On the day of Allison's 17th Birthday she finished getting ready as Kate walked into her room. 

"Hey, listen... I couldn't wait, so I'm giving you your birthday present early." Kate said, handing over a box to her, and Allison opened it to find the show's necklace, causing her to smile. After turning over Kate's body, I really should ask Stilinski for this back... 

"I love it!" Allison said with a bright smile as she gave Kate a quickly hug before pulling away and taking it out of its box to put it on. 

"It's a family heirloom. And, you know me-- I hate and loathe all sentimental crap-- but that? Well, look at the symbol in the middle of the pendant. See that?" She asked and Allison nodded. 

"Yeah..." 

"You ever wanna learn a little something about your family? Look it up." Kate said and Allison looked at her. 

"You're gonna make me work for it?" 

"Some mysteries... are worth the effort." Kate said and Allison laughed slightly. 

"Thanks." She said and Kate nodded. 

"Bye!" Kate said before leaving the room as Allison put around her neck, before grabbing her bag and leaving.

When she opened her locker Allison smiled as Balloons popped out. She grabbed the card from inside, it was signed by Lydia making her smile more. 

"Is today your birthday?" She heard and turned to see Stiles (surprisingly but happily). 

"Yes. I don't know how Lydia found out though, I didn't even tell her." She said with a thoughtful frown. 

"Why wouldn't you tell me?" He asked her, also frowning. 

"Because... I'm seventeen..." She said with a slight grimace. 

"You're seventeen?" He asked in surprise. 

"That's the reaction I'm trying to avoid." She sighed, turning and grabbing the Balloons before stuffing them back into her locker. 

"Why? I mean, I-I totally get it. Uh, you had to repeat a year because of all the moving around, right?" He asked her and she smiled before kissing him. "...What was that for?" He asked, confused. 

"For literally being the first person to ever make the correct assumption. Everybody's always like, "What, did you get held back?" "Did you ride the short bus?" Uh, "Did you have a baby?"" She listed off, getting an appalled look in return. 

"That's what you hear on your birthday?" 

"Oh, yeah. All day long." She said, nodding. 

"Then... what if we got out of here?" He asked her and she looked at him, amused. 

"Skip class?" 

"Yeah! The whole day." He said and she looked at him in a bit of amusement. 

"Well, you're asking someone who's never skipped one class to bail out the entire day, and I don't--" 

"No, see, that's perfect! If you get caught, they'll go easy on you." Stiles said and she sighed. 

"Well, what if you get caught?" 

"Let's... try not to think about that. My dad's at work, so we can go to my house." He said before taking her hand and leading her out of the school. 

"Okay. But first I want to see Lydia, she's not at school today. I think last night had her freaked out." Allison said and Stiles nodded. 

When they got to the parking lot they got into Stiles's jeep, leaving Allison's car behind. 

"Uh, maybe this is a bad idea... And my mom would kill me if he found out..." Allison said, not even joking. 

"Do you always follow your mom's rules?" He asked her and she looked at him. 

"That's right, you haven't met my mother yet. Yes. I follow her rules, she's crazy. My dad's not so much." Allison told him and he nodded. 

"Well that's something at least." Stiles said before starting the jeep and pulling out of the parking lot.

When they got to the Martin house Stiles stayed in the car as Allison went up to see the girl, who was strung out on pills. Allison went up to her room and the girl turned to her. 

"Hey Ali..." Lydia muttered. 

"Hey, Lyds. You okay?" Allison asked her. 

"I'm fantastic." Lydia said back. 

"Lydia, what did you see?" Allison asked her and Lydia's face went blank with a scared mixed in. 

"I saw..." 

"Lydia, what did you see?" Allison asked her again. 

"Something..." 

"Something... like a mountain lion?" Allison asked and Lydia slowly nodded. 

"A mountain lion..." 

"Are you sure you saw a mountain lion, or are you just saying that because that's what the police told you?" She asked and Lydia answered, dazed. 

"A mountain lion..." 

"What's this?" Allison asked, holding up Lydia's stuffed Giraffe. 

"A mountain lion..." 

"Okay..." Allison said with a sigh before Lydia passed out. "Okay then." She muttered, moving the girl onto the bed before grabbing Lydia's phone and started deleting every photo and video that Lydia had of Peter from the night before, off the girls's phone. 

