Full Summary:

She was afraid; afraid of her own power- No, her curse. She wished she had her brother's power, or any other power in fact. Anything but what she had. So when Charles and Erik request her help, Sage could only hope to say no. But because her brother felt the opposite way, she allowed herself to be dragged in a situation where she never expected to have ended up in: A war between mutants and a load crap of drama.

It's all Cade's fault for getting her into this. Yet again, it was also her fault for following her twin everywhere.

An X-Men: First Class Fanfic - Alex/OC

Chapter 1 - To Win the Bet

"So where'd they go now?" Sean asked Raven, who was idly playing with the ends of her hair. It was about 4 in the afternoon and Charles and Erik disappeared off somewhere after dropping off the last recruit; Alex.

Alex had been at the faciliity for about an hour and he was already feeling exhausted with the amount of socializing he's done. It wasn't common for him to constantly socialize with people around his age, much let alone the people who didn't guard his cell. Although he found new company and freedom refreshing, he still felt the need to keep to himself at times. He supposed it was just the effect he had gotten after being in solidarity confinement for 5 years.

The girl leaned back in her chair, "They went to go get the last pair of recruits." she sighed.

"There's more of us?" Sean asked, still trying to overcome the fact that there were others like him. Raven looked at the brow-raised teenager and nodded.

"You don't seem to sound so happy about it." Darwin pointed to Raven, before taking a sip from his soda. Angel, the stripper, was sat next to Darwin on a white love seat identical to the rest of the seats the others were sitting on. Alex, the newcomer, felt quite comfortable in his seat, savoring the comfort of the plush cushions. It was far more better than the hard steel metal he was left with back in his cell.

Raven threw her hands up, "It's not that I'm not happy. Don't get me wrong, I totally am. It's just that everything is taking so long. They're getting 2 more people. At this rate, they'll be back by tomorrow or by midnight. Like I said earlier, we don't reveal our powers until we're all here. I'm just impatient." She pouted. Alex thought that revealing their powers after every last recruit arrived was a bit silly. But then again, waiting to witness everyone's powers was something he didn't have the patience for. Despite that, he was curious about everyone else's powers as well. Alex couldn't blame Raven for being impatient though. He too, was getting just a little restless at how long they'd have to wait for everyone. Alex was getting a bit bored. "They didn't even get the chance to tell me anything about who they're getting next."

Hank, who Alex found easy to pick on due to his demeanor and typical nerd-like look, shifted in seat and said, "Well actually, it won't take that long to get the two of them. They're not that that far away. I give them an estimated time of an hour or three."

"How's that even possible?" Angel asked, "Unless the first person they get can teleport them to places or whatever."

"Well no, but they are only going to one place. The last two recruits are together." Alex raised his eyebrows.

"As in…They're a mutant couple?" asked Sean, a hint of amusement in his tone.

Hank shook his head, "No, no. They're siblings. Better yet…twins." Everyone, including Alex, let out a bunch of Oh's.

"Twins?" Alex clarified.

Hank nodded, "Charles said that they're both really powerful."

"Do you know what they do?" Hank shook his head.

"That's dope, man." Sean said. "Twins…Are they both girls!?" His eyes lighting up. Alex shook his head at the ridicule of his new friend. Although he might not admit it, he was starting to grow fond of the people around him. Even if he just met them over an hour or two ago.

Hank only shrugged, "I don't recall much about what they said. But I only know their names, so I'm guessing their both boys." Sean slumped back in his seat in slight disappointment.

"What are their names?" asked Darwin.

"Er- Se- no. Oh! Sage and Cade."

"Sage and Cade?" Alex repeated, "Oh, they're both definitely boys." Sean groaned.

"Hey, Sage can be a girl name too you know!" Raven argued.

Alex and Sean glanced at each other with doubt on their faces. Smirking, they shook their heads. "Right." Sean said sarcastically.

"I'm serious!"

"Well then, have you ever met a girl name Sage?" Alex retorted.

"Actually…Well-no." but she quickly added, "But I bet there is a girl named Sage! I bet this new Sage recruit is a girl, and Cade's a boy!"

"Come on, Hank. You're the smart brainiac one here, what are the chances?" Angel asked.

"Chances of boy-girl twins? Unlikely. But considering our knowledge of the situation, it's a 50/50 chance." He replied.

"Ha! See!" Sean exclaimed.

"He said 50/50, Sean. Which means there's a likely chance that we're right too." Raven pointed to which Sean waved off. "I so bet we're right."

