So I'm just gonna skip the ten years they spend together... also, Lilli's "illusion" powers slow her aging down, she's actually 25/26, but she looks like 20/21... just go with it...

1962…

(10 years later…)

Raven and Lillian sat at a table, watching as Charles flirted with a woman. The woman had one green, one blue eye- heterochromia, a mutation.

Lillian smirked, amused, as her brother touched his forehead before ordering a drink for them both. Of course, using her telepathy, she was listening in.

"How's his flirting coming along?" Raven whispered, sitting next to Lillian on a stool in a short black dress with a low cut, her blonde hair below her shoulders in curls.

"Well if you count telling the girl you're hoping to hook up with that she's got 'a groovy mutation' and that she is 'a mutant' as flirting then I'd say it's coming along perfectly," Lilli grinned, crossing her legs, she was wearing black skinny jeans, a purple turtle neck and a pair of burgundy leather Doc Martins.

"Why don't you give him some tips?" Raven suggested, grinning at her sister.

"It might be a bit late to save this relationship," Lilli grinned, touching her temple.

'Need some help Charles?' Lilli asked, her voice coming through clearly in Charles' head.

'Don't mock me, little sister, I've got this,' Charles replied, glancing at his siblings at their table.

'Okay, okay, good luck with that.'

"What did he say?" Raven questioned.

"That 'he's got this', oh great," Lilli groaned.

"What?"

"They're gonna see how his mutation seducing is in the morning," Lilli laughed.

"That's it," Raven said, grabbing her purse and standing up, Lilli wiped the grin off her face and shot up, grabbing her satchel as she went.

"Mutant and proud," Amy was saying, as she and Charles clinked glasses.

Raven and Lilli exchanged a glance.

"Hi," Charles smiled at his sisters.

"Hi, guess we have to buy our own drinks, huh," Raven hinted, standing next to Charles and Lilli.

"I'm sorry," Charles apologised, he turned to the barista, "one cola and one lemonade please."

"Charles here was just telling me I'm just like one of the first sea creatures that grew legs," Amy emphasised.

"Tiny bit sexier," Charles smirked, "I'm sorry, these are my sisters, Lilli and Raven."

He pointed to each in turn.

"What do you two study?" Amy inquired, smiling at the sisters.

"Waitressing," Raven answered, raising an eyebrow, Amy turned to Lillian.

"Teaching," Lilli responded, beaming at Amy and shaking her hand.

Raven looked at Amy's eyes for a second before her left eye turned gold, Lilli smirked and quickly changed her right eye from blue to grey using her illusions.

"Oh look," Amy grinned, "you both have heterochromia too!"

"Sorry what?" Charles questioned, confused.

"Well look at their eyes."

Charles turned to look at his sisters, who smiled at him with their mismatching eyes, his expression hardened.

Charles stood up, "Right, Lilli, Raven, get your coats please," he dropped £5 on the table next to the two drinks.

"Neither of you talk to me," Charles demanded as they walked out of Oxford, "you both did that on purpose."

"We did not!" Raven dignified, following her brother and sister out, shrugging on her coat.

"Why on earth would we, Charles?" Lilli asked, pulling on her leather jacket.

"You know neither of us can always control our mutations!" Raven added.

"You both seem to be doing a perfectly good job at it now!" Charles stated as the trio walked up the lane.

"Mutant and proud," Raven mocked, pulling a face, "or is that only with pretty mutations or invisible ones like both of yours?"

"Raven that is not true!" Lilli exclaimed, looking at her sister fiercely, her chestnut and auburn ringlets bouncing around as they walked back home.

"Lilli's right, you're being ridiculous," Charles agreed, "look I don't mean to sound like an old fart-."

"Which you are," Lillian and Raven said in unison.

"Yeah, sometimes; but we've talked about this, guys, a small slip up is one thing, but a big one does not bear thinking about," Charles warned, his sisters' faces falling.

Raven stood in the bathroom brushing her teeth, wrapped in a white dressing gown in her normal state of blue skin and red hair.

"Mutant and proud," Raven repeated, brushing her teeth, "mutant and proud?!"

Lilli looked up from where she was lying on the sofa reading Charles' book on mutation, she sighed at Raven as she heard her sigh as well.

"If only," Raven grimaced, looking at her reflection.

She walked out of the bathroom, and looked at her brother where he was sitting at his desk writing, "Would you date me?"

"Course I would," Charles replied instantly, "any young man would be lucky to have you, you're stunning."

"Looking like this?"

"Raven, how many times must I tell you? You're beautiful no matter if you're pink or blue," Lilli exhaled.

"But would you, Charles?"

Charles looked up, "I- you- what? Blue?"

Charles felt Lilli's cold glare and continued, "You and Lilli are my oldest friends."

"We're your only friends," Raven rolled her eyes and Lilli snorted and laughed.

Charles' lips quirked, "Thank you for that."

Raven got impatient, "Well?"

"I am incapable of thinking of you in that way," Charles closed his book, "I feel responsible for you, anything else would just feel… wrong."

Charles sat on the sofa next to Lilli and she readjusted to sit in the crook of his arm and lay on him, Raven walked over, "What if you didn't know me?"

"I do know you," Charles grinned.

"Unfortunately for us," Lilli smirked.

"God, I don't know what's gotten into you lately," Charles shook his head, "so concerned with your looks."

Raven sighed in defeat and walked over to the siblings, lying in the space between the sofa and Lilli's waist, resting her head on her sisters stomach.

"I'm sleepy, will you read to me," Raven asked.

"I can't I have my thesis coming up I have to study."

"Ugh, fine, read me that," Raven closed her eyes, "your thesis always sends me right off."

Charles sent a defeated look down at Lilli and she laughed before closing her eyes and Charles started.

"To homotheansalentis his mutant cousin homosapien was an aberration, peaceful cohabitation if ever it existed, was short lived; records show that the arrival of the mutated human species ' region was immediately followed by the extinction of their less evolved kin…"

Lilli's mind wandered as thoughts of those around her flooded her mind, though it didn't bother her she'd learned to block them out with Charles' help.

I apologise in advance in case, like, half of the words in that last paragraph are spelt wrong... but you try to spell them... follow, fave, review?