When she was done she quickly left the girls room and then the house all together.

When they got to Stiles's house and up to his room Allison couldn't help but smile as she looked around at it, happy to finally see the famous Stiles bedroom. 

"...You're still not okay with this, are you?" Stiles asked her and she shrugged. 

"I just feel like I need an alibi." 

"Well, if we get caught, I'll just say it was my fault." He told her and she smiled and shook her head. 

"You don't need to take the blame for me. It was my choice, too." 

"Oh, good! 'Cause if we get caught, I'm totally gonna blame you." Stiles told her and she laughed. 

"Oh, really?" She asked him and he nodded. 

"Hell yeah! And they'd believe me. You know, a totally hot girl like you asks a nerdy guy like me to skip the day with her? Like I'm gonna say no!" He said and she scoffed a laugh of amusement. 

"So, you throw me under the bus, just like that?" 

"Yeah! Throw, push, shove..." He said, shrugging. 

"And what if I decide to drag you down with me?" She asked, walking closer to him as she pulled him in closer to her. 

"I'd just yell for help." 

"Well, what if I did this?" She asked, kissing him. 

"I'd scream for help." He shrugged. 

"And if I did this?" She asked before full on kissing him. 

"I'd beg for mercy." He said and she giggled before kissing him again, a lot more this time. 

"You're really adorable when you're like this, you know that?" She asked him and he smiled at her. 

"Yeah?" 

"Yeah." She nodded with a smile, kissing him again. 

The two of them proceeded to fall onto his bed and make out- nothing more. 

As the day passed on they moved on from kissing to watching FRIENDS and then just talking when Stilinski came into the room. 

"Hello." Stilinski said to Allison. 

"Hi. I don't think we've met yet. I'm Allison." She said, standing up and shaking the man's hand. 

"Hello Allison. It's nice to meet you." The man said before looking at his son, "Please tell me I'm gonna hear good news at this parent-teacher thing tonight." 

"...Depends on how you define "good news."" Stiles said hesitantly as Allison giggled. 

"I define it as you getting straight-A's with no behavioral issues." Stilinski said, unamused. 

"...You might wanna rethink that definition." Stiles sighed and the man sighed before nodding. 

"Enough said." With that Stilinski left. Allison smiled as she went to sit next to Stiles again, before getting an idea and moving to straddle the boy, as he started blushing. 

"So, being completely honest? This was kind of a perfect birthday." She told him with a smile. 

"Good. I'd know if you were lying, anyway." He told her and she looked at him, amused. 

"Oh, really?" 

"You have a tell. You touch your eyebrow right here." He told her and she looked at him, amused. 

"Let's see if you can figure out if I'm lying now. I wish that I could spend the rest of the day with you." She told him. 

"The rest of the day?" 

"Well, the rest of the night." She said, giving him a slightly suggestive look, that made him blush a bit. 

"With me?" He asked her and she nodded. 

"Oh crap." Allison muttered with wide eyes. 

"What?" he asked, frowning. 

"The parent teacher confrense. I'm willing to bet someone is going to mention I wasn't at school today, my parents are going to kill me." Allison said, getting up, "I completely forgot." 

"Hey, it's okay, come on, I'll drive you to the school." He told her and she nodded with a sigh.

When they got to the school they got out of the jeep to find Allison's parents quickly going towards them. 

"Uh oh." Allison muttered. 

"Crap." Stiles said, seeing his own father coming towards them. 

"Let's go." Argent told her and she sighed. 

"So when we spoke before it slipped your mind to tell me you skipped today?" Stilinski asked his son who grimaced slightly. 

"I was kind of hoping you wouldn't find out." Stiles sighed. 

"It's not his fault. It's my birthday, and we were--" Allison tried to explain to them, only for a scream to break through the air. 

"Allison. In the car." Argent told her, but they were quickly separated. 

Allison saw it before most did, and she quickly got on top of her own car to get away from it. Soon enough came the gun shots and then the panic went down, and everyone quickly left.

When they got home Allison got into a fight with her mother about boys and school and stuff, and then was sent to her room, but thankfully wasn't in that much trouble due to this being the first time she'd done this, and Kate being there to get her out of it. And also flashing Chris a few tears and big puppy eyes- daddy's girl trick, he caved very fast, and let her off with a warning.