Sean took his hand and cupped his ear, "Is that a bet I hear?" He grinned.

"And how do you know Cade isn't the girl and Sage is?" Darwin pointed out.

"Cade doesn't seem to fit a girl." Angel replied. "Sage has somewhat of a..unisex hear to it." Sean snorted.

"Well I bet I'm right." Raven announced.

"You're on." challenged Sean, "I bet the twins are both guys-"

"-And I bet that ones a boy and the other is a girl. Sage is the girl, and Cade's the guy. Loser gets no dessert for dinner."

"That's it?" Alex asked in disbelief, wondering why the girl would wage so little.

Raven nodded, "You haven't tasted their dessert yet, let alone have seen it." Hank replied earnestly.

"Deal. Anyone want in?" Sean chimed.

Everyone exchanged glances, "Why not?" Angel shrugged, "I'm in. You know where I stand, Raven."

"Same." Darwin claimed, "But I'm in with the girls."

Alex clapped Sean on the shoulder, "I got your back, man." He said, feeling confident in his choice. In all honesty, Alex couldn't care about whether he would get dessert or not, all he cared was about the pride and the boasting privileges he'd get once he won.

Besides, he's hadn't had dessert in over 5 years. What more was another day to him?

"How 'bout you, Hank?" Raven asked as she turned to look at the guy beside her.

He shrugged and said, "Eh, I-I don't kno-"

"Oh come on, man. It's not a lot to lose. Don't be a wuss."

"Alex!" Raven scolded, narrowing her eyes at him to which he replied with an eye roll. He didn't get why Raven was so adamant about defending the bozo. He was just teasing, he didn't mean any harm.

"I'm not a wuss!" Hank defended, "Fine. I'm in. But I stand with the girls." Alex smirked triumphantly, looking clearly pleased with his effort.

Quickly recovering from a concerned look that she expressed towards Hank, "Looks like you got a bet, Cassidy." Raven smirked as she shook hands with the red-headed boy.

1 hour, 43 minutes, and 7.00992 seconds later.

"Charles! You're back!" Alex heard Raven exclaim as she shot out of her seat, making her way towards the doorway. Alex felt the back of Sean's hand hit his chest, trying to get Alex's attention. Alex, along with everyone else, stopped what they were doing and turned to face the doorway where they saw Charles and Erik.

"Hello, Raven. I'd like you to meet-…." Charles greeted, pulling her out of the room and closing the door.

Sean groaned, "Damn. You think they're here?"

"Most likely," Hank nodded.

Alex and the rest of the gang waited, only hearing bits and pieces of the conversation. But everyone tried to be as quiet as they could, just so they could hear more of their conversation.

"I'd like you to meet Sage and Cade..." They heard Charles introduce, making Sean extra anxious and perky.

"Hi..." An unfamiliar male voice greet. Sean and Alex sat up in their seats, smacking each other as they reached towards the winning goal of the bet. They were so gonna win this.

"And you're Sage, right?" Raven asked a little bit too loudly. "That's a really PRETTY name." Pretty? Alex thought. You're calling a guy's name pretty? Unless…The two boys started exchanging worried glances, the hope of winning starting to fade.

"Yeah, and thank you..." A sweet female voice spoke.

Alex and Sean instantly shot out of their seats before they collapsed themselves on the ground, groaning. Alex tried to tune out the high-fives and cheers that were given around the room.

They had lost the bet.

"Come on, let's introduce you to everyone else," said Raven as the door started to open, making Sean and Alex straighten up and return to their seats. "Hey guys, look who I got with me." When everyone looked their way, Alex found himself surprised. It wasn't the smug look on Raven's face, but the two people next to her. When Hank said twins, Alex was expecting some major similarities. But just glancing at the two siblings, you couldn't even tell they were twins. At this point, Alex forgot about the original bet and found the rewards of losing instead. Getting another pretty girl on the team was practically an upside. He didn't care about victory or dessert anymore. And from the looks that Sean was giving, Alex was sure he was thinking the same thing.

Alex gave them a once over, his eyes lingering a little longer on the girl. From what it looked like, they both seemed to be around his age area. Sage- or Cade, or- basically the male sibling, didn't look an ounce similar to his sister. His skin was two shades darker compared to her pinkish white skin. His hair was dark brown, give or take a few strands of copper brown hair that were scattered on his head, and kind of long. It reached down to jaw and it seemed…tousled to Alex. Kind of like bed-head, but in a neat way?

