Allison is not jealous.

She's not jealous over the fact that all anyone can talk about is the new girl. She's not jealous over the fact that she's been here for literally a week and is already part of their 'group.' And she definitely not jealous of the fact she's dating Stiles; which is, of course, why Allison is watching them make out against his Jeep from her car.

"Allison…Allison!" The brunette girl jumped when Lydia called her name. Allison looked at her window to see Lydia, annoyed, tapping on it. Allison grabbed her keys and got out of the car, "The bell is going to ring any minute now. What is wrong with you?"

"Nothing," Allison shook her head but couldn't help looking back over at the Jeep. The couple had pulled apart, only for Stiles to smile before kissing her again. Lydia looked over her shoulder at what Allison was staring at and made a gagging noise.

"Yewk. It is too early in the morning for me to be seeing Stilinski's tongue in some girl's mouth," Lydia rolled her eyes and looked back at her best friend. Allison was spacing out again. This time, Lydia knew why. "What is with you?" Lydia snapped her fingers in front of the girl's eyes, making Allison jump. "What are you, in love with Stiles or something?"

"What?" Allison gasped. "No. Why would you say that?"
"Because instead of being over there with Scott…" Lydia pointed at the boy, who was standing by the bike rack, holding his arms out to ask why she wasn't coming over there, "…you're over here, gazing at them like you want Cassie's head to explode."

"I just…don't like her, that's all." Allison locked her car and expected Lydia to drop the subject. "Can we get to class now?"

"Alright fine," Lydia huffed. The bell rang, making the many groups of students outside flood in. While Lydia went off to find Jackson, Allison stopped at the bike rack.

"Hey," she held onto Scott's hand but didn't kiss him like she normally did. Scott kissed her cheek instead.

"Ready to go in?" he asked sweetly. Allison started to nod when she saw the blue Jeep over Scott's shoulder. The couple was still there, giving each other one last peck—as if they hadn't done that enough—before Cassie rushed off towards the school. Stiles remained against his Jeep, watching her leave dreamily before somehow, he noticed someone watching him. Allison sucked in her breath when he met her eye; he gave her a small smile before his face turned to confusion.

Allison looked away as soon as possible, "Yeah. Let's go." She practically dragged Scott along the pavement. Today was going to be a long, long day.

"Lydia tells me you're jealous of the new girl," Jackson teased as he sat down beside Allison. The girl was lost in thought until he showed up.

"What? I am not," Allison hissed. "Why would she say that?"
"I mean, it's kind of obvious," Jackson shrugged. "I get it. You used to be the new girl, and now you're not. Someone else is."

"Oh, right," Allison hadn't even thought of that fact. She also understands how Jackson feels now; when Scott randomly became the Lacrosse team's star and Jackson got bumped down a notch. "Well, I'm not jealous,"

"Uh, huh," Jackson wiggled his eyebrows at her and nudged her side with his elbow. Allison laughed and punched his arm to get him further. The two of them are actually friends now; real friends, not friends because he's dating Lydia or wants to get back at Scott.

"Hey," someone kissing Allison cheek made Jackson roll his eyes and scoot away. Allison look over her shoulder at Scott, who smiled brightly. "I went to your locker but you weren't there."

"Oh, yeah, I just got lunch in line instead of home," Allison half-lied. She didn't go to her locker because Cassie's is right next to hers which means Stiles would be there…against it. Allison tried not to gag at the thought.

Scott sat down next to her, said hey to Jackson, who just nodded, and started talking about lacrosse practice after school. Allison ignored him; she didn't mean to, but she spotted Stiles and Cassie walking into the cafeteria. Cassie was holding his hand and her other arm was wrapped around his while they smiled; Allison really hates newly made couples. They're first date was this weekend; obviously it went well. "You're going to come, right?"

"Huh?" Allison snapped out of it. She was zoning out a lot lately. While Jackson chuckled, Scott remained clueless.

"To practice. You're coming right?"
"Oh, right," Allison looked down at her milk container. "Sure, yeah."

"Great." Allison just nodded. It wasn't that she didn't want to talk to Scott; she loves him. At least, she thinks she still loves him. It's just right now all he talks about is Lacrosse; which is good, because that means he isn't worried with pack stuff, but it also bugs the hell out of her. Allison looked to her right for Jackson to rescue her, but he was busy talking to Danny, who showed up when she spaced out.

