boyfriend?

Austin: You've humiliated me over the years, and this time I'm taking what's yours. Break up with him, or I hurt him.

Humiliated? Who could she have possibly humiliated?

Ally: Don't you dare hurt him!
Austin: I won't if u do what I say :-) I'll give u a chance to figure out who I am, and then I'll tell u where u'll find Austin.
Austin: ur only clue – check Austin's bedside drawers

Ally sighs, before leaving the cinema, and making her way to Austin's house.

When she finally gets there, she uses the key Austin gave her to open the door. As usual, Austin's parents aren't home. Ally rushes to Austin's bedroom and opens the drawers on his bedside table. She takes out the contents, analysing the pile of purple envelopes.

She picks up the first letter: "Your in my site ever since I first laid my eyes on you xx"

Well that was somewhat disturbing. And not to mention the grammar was atrocious. It's 'you're', not 'your'! And it's 'sight'- oops, she was getting off track. As she goes through the rest of the letters, her face turns paler. Why did Austin not tell her about these?

It was obvious by looking at the handwriting that they all came from the same person. She reads through the letters again, and a few of them come to her attention.

"Don't sticks with butterflies, Austin. Ladybugs are much prettier, and they live for longer too ;)"

"Why be with boring brunette Ally when you've got this blonde beauty right here? xx"

Why didn't she work it out sooner? She knew who had taken Austin. She sends the mystery girl back a text message.

Ally: Why are you doing this, Tilly?
Austin: I see you've figured out who I am ;)
Austin: Here's a reward~

The next text from Austin's phone is a photo of Austin tied to a chair, blindfolded. He looks like he's being held in some type of old building. Ally gasps. How is this even happening?

A loud ringtone suddenly breaks her out of her thoughts. Austin's ring tone.

88888888888888

Austin wakes up to a dull ache in the back of his head. He groans and tries to touch it, until he realises his arms won't move. He opens his eyes only to realise there's some sort of cloth obstructing his view. What the fu-

"I see you're awake," a familiar voice speaks up.

"Tilly!?"

Said girl giggles at his surprise. "I'm glad you still remember my name."

"Tilly, what are you doing? Why am I here?" Austin starts to pulls at his bonds. He starts to realise the level of trouble he's in; he can't even see his captor!

"Well, you know those purple envelopes you've been receiving? They're from me, Tilly Thompson!" she squeals.

Oh, so that's what TT stood for.

"They're from you!? How did you know where to put them?"

Tilly clicks her tongue. "I'm been following you around, silly! It's not hard to spot your glorious blond hair!"

Austin stares hopelessly in the direction of the voice, dumbfounded. "But why-"

"Don't worry, Austy, you'll get your answers soon." Austin wants to vomit at the sound of 'Austy'. No one calls him that, not even Ally.

"All you need to know now is that…Ally will be gone tonight, and you'll be mine forever. You know, like I said in the letter!" She exclaims excitedly. Austin's eyes widen behind the blindfold, and he doesn't know whether to laugh or cry. This is ridiculous. Wait, what does she mean by Ally being 'gone'?

"But first…" He hears her voice as she comes closer, and feels the blindfold being pulled off. He squints as bright light hits his corneas. As he adjusts his eyesight, Austin meets the face of Tilly and her brown orbs, and almost falls out of his chair at how close she is.

"…let me give you a kiss!" she sings – horribly, Austin would have added if he wasn't focussing on trying to move his face away from the oncoming kiss. But he can't go anywhere as Tilly grabs his face, and he has no choice but to let her kiss him. He squeezes his eyes shut, and to his relief, she only kisses his cheek. He cringes at the touch of her lips on his face. She shows him through a small mirror the lipstick stain on his cheek. Eww. He can't wait to clean that off. Well, that is if he gets out of here.

"Kissing your lips is for later." She winks at him. Austin, for the second time today, wants to vomit. Only Ally can touch his lips.

"We'll see about that." He hears Tilly mutter. Oops, did he say that out loud?

Tilly walks away, and reaches into her pocket, pulling out a familiar phone, and dials someone. Hang on, that phone belongs to him! He's too far away to hear who's on the other line.

"Nope, it's not Austin. Guess again."

Tilly smirks. "Uh-huh, that's right. It's Tilly. You still remember me, huh?"

What, who was she talking to?

"Uh, uh, uh. You don't get to give me orders. I'm the one who has your boyfriend." Wait, is that who he thinks it is?

Tilly's next words confirm his suspicions. "Ooh don't get feisty with me, Dawson. You still have to break up with Austin." What? No way was she making his Ally break up with him.

"Ally, don't listen to her! I love-" Tilly walks over and clamps her hand over his mouth, not letting him finish. At least he can now hear what Ally has to say.

"And what if I don't?" He hears his girl's voice.

"Hmm...I could just hurt Austy here..."

"Don't you dare! Austin, hold on, I'm going to save you!" Austin just hopes Ally has a plan up her sleeve.

"After this call, I'll text you the address and time we'll meet...I want you to come here, and break up with him face-to-face. Don't you dare call the police. I'll hurt him if I have to." Austin suddenly remembers Tilly mentioning about Ally being 'gone' tonight.

As Tilly accidentally loosens her hand's grip on his mouth, he takes the chance to warn her. "Ally, don't listen to her! It's-"

Tilly presses the end call button before he can completely warn her of Tilly's trap.

"No more talking from you, Austy." Tilly widely grins, exposing all her teeth. And Austin thinks – as Tilly puts a strip of duct tape on his lips– that even the Cheshire cat isn't as scary as she is.