He didn't know, what did he know about hair? He was a guy that spent half of his life in solidarity confinement in prison. Kept the same hairstyle since he was born, and it was the only type of hairstyle Alex knew.

His sister on the other hand, made it seem like they were weren't twins at all. Although their eyebrows were seemingly similar when it came to being bold and full, her eyebrows were intriguingly bolder and were formed differently than her brothers. Although he usually found thick eye brows a bit weird, it worked for her nicely. Her hair was a copper shade of brown that reached further down her back compared to her brothers.

She had a pretty face too, Alex noticed.

But as he compared the both of them, they were both far apart from looking like twins. They certainly weren't identical at all, give or take one or two features. They were both slim, and if you looked really hard, their eyes were the only thing that was identical.

"Yes!" Angel cheered, high-fiving Darwin. "Ha, we win." The dark-brown haired girl rubbed into Alex and Sean's faces.

The two sibling glanced at each other confusingly before looking to Raven who sheepishly explained, "We made a bet. Our bet was whether if you guys were boy twins or boy and girl twins. My team won."

The siblings smiled and said, "We get that a lot." Them saying that in unison made everyone's head roll.

"Well let's go and introduce each other! You guys were the last to arrive, and now we're all here!" Raven replied excitedly as she tugged on both of the twins wrists forward to follow her. She then gesturing them to sit on the empty sofa that faced both of the sofas everyone was sitting on. The two siblings glanced at each other before the brother shrugged and strolled over to the empty love seat. Dropping into his seat with a relaxed smile on his face, he looked back up at his remaining standing sister and gave her reassuring smile.

Nervously smiling back, she trudged around the love seat and carefully took a seat.

Even at this point, Alex was still surprised at the unexpected new recruits. He couldn't get over the fact they weren't both boys, not that he was really complaining. She's not exactly hard on the eyes. He'd even admit that he found her innocently sexy.

By the impressed expression Sean had on his face, Alex knew he surely agreed.

The girl's eyes wandered around the room before finally setting on him. But upon seeing his attention situated on her, she quickly looked back to Charles with a neutral expression remaining on her face. Her reaction confused him, making me wonder whether she hated his attention, felt flattered, or embarrassed by it, But as she averted her eyes from him, Alex could've sworn he saw a faint blush creep on her face.

Alex couldn't help but smile.

"You guys, this is Sage" announced Raven, who pointed to the girl, "and this is Cade." then pointing to the guy. "And as you two already know, I'm Raven."

"Angel" Angel purred, a smile forming on her face as she looked at Cade up and down.

"How come I can't get her to do that?" I heard Sean mumble to Alex

"I'm Darwin." he introduced, shaking hands with both of them.

"Hank McCoy." A genuine and shy smile appearing on his face to which the twins returned.

Sean stood up, took Sage's hand and kissed it. "Sean Cassidy. 16 years old, I like fish, and pretty girls with brown hair." he hinted. Sage and Cade exchanged amused looks that said, 'Is he serious?'

Alex pulled the boy back into his seat by his shirt and said, "Alright Casanova." Sage laughed, "Get over it, man. She's out of your league, and probably older than you." Alex did a double take, his hand still fisted in Sean's shirt, "Wait, how old are you?"

"22." She answered. Huh, Alex thought, only 4 years younger than I am. But then shook the consideration out the door.

"Six years older, man." Alex pointed to Sean before letting him go.

"I can take older women."

Alex rolled his eyes and turned to the twins, "Excuse ginger's-"

"-I am not a ginger!-"

"-Sad and obvious excuse to get you in a closet, a date, or in his bed…But I'm Alex. Alex Summers." Alex introduced, a playful smile forming on his face as he looked at the twins to which Cade and Sage returned the playful smile with a smile of their own.

"Damn, if I had a sister and she was being hit on, I'd have the guy down flat by now." Darwin said.

Cade chuckled, "I don't think that's necessary."

"Really? You ain't even mad?" Sean asked, "What's your power, super emotion control?"

"I guess you could say that," laughed Cade, "But that's not what I meant. I don't think it's necessary to take any action because I don't need to worry about guys hitting on Sage."

"Well why not?" Raven asked.

"She can take care of herself."

"-I can take care of myself." The twins ended up saying together.

Alex raised an eyebrow, wondering how well she could take care of herself. "Really?" He asked, leaning back into his chair, "What's your power then?"
