Catherine's POV

Being the sister of genius Charles Xavier isn't the easiest thing in the world. Always being compared to him in terms of intelligence. But it's not my fault that when he was born he took half of my mum's brains with him.
Of course, we can't forget my oh so beautiful sister Raven. It's like she took half my mum's beauty when she was born. Of course, that left me with nothing else except my talent. For painting.

My brother, at the moment, was at the university with Raven, probably drinking. Or flirting with some girl. Or both. I don't go to university, it's a waste of my, and the teacher's time. It's not like they could teach me anything anyway. I have the attention span of a goldfish. It goes in one ear and out the other.

Of course, I'm not all that bright either. I know that the average IQ is 100. I'm 84. When I got my IQ test back, it was like a wake up call. I would never be as smart as my brother, and I would never be as pretty as Raven. I'd just have to make do with what little I had.

I sat on the couch, making out with my boyfriend. Josh. We'd been going out for a few days now, and here we were. I wasn't really attracted to him. He was a bit of a dick to be honest. But I like annoying my brother.

I heard the door open and close, followed by footsteps, but I ignored it, continuing to make out with Josh, I pulled him on top of me, making sure that our appearance will annoy Charles to the fullest.

"Catherine Athena Xavier." A voice said. Without opening my eyes, I could tell exactly who it was. With his posh british accent. It was obviously Charles.

"What in the name of sanity do you think you're doing?" Charles continued. Very slowly, I pushed Josh away and opened my eyes, looking at Charles, smirking slightly.

"I'm making out with my boyfriend, what does it look like I'm doing?" Catherine replied snarkily. Watching in amusement as Charles' face turned a shade of pink.

Josh slowly stood up "I better be going." He said.

'Coward' Catherine thought, he was just leaving her to deal with Charles' wrath. Josh slowly bent down and planted a kiss on Catherine's forehead before making his way to the door, dodging Charles' tense body as he went.

After he'd left, Charles sighed, walking over to the couch and sitting down beside his younger sister, who had picked up a random book and started to read it. At that moment, Raven walked into the flat, frowning slightly at the silence.

"Woah." She said "Who died?" Looking between the two siblings, she could tell something had happened, most likely something that Catherine had done.

"My trust." Charles said, looking at Catherine "Catherine killed my trust."

Catherine scoffed "Oh come on Charles." She said "Your trust for me died years ago. Just because you hate me, doesn't mean you have to try and make me feel bad. Not that you are..."

"You really think that?" Charles asked, his face had visibly softened "You really think that I hate you?"

"No." Catherine said "I know that you hate me." She continued to 'read', ignoring the looks that Raven and Charles were giving to each other.

They both loved Catherine with all their heart, but they still felt bad for hiding their biggest secret from her.

When Charles was eleven, and Catherine was eight, he was forced to modify her memory in order to make her believe that Raven was her biological sister. And it killed him to know that every day, Catherine was living a lie.

Raven hated keeping her secret from Catherine. Despite knowing that Catherine wouldn't do anything to hurt them, they both agreed that it would be too much for her to handle.

Little did they know that Catherine was just like them.

Even if she didn't know it yet.
