"Y/n! Thank god you answered. There's a situation-" Stiles starts.

"No." I say stubbornly sat crossed-legged on the sofa.

"But it's-"

"Stiles I left Beacon Hills for a reason. I'm living a new life in London with Jackson and Ethan." I say.

Jackson my younger brother gives me a strange look. I'm two years old than him you see but was still involved in all of the supernatural especially when Jackson was. Jackson here may be younger but he is always extremely overprotective.

"Derek! It's Derek." Stiles shouts down the phone.

That has my attention.

"What about him? What's happened?" I ask with a small sense of urgency.

As on cue Jackson's eyes start rolling like bingo balls in the machine thing. You see me and Derek used to be a couple and was together for five years but he broke up with me. He says he was doing it for my own good to keep me safe but I didn't care about that I cared about him. I care about him.

"He's resorted back to his teenage self!" Stiles says dramatically.

Honestly I wasn't expecting that and choked on my water I sipped. Ethan shot up and patted me on the back till I gave a thumbs up.

"So he's what? Eighteen? God he was beautiful even back then..." I murmur.

"Oh brother." Jackson sighs.

"Yeah but he doesn't remember anything so far. He knows who he is but only at eighteen not what's happened since and-" Stiles pauses, "He's asking for you and his sisters. He doesn't remember the fire." Stiles continues cautiously.

"I'm coming."

Jackson falls off Ethan's lap as he jumps up to scramble after me. I start to gather essentials I need. I grab my phone charger and medication. Next I charge around getting a few bits and bobs for hand luggage followed by getting my emergency suitcase that is already packed. I've been in London just over a year now but I still keep an emergency packed case.

"Hey? Hey! What's going on?" Jackson asks me.

I whizz past him, "D-Derek has has-been reverted back to eighteen. Doesn't remember anything." I say quickly.

"Y/n, breathe. Remember what the doctor told you." Ethan looks at his boyfriend, "Jackson you're not helping winding her up." Ethan sighs.

"I'm coming with you." Jackson says calmer which calms me down slightly.

Me and Jackson are close and we were always joined at the hip. I watched every single one of his lacrosse games and I used to be the head cheerleader back in my day. God now I realise I literally had the American dream at Beacon Hills it was just Jackson didn't because of all the supernatural shit. I have still remained a human though.

"I'll come too babe to keep you both out of trouble." Ethan smiles to lighten the mood.

We took the flight that afternoon and arrived late morning the next day. Stiles and Scott managed to convince young eighteen year old Derek that I would see him in the evening. By this time me and Derek would have been dating for over a year and a half now. We were together aged seventeen to twenty-two. Ethan is now driving a keyed up Jackson and a mixed emotions me. I mean Jackson used to love Derek until about a year ago when the whole Jackson being a kanima thing. Jackson always felt terrible that because of that it tore me and Derek apart. It didn't though, me and Derek broke up long after that was sorted.

"Pumpkin!" Derek - or eighteen year old Derek who doesn't remember - says.

A gorgeous young Derek rushes to me before he can pull me in a kiss Jackson grabs his arm tight and pushes him away violently.

"Jackson, stop. He still doesn't remember anything since." Scott points out.

"What the hell Jackso-" Derek looks shocked, "You're not sixteen anymore. And you pumpkin you look older..." Young Derek trails off.

"What's that supposed to mean?" I snap.

"Y/n really?" Stiles sighs.

"Why do these people know me? Why is Jackson angry at me? Why are you not eighteen?" Derek says listing off questions.

"Derek just listen that's what we are trying to explain." Lydia says.

I go and give Lydia a hug.

"Derek you are not eighteen. You're actually... Uh, oh..." Kira starts.

"He's twenty-three." I state.

"You're actually older and you went away to Mexico. Somehow you've been reverted back to eighteen." Kira explains.

"How? Why?" Young Derek asks us.

"We don't know Derek." Ethan says calmly.

"Y/n? Maybe my mum can help or uncle Peter." Young Derek says, "Or Laura." He adds sounding positive.

I don't look at him, I can't. Kira, Malia and Lydia knows this and Malia gives me a quick hug. He's the young and carefree Derek. The Derek before the fire, the Derek before the breakup. His family was alive and his dreams big. We were happy then. He's still got that wonder in his eyes that I saw drain out of him after the fire.

"Derek, you're family are dead. They were killed in a fire. Peter is still alive but he's partially a maniac." Jackson says quietly.

"What?" He tears up, "Y/n baby, tell me this isn't true?" Young Derek says stroking my arm.

"Yes, it's true." I flinch away from his touch, "And don't call be baby or pumpkin." I say getting teary myself.

"Y/n not the time." Isaac points out.

"Why are you being like this Y/n?" Young Derek says getting upset.

"Derek you-"

"You broke her heart!" Jackson yells angrily, "You broke up with her over a year ago for her safety but she would have followed you anywhere man, anywhere." Jackson says getting passionate.

"Oh god." Stiles chimes in, head in his hands.

"I would never!" Young Derek shouts.

"You did." I say quietly, "You said it be safer for me if we were apart. You said you were doing it to protect me but what you didn't realise is you didn't protect me from myself."

"Now is not the time guys." Liam cuts in.

"What did I do?" I hear Derek whisper as he walks out of the room.