Allison sighed, only to look up and see Cassie pulling Stiles over to the table. "Great," Allison mumbled under her breath.

"Huh?" Scott asked.
"I mean, I can't wait," Allison put on a smile and grabbed his hand. She wasn't sure whether it was because she wanted to hold his hand and reassure him, or if it's because they're coming over here and Allison wants to seem like a happy couple too; not that her and Scott aren't happy…are they?

"Hey guys," Cassie said chipperly. She was too sweet, all the time. If Erika was here right now, she would have gagged; she's the only one that understands why Allison can't stand Cassie. But then again, Allison's pretty sure Erika hates all people she doesn't know.

"Hey," Scott smiled friendly. Why is he so nice to everyone? Can't he hate her too? Allison thought to herself. She tried not to look at Stiles, who sat down beside Cassie across from the two of them.

"So I was wondering…"
"I don't think it's such a good idea," Stiles interrupted her before she even said anything else. He was looking off in space, just over Jackson's shoulder. Cassie nudged him with her arm before holding his hand.

"Oh, come on. It's a great idea,"
"What's a great idea?" Scott asked for him and Allison.

"Well, Stiles was talking about you and him rarely get to hang out one on one lately and—" while Cassie continued talking, Allison looked at the boy to see him sending Scott an apologetic look. It was true; they haven't hung out as much lately. Scott shrugged with a small smile, but Allison could tell he was hurt Stiles thought that. "—and Allison, you're really the only person I haven't gotten to know yet," Allison's eyes widened at the mention of her name.

"I'm sorry, what?" Cassie smiled over at her.
"I was thinking that maybe the guys could hang out tonight and we have a girl's night to get to know each other," Cassie suggested. Scott grinned over at Allison.

"That sounds like a great idea,"
"Yeah, Allison," Jackson agreed with a wicked grin. Allison sent him a glare, only making his grin widen. "Doesn't that sound great?"

"Just perfect," Allison hissed at him through her fake smile. Jackson winked at her and turned to talk to Danny some more. Allison looked across the table at Stiles, who was waiting for her reaction. Is she crazy, or does he seem like he doesn't want her to go? Allison could just be imagining it, but there was something in his eyes…

"So what do you think, Allison?" Cassie asked.
"You know, maybe another time," Stiles told his girlfriend. Cassie started to pout.

"Aw, why…?"
"Actually," Allison interrupted, her eyes still on Stiles. Her eyes shifted to Cassie when she felt all eyes on her: Scott's, Cassie's, Stiles', even Jackson's. "That sounds awesome, Cassie."

"Really?" Cassie's face brightened. Allison could see Stiles' jaw drop open through the corner of her eye.

"Really?" Jackson whispered in her ear. Allison ignored him with a smile.

"Yeah. We can go shopping or something,"
"Sure, sounds great," Cassie grinned, looking between Allison and Stiles. She didn't notice Stiles staring at Allison with shock, or the small smirk on Allison's lips at his reaction. "See? I told you she'd agree."

"Y-yeah," Stiles' smile shook. "So I guess it's just you and me tonight, buddy," Scott grinned at that.

"Actually," Cassie stepped in again. Allison fought the urge to groan. Stiles' eyes grew wide again, "I was thinking that maybe after we can all meet up. Maybe see a movie, all four of us?"

"I'm down for that," Scott agreed, squeezing Allison's hand. She hadn't realized she was still holding it.

"Oh, I don't think that's such a good…" Stiles started to say until he saw Allison raise her eyebrow at him. "You know what, sure," Stiles grinned at Cassie. "Sounds good to me."

"Perfect!" Cassie hopped up to her feet. "I'm gunna go get food," She put her hand on Stile's shoulder and grinned down at him. Does she ever stop smiling? Allison thought with a frown. "Come with me?" Stiles nodded, told Scott he'd be right back and just looked at Allison, who shrugged back. The couple disappeared and Allison let out a sigh she didn't know she was holding.

"I am actually jealous of you guys," Jackson smirked at Scott and Allison. "Tonight just sounds like so much fun," The grin was towards Allison, who glared. A second later, she got an idea.

"Hey, Jackson," Allison put her hand on his arm, "Why don't you and Lydia join us at the movie? You can hang out with the guys and Lydia can come with us," Jackson's eyes widened.

"What?"
"Yeah," Scott agreed with a real smile, "We don't hang out unless it's for pack stuff. This could be fun."

