"I give up! Who invented logarithms anyway?" Isaac demanded, throwing his books on the floor.

"John Napier." Lydia replied, flouncing into the room and settling on the couch. Isaac sighed, throwing his head against the cushion.

"How do you even know these things?" he demanded, frustrated.

"It interests me" she shrugged, licking the ice cream off her spoon.

"Is there anything that doesn't interest you?" he asked, and she thought about it for a moment.

"No."

Isaac rolled his eyes.

"Need some help?" she asked.

"Hmm, fail algebra or get help from the smartest girl in the whole school. That is a hard one…" Isaac laughed.

"Don't be clever. I'm the clever one, you're the potato one." she said, and came to sit on the ground beside him.

"Whovian" he muttered under his breath.

"Takes one to know one!" she chirped, picking up his discarded books and preparing to explain the the quadratic equation.

When they finished, Isaac felt like he had actually learned something-which was amazing because he had been in Mrs. Mitchell's class for almost a full year and hadn't absorbed anything. He leaned his head against the couch again, and stared at his completed worksheet, awestruck.

"You are amazing"

"I know" she replied, grinning. "I'll be back tomorrow, kay?"

Isaac's head snapped up, "Wait tomorrow, you mean, you're going to help me again?"

Lydia laughed at him, "Don't you want to pass?" she asked, throwing her bag over her shoulder and walking towards the door.

"God I love you! You are amazing; seriously, Stiles had the right idea about you!" he exclaimed as she exited.

"See you tomorrow, sweetheart!" she called back as the door swung closed.

Isaac sat back down on the couch, and felt a strange urge to watch Doctor Who. He thanked his lucky stars that Stiles had partial control of the DVR. This meant there were a bunch of re-runs already taped.

He lay there a while watching David Tenant episodes happily.

"God, Stiles is rubbing off on you" Derek said, laughing when he came in, and sat down on the couch next to Isaac.

"It's a good show" Isaac replied, shrugging.

"Wait, who's this guy; I thought it was a different one?" Derek asked confused, gesturing towards the brunette brandishing the screwdriver on the television.

"He changes faces… you know what, just let Stiles explain it to you, he'll love it."

stiles and isaac hadn't always gotten along swimmingly. the other teen was often too outspoken and loud for isaac's taste in the beginning but after a while he started to grow on him. dragging him into the world of internet fandoms, and the admeration for british television shows.

Derek nodded. "Why was Lydia here?"

Isaac shrugged because he wasn't exactly sure himself.

"Don't know, she might have been here to steal your ice cream but she ended up helping me do my homework."

"How'd that go?" Derek asked. Isaac smiled because Derek was so much like Cam, it was crazy. He was tough on the outside and ridiculously sweet on the inside; he wasn't sure Derek knew it, but he was really thankful to have him. Derek was concerned about him, his grades, and his love life. Derek went to all his lacrosse games and bought him new clothes, and it made Isaac feel almost like he had a family again.

life had gotten easier since derek became his guardian. They were, well they weren't really a family but they were better than what isaac had before. Derek's house was home and him and Stiles had become like brothers. It was weird at first, Derek being there all the time, someone actually caring about him but sometime in the last year it had become normal.

as normal as it was to walk into the kitchen and see stiles and derek making out over dinner. which okay in the beginning that hadnt been normal either but now it was kind of sweet. almost sickeningly at this point but they were perfect.

"She's brilliant, like, astoundingly brilliant and I actually understood what we were doing. She's coming back tomorrow." Isaac said grinning, and Derek laughed, clapping him on the back.

"Good for you, pup." he said, checking his watch and standing up. "I have to go get Stiles from work or he'll never talk to me again."

Isaac laughed, "Only you would think that was a bad thing"

Derek shrugged, grabbed his coat, and walked out the door.

It didn't occur to Isaac until later that Derek might not have been congratulating him on getting his math homework done, but he shrugged it off. It didn't even matter if he liked Lydia (which he didn't) because she was hung up on Jackson from, like, now until forever. Even though the guy had pulled a dick move and left.

When he got home from school the next day, Lydia was sitting on the couch reading an old book, probably written in Latin (or something else he wouldn't understand).

"Hey," he said smiling. "I um… actually didn't get assigned any math homework today." He sat on the couch next to her. She shrugged.

"How are you doing in English?" she asked, and he cringed.

"Macbeth is kicking my ass."

She grinned, shutting her book and setting it on the table. "Well, let's fix that."

She pulled out her copy and started explaining their assignments. When they were finished three hours later, Isaac had completed his essay, started his chem lab report that wasn't due till next week, and finished his econ essay.

"God, how did I ever do this without you?" he asked, laughing.

"You didn't," she replied, packing up her things. He nodded.

"Oh yeah." he said, still laughing a bit. "You uh, you wanna stay for dinner? I was just going to get Chinese take away." He gestured to the kitchen. Lydia made a face like she was thinking about it, before plopping down on the couch and grabbing the remote.

"Only if I get to pick the movie."

"Deal" he responded immediately, crossing the room to grab the take away menu and bring it back to her.

"Alright, pick food I'm starving."

She scrunched up her face in a way that shouldn't be so freaking adorable, but it totally was.

"Uh, Lo Mein noodles and an egg roll." She handed the menu back to him. After he called in the order, he sat back down on the couch.

"What movie are we watching?" he asked, trying to judge from the trailers before the menu popped up, and failing.

"The Avengers" she said happily. He grinned at her.

"Could you possibly get any better?" he asked, and she stared at him blankly.

"You're gorgeous, smart, funny, and low and behold, apparently have an appreciation for Marvel superheroes and chocolate ice cream." he said, grinning and staring at the opening credits as he babbled. "It's like they took everything good in the world and put it into you."

Isaac watched the movie with wide eyes; he had seen it, like, 12 times already but it never got old. And because he was staring at the screen, he didn't see Lydia staring at him like he had grown another head.

Because, why would she? He was sure people complimented her all the time; she was Lydia Martin, after all.

Except that, nobody ever said things that nice to her. They said things like, "Pretty dress" or "I like your shoes!"

Nobody but Stiles had ever complimented her for anything but her looks.

They watched the movie in near silence, with the occasional laughing, or Lydia pointing out potholes and places where the movie didn't match the comics. About halfway through, someone knocked on the door.

"Must be the Chinese" Isaac reasoned, standing up and grabbed some money from under the wolf Stiles had put in the kitchen.

"Oh my god, that's a lot of noodles!" He exclaimed, returning to the couch with the take out container and chopsticks. He was right-they had given them a giant container of Lo Mein which made Lydia grin.

"Yum!" she said, taking the chopsticks to the noodles. Isaac tried to stop a giggle, she looked adorable.

It was in that moment that Isaac realized he had a crush on Lydia Martin.