"Huh, yeah," Jackson puffed up his cheeks before smiling a little, "Can't. Danny and I are hanging out. Right Danny?" Jackson looked over at his best friend, who wasn't paying attention.

"We are?" Danny asked with an apple in his mouth.
"We are," Jackson patted his back before grinning over at Allison. "Sorry, kid." Allison rolled her eyes and dropped her check to her fist.

"Maybe Lydia can still come with you," Scott suggested, seeing how upset Allison seemed to be at the fact of the two of them not coming. Allison's eyes brightened.

"Yeah, maybe," she kissed Scott's cheek appreciatively. It got him to smile wider, "Thanks, Scott."

When Allison closed her locker, she was surprised to see Stiles standing next to her. "You didn't have to agree to go tonight."

"What do you mean?" Allison put on a smile. If she's going to go through with this, she's at least going to have with it. If Cassie wants to get to know her; she'll get to know her. "Don't you want me to go?" Allison tilted her head to the side. Stiles sighed.

"Allison, cut the crap," he said lowly at her. Allison's eyes widened, "I know you don't like Cassie." She sighed with relief.

"Okay, fine, I don't like her," Allison admitted. "But maybe that's because I don't really know her. Who knows? Maybe after tonight we'll be best friends and the four of us could go on double dates all the time,"

"But you hate group dates," Stiles pointed out. Allison just smiled.
"I don't hate them when they're with my new best friend," she teased. Stiles rolled his eyes as he leaned against the locker next to hers, a.k.a Cassie's. "I'll see you at practice, okay, Stiles?"

"Yeah, sure, bye." He gave her a mediocre wave goodbye before shoving his hand into his pocket and glaring at the ground. Allison smiled with victory and walked away. He really didn't want her hanging out with his girl friend tonight. Why?

"You're actually going to hang out with this bitch?" Erika gasped when she sat down across from Allison. The girl looked up from her chemistry book and smirked a little. "Why?"

"Maybe I want to get to know her," Allison shrugged. Erika rolled her eyes.

"Bull," she growled. "You just want to sabotage the date,"
"Erika," Allison sighed, even though what she said was true, "I used to hate you remember?" She pointed out, leaning forward against the chem.-table. "But then you and I hung out with Scott and Isaac at Derek's and we became friends,"

"We became friends because Scott and Isaac were too busy flirting with each other without noticing," Erika pointed out, making Allison roll her eyes. This was true; her boyfriend really was clueless sometimes. "Not that I care; I'm with Boyd now."

"Seriously?" Allison raised an eyebrow. "Can you stick to one pack member?"

"Technically I haven't had Scott," Erika teased with a gleam in her eye. Allison smiled, closing her chem. Book and putting it in her bag.

"Not gunna happen."
"Tell you what," Erika stood up too. The bell was about to ring any minute now. "When you and the She-Devil are out shopping, I'll wonder past you, bump into you accidently and you'll suggest that I stick around to shop with you guys,"

"And why would I do that?"
"Because then you and I could point out all of Stilinski's flaws to Cassie," Erika pointed out, linking her arm with Allison's. "I'd suggest you do that all on your own, but seeing how you have a girl-boner for him all of a sudden, you might not be able to think of anything." Allison sighed. She looked around the room to see if Stiles or Scott were listening. They weren't.

"Is it that obvious?"
"Tragically," Lydia stepped in, taking Allison's other arm. "And I'll be there to help."
"You will?" Allison was shocked at both girls.

"Of course," Lydia scuffed, "I have stories since the third grade to tell Little Miss Priss about golden boy over there," Lydia japed her thumb over her shoulder at Stiles. When all three girls looked at him, grabbing his attention, they gave him innocent—or not so innocent on Erika's part—smiles and waves. Stiles blushed and looked away, making Erika and Lydia laugh. "This'll be piece of cake."

"Oh, cake," Erika's eyes lit up. "Can we get cake at the mall?"

A/N: So I really, REALLY, don't like Cassie. So much that I'm forcing myself to watch First Time with Dylan O'Brien. I'm only seeing it for him, obviously; if only it wasn't her that he's with in the movie. Anyways, I thought this would be a funny crossover. It may only be a three part story.

Oh, if you can't tell, I like the idea of Allison/Stiles, though I like Jackson/Allison too, so they'll be sneaked in there from time to time.
